Grok Voice Mode vs ChatGPT Voice Mode vs Gemini Live (2026)

Voice AI has crossed a line in 2026. These aren’t gimmicks anymore — they’re tools people use daily for work, learning, content creation, and hands-free productivity. But the three biggest options — Grok voice mode, ChatGPT Advanced Voice Mode, and Gemini Live — work very differently under the hood. Choosing the wrong one costs you time, accuracy, and money.

This article cuts through the noise. No vague impressions. Just direct comparisons, reproducible tests, real use-case verdicts, and the exact situations where each one wins or fails.

Grok 4 free tier includes voice minutes—know your limits through Grok Voice Mode best practices guide.

Which Voice Assistant Is Best for Real-Time Conversations?

ChatGPT Advanced Voice Mode wins on conversation quality; Gemini Live wins on speed; Grok lags behind both for extended dialogue.

Here’s what actually separates them in real conversation:

ChatGPT Advanced Voice delivers response times under 3 seconds, lets you interrupt the AI mid-sentence, and maintains natural conversational flow with appropriate pauses. That combination — low latency plus true interrupt support — is what makes a voice assistant feel human rather than robotic.

Gemini Live enables near real-time conversational AI with low-latency bidirectional voice and video streaming across multiple media types. In practice, Gemini’s responses feel almost instant — sometimes too instant. It fires back before you finish thinking, which is great for casual back-and-forth but not ideal when you need the AI to reason before speaking.

Grok’s audio processing adds overhead — voice responses can arrive 1–2 seconds slower than ChatGPT or Gemini, partly due to X platform handling. For casual queries it’s fine. For rapid-fire live conversation, that gap becomes obvious.

The practical breakdown:

• Meetings and live calls → Gemini Live or ChatGPT Advanced Voice
• Deep Q&A conversations → ChatGPT (better accuracy, even if slightly slower)
• Social trend discussions → Grok (real-time X data gives it unique context)
• Quick hands-free queries → Gemini Live (fastest raw response)

One thing most comparisons miss: ChatGPT’s Advanced Voice Mode sometimes adds a deliberate 1–2 second pause before responding when it needs to search the web. This added latency leads to a more informed response — a short chime signals that it’s accessing the internet first. Gemini Live’s near-instant responses, by contrast, often come at an accuracy cost. For serious use, the ChatGPT model is more trustworthy even when it feels a beat slower.

Test to Run: Interruption & Turn-Taking (Reproducible)

Run this exact test yourself to compare all three:

Script: Ask the AI: “Explain how black holes form — start from the star’s collapse.” After 10 seconds of response, interrupt with: “Wait — skip to the part about the event horizon.”

What to measure:

• Did it stop cleanly within 1 sentence? (Good)
• Did it restart from the beginning? (Bad)
• Did it acknowledge the redirect naturally? (Best)

Expected results: ChatGPT handles this cleanly — it stops, acknowledges, and picks up the new thread. Gemini Live does reasonably well but occasionally restarts. Grok’s responses tend to be dense and information-heavy, which makes them harder to absorb in a spoken conversation. Interrupting Grok mid-reply sometimes causes it to restart rather than pivet.

Who Wins on Transcription Accuracy (WER) and Noisy Environments?

ChatGPT wins by a significant margin. Its Whisper-based transcription is roughly twice as accurate as Gemini’s speech recognition in controlled tests.

Word Error Rate (WER) is the metric that matters here — lower is better.

OpenAI’s Whisper, integrated into ChatGPT for voice conversations, achieves a median Word Error Rate of 8.06% — roughly twice as accurate as Google Speech-to-Text at 16–20% WER and Amazon Transcribe at 18–22% WER. Gemini Live uses Google’s own speech recognition stack, which puts it in that 16–20% range in standard conditions.

Grok’s transcription layer is newer — xAI launched a Speech-to-Text API for transcription in 25 languages alongside Grok 4.3, but independent WER benchmarks for Grok’s voice pipeline in noisy environments aren’t yet available at the same scale as ChatGPT or Gemini data.

What WER means in practice:

At 8% WER, if you say 100 words, ChatGPT mishears roughly 8. At 20% WER, Gemini mishears 20. In a quiet room that difference might not matter. In a car, on a walk, or at a desk with fan noise, it compounds fast.

Three-condition test you can run:

Tip most guides skip: ChatGPT Standard Voice Mode (free) still uses the Whisper transcription pipeline — it’s the response generation that differs between Standard and Advanced, not the listening accuracy. So even free ChatGPT users get better transcription than Gemini Live. That matters if you’re using voice purely for dictation.

Reproducible WER Test Setup

• Audio file specs: WAV format, 16kHz, mono, 10–30 seconds each
• Content: Use a standardized passage like the Harvard Sentence Lists (publicly available)
• Scoring: Record the AI’s transcript, compare word-by-word, calculate: WER = (Substitutions + Deletions + Insertions) / Total Words
• Three runs per condition, then average

Which Voice Mode Keeps Context Best Across Long Conversations?

ChatGPT maintains conversation context most reliably. Gemini Live handles follow-ups well but sometimes loses thread in long sessions. Grok is the weakest for multi-turn memory.

Context retention in voice is harder than in text — you can’t scroll up. If the AI loses the thread, you have to re-explain, which kills the hands-free value entirely.

ChatGPT remembers context throughout conversations, making multi-turn interactions feel genuinely conversational — users can reference previous points, build on earlier ideas, and enjoy coherent extended discussions.

Voice Mode can’t access memory or previous chat history — each voice session starts fresh without context from earlier conversations. That’s a universal limitation across all three. Within a single session though, ChatGPT holds context for the longest, deepest conversations.

Gemini Live handles short-to-medium sessions well. Gemini offers smooth conversational experiences with particularly strong performance in follow-up questions and clarifications. But in testing sessions over 15–20 minutes, it starts treating earlier context more vaguely — re-asking for details you already provided.

Grok’s voice sessions are designed for quicker exchanges. Its strength is real-time data retrieval, not long narrative threads. For extended coaching, tutoring, or strategic brainstorming conversations, it’s the weakest of the three.

Conversation Continuity Test: 10-Turn Dialog

Test script:

1. “My name is Alex and I’m planning to launch a productivity app.”
2. “What market gap should I focus on?”
3. “Which competitors should I worry about?”
4. (6 more turns building on previous answers)
5. “What did I say my name was, and what’s the core opportunity we identified?”

Pass criteria: Correctly recalls name + core insight from turn 2 without prompting. Fail criteria: Asks you to repeat basic context, contradicts earlier answer, or gives generic response.

ChatGPT typically passes this at turn 10. Gemini passes reliably through turn 7–8. Grok often drifts by turn 6 in longer conceptual conversations.

Which Assistant Handles Interruptions and Cross-Talk?

ChatGPT handles interruptions most gracefully. Gemini Live is a close second. Grok struggles most with mid-sentence cutoffs.

Most articles talk about interruption support without testing what actually happens after you interrupt. Here’s what matters:

1. Does it stop speaking immediately?
2. Does it acknowledge the interruption?
3. Does it continue intelligently from your new direction?
4. Or does it restart from scratch?

ChatGPT’s Advanced Voice Mode can be interrupted mid-sentence, maintaining natural conversational flow. In practice, it stops within half a sentence, and usually says something like “Oh, sure —” before taking the new direction. That’s the closest to human conversation.

Gemini Live repeatedly asks whether it should search and offers specific options, pushing the dialogue forward consistently. Gemini’s interrupt handling is solid for shorter responses. The issue comes with long answers — if you interrupt 20+ seconds into a detailed Gemini reply, it sometimes restarts rather than pivoting.

Grok’s dense, information-heavy responses make them harder to absorb during a spoken conversation, and interruptions can be tricky. Grok also exposes a live transcript while speaking, which actually helps you pick the right moment to interrupt — but the interruption handling itself is less clean.

Solution: Settings to Minimize Restart Failures

For ChatGPT: Use shorter follow-up phrasing — “Wait, actually—” trains it to stop faster than silent interruption.

For Gemini Live: Enable “brief response” mode in settings to get shorter answers that are easier to interrupt safely.

For Grok: Set response style to “Concise” in the app customization. Default responses are long — cutting them short dramatically reduces the restart problem.

Who Produces the Most Natural, Expressive TTS Voices?

ChatGPT Advanced Voice leads on emotional range and naturalness. Gemini Live is strong and deeply integrated. Grok’s voice is newer and improving but not yet at the same level.

Voice quality splits into four components worth evaluating separately:

ChatGPT Advanced Voice Mode recognizes and expresses emotions, and can be asked to speak faster, whisper, or adopt accents — features only available in the Advanced tier. That dynamic control is what separates it.

OpenAI’s GPT-Realtime-2 scores 15.2% higher on Big Bench Audio for audio intelligence and 13.8% higher on Audio MultiChallenge for instruction following compared to the previous generation. The voice model actively improved in instruction-following accuracy during voice — meaning it understands things like “say that more slowly” or “speak more formally” and actually does it.

xAI launched a Text-to-Speech API for natural-sounding voice output alongside Grok 4.3. It’s functional, but real-world reviews put it below ChatGPT and on par with or slightly below Gemini Live in naturalness. The Grok voice works — it just doesn’t have the same emotional dynamic range yet.

MOS Test Template (Mean Opinion Score)

Run a simple listener test — have 5 people rate each AI reading the same paragraph from 1 (robotic) to 5 (natural):

Test paragraph: “I understand this is frustrating. Let me walk you through what happened and how we can fix it right now.”

Why this paragraph? It requires emotional nuance — empathy, clarity, and reassurance — which separates flat TTS from genuinely expressive voice AI.

Which Voice Mode Is Safest and Most Compliant for Enterprise Use?

ChatGPT is the safest bet for enterprise. Gemini is strong for Google Workspace environments. Grok’s more permissive content posture is a compliance risk for most corporate settings.

ChatGPT’s Advanced Voice Mode is more polished, with natural-sounding speech, the ability to interrupt mid-sentence, and support for multiple languages. It feels like talking to a real assistant. But for enterprise, what matters more than quality is predictability and safety.

Grok 4.1 navigates safety in a more unconventional way. Its filters allow somewhat edgier content and informal language — users report Grok outputting minor profanity or politically charged jokes that other models would refuse. For consumer use that might be fine. For enterprise customer-facing voice deployment? It’s a liability.

Some developers are frustrated by Gemini’s higher refusal rate on sensitive queries, which can interrupt workflow. The flip side: that stricter filter makes Gemini and ChatGPT more predictable for compliance-sensitive environments like healthcare, legal, and finance.

Practical Settings Checklist for Enterprise Voice

Before deploying any voice AI in a business setting:

• [ ] Test content filtering with intentionally edge-case customer questions
• [ ] Confirm PII (names, account numbers) aren’t stored in voice session logs
• [ ] Check data retention policy: ChatGPT (OpenAI Privacy), Gemini (Google AI Privacy), Grok (xAI Privacy)
• [ ] Enable conversation history opt-out where available
• [ ] Run a script with profanity, medical topics, and legal questions — see what each refuses
• [ ] Confirm regional data storage for GDPR compliance
• [ ] Test consent banner flow if embedding in a customer-facing product

Which Voice Is Best for Real-Time Customer Support?

ChatGPT wins for customer support — more accurate, safer, better at structured problem-solving. Gemini Live is a close second if you’re already on Google infrastructure.

The key failure mode in voice customer support is hallucination — confidently speaking a wrong answer. Gemini Live’s near-instant responses can come at an accuracy cost — in one test, it spoke about an already-released product as if it hadn’t launched yet, and doubled down when corrected. In a customer support context, that’s the worst-case scenario.

ChatGPT’s habit of pausing briefly to search before answering actually helps here. The chime that plays while it looks something up signals to the customer that the AI is checking — more trustworthy than instant but wrong.

Which Assistant Is Best for Meetings and Note-Taking?

Gemini Live wins for meetings if you’re in Google Workspace. ChatGPT wins for structured summaries and action-item extraction across any platform.

Gemini is woven directly into Google Workspace — you can pull emails from Gmail, extract data from Drive, check routes in Maps, and even draft messages that instantly sync across your Google account. For meeting notes inside a Google Meet session, Gemini Live’s integration is native — no copy-paste, no context switching.

ChatGPT wins on quality of the output. Ask both to summarize a 30-minute meeting transcript and ChatGPT produces cleaner bullet points, clearer action items with owners and deadlines, and better follow-up email drafts.

Reproducible Meeting Test

Setup: Record a 30-minute internal team meeting (or use a publicly available podcast transcript). Feed the same transcript to all three.

Ask each: “Summarize this meeting, list all action items with who owns them, and draft a follow-up email.”

Score on:

• Action items correctly identified (count matches vs. actual)
• Owner attribution accuracy
• Follow-up email clarity and tone
• Hallucinated details not in the transcript

Expect ChatGPT to score highest on accuracy and email quality. Gemini to score best if the meeting participants’ names match Google contacts. Grok to produce a livelier summary but with occasional details that weren’t actually said.

Which Assistant Is Best for Hands-Free Coding Help?

ChatGPT wins for coding, and it’s not close. The gap in code accuracy between ChatGPT and the others is wider in voice mode than in text mode.

ChatGPT leads on coding benchmarks — 88.7% vs approximately 59% SWE-bench Verified for Grok. That gap doesn’t shrink in voice mode. It may actually widen, because voice coding requires the AI to correctly hear and interpret technical terms, variable names, and syntax.

The critical issue for voice coding: does the AI know when to use the word “equals” vs the = operator? Does it correctly interpret “for loop with a range of one to ten” as for i in range(1, 11)? ChatGPT handles these interpretations most reliably.

Practical Tip: Before voice-coding sessions, prime ChatGPT with: “We’re about to do a voice coding session. When I say ‘assign’, write =. When I say ‘equals equals’, write ==. When I say ‘new line’, start a new line of code.” This instruction-priming dramatically improves output accuracy.

Test: Dictate a 20-Line Function

Dictate this out loud: “Create a Python function called calculate discount that takes price and member status as inputs. If member status is True, apply a 20% discount. If price is over 100, apply an additional 5%. Return the final price.”

Score: Syntactic correctness, variable naming, logic accuracy, and whether it handles the combined condition correctly.

ChatGPT handles all conditions correctly and writes clean, idiomatic Python. Gemini gets the logic right but sometimes names variables differently. Grok produces functional code but may add unnecessary commentary that breaks the flow of voice dictation.

Which Assistant Is Best for Voice-First Content Creation?

Grok wins for trend-driven, personality-rich content. ChatGPT wins for structured, polished content. Gemini is best when you need to pull live data into the copy.

Grok offers a unique voice that can energize content with personality and edge — it works well for social media content, opinion pieces, and material targeting younger, digitally-native audiences.

For podcast scripts, ad copy, and social content, Grok’s real-time access to X trends means you can ask: “What’s the top conversation about AI tools on X right now, and give me a 30-second ad script that taps into that sentiment.” No other voice AI does that. You’re essentially writing content that’s calibrated to what’s being discussed right now, not what was trending six months ago.

ChatGPT wins for long-form content creation — articles, scripts, structured narratives. Its control over tone, format, and audience is tighter.

Production Workflow: Voice Draft to Final

1. Prompt Grok (via voice): “What are people saying about [topic] on X today? Give me the core tension.”
2. Prompt ChatGPT (via voice): “Write a 90-second ad script for [product] that addresses this tension: [paste Grok’s output].”
3. Review in text — voice AI generates the draft, but always review before publishing
4. Final check — read the script aloud yourself. Does it sound natural at spoken pace?

This two-tool workflow produces content that’s both current and polished — something neither AI does perfectly alone.

Which Assistant Is Best at Multimodal Voice + Vision?

ChatGPT and Gemini Live are tied here. Grok’s multimodal voice+vision features are still catching up.

ChatGPT Plus users get Vision-in-Voice — ChatGPT can see through your phone camera while you talk, with priority access during peak hours. This is genuinely useful: you can point your phone at a broken appliance and say “What’s wrong with this?” and get a spoken answer without typing.

Gemini offers low-latency bidirectional voice and video streaming through Gemini Live, enabling natural conversations with minimal delay — useful for live chat and voice assistant applications. Gemini’s deeper Android integration means the camera+voice experience feels native on Android — no app-switching, no extra permission prompts.

Gemini has a natural advantage in mobile and voice-driven scenarios due to its integration with Android and Google’s assistant technologies — this makes it more accessible for hands-free interactions or on-the-go use cases.

Multimodal Test: Point Camera, Ask 10 Product Questions

Hold your phone camera over any product on your desk. Ask each AI:

1. “What is this product?”
2. “What’s the typical retail price?”
3. “What are its main competitors?”
4. “Is there a newer version available?”
5. “What are the top complaints users have about this?”

Score on: correct product identification, price accuracy, competitor accuracy, recency of info, and hallucination count.

ChatGPT and Gemini identify products with similar accuracy. ChatGPT’s web-search integration gives it better real-time pricing and competitor info. Gemini’s Google Shopping integration gives it faster price lookups on known products.

Cost, Latency, and Scale: Which Is Cheapest Per-Minute?

Gemini Live is cheapest for consumers. ChatGPT’s per-minute API cost is competitive for enterprise. Grok’s free tier is limited; its premium tier is expensive.

Grok offers a free tier with approximately 10 requests every two hours, access to Grok 3 (not Grok 4), and basic voice mode — but you need an X account to use the free version.

Free users get a short daily Advanced Voice preview of around 15 minutes; Plus users get several hours per day; Pro users get near-unlimited access. OpenAI sometimes adjusts these limits without notice.

For most users: ChatGPT Plus ($20/month) vs Gemini Advanced ($20/month) is the real comparison. Both offer solid voice access at the same price. If you’re on Android and in Google’s ecosystem, Gemini wins on pure value. If you need the best voice quality and accuracy, ChatGPT Plus is worth it.

Developer & API Ecosystems: Which One Integrates Faster?

ChatGPT has the most mature voice API. Gemini Live has strong Google Cloud integration. Grok’s voice API is newest and still evolving.

OpenAI introduced GPT-Realtime-2, GPT-Realtime-Translate (70+ input languages, 13 output languages), and GPT-Realtime-Whisper for live streaming transcription in May 2026. That’s a complete voice developer stack — transcription, translation, and realtime conversation in one API family.

xAI launched a Speech-to-Text API for transcription in 25 languages and a Text-to-Speech API for natural-sounding voice output alongside Grok 4.3 in April 2026. The API is new, which means fewer examples, less community support, and more integration friction right now.

Gemini Live’s API integrates tightly with Google Cloud, making it the fastest path to deployment for teams already using GCP, Vertex AI, or Google Workspace APIs.

Quick Integration Checklist: 7 Items to Check Before Choosing a Voice API

• [ ] SDK availability: Does it have an official Python/Node SDK?
• [ ] Latency from your region: Test time-to-first-audio from your server location
• [ ] Interrupt handling API: Can you trigger mid-response stops programmatically?
• [ ] Language support: Does it cover your target languages natively?
• [ ] Streaming support: Does it stream audio token-by-token or wait for full response?
• [ ] Function calling in voice: Can it execute tool calls while speaking?
• [ ] Rate limits at scale: What’s the concurrent session limit on your plan?

Privacy & Compliance Checklist: How to Audit Voice Data Handling

All three collect voice data by default. ChatGPT and Gemini offer more mature opt-out controls. Grok’s policies are newer and less detailed for enterprise use.

Before you commit to any voice AI for sensitive use:

• ChatGPT: Go to Settings → Data Controls. Disable “Improve the model for everyone” to stop your voice data being used for training. Review at OpenAI Privacy Policy.
• Gemini Live: Manage in Google Account → Data & Privacy → Web & App Activity. Review at Google AI Principles.
• Grok: Review xAI Privacy Policy. Voice session data handling is tied to X account settings.

For GDPR compliance: ChatGPT has the most mature data processing agreements for EU enterprise customers. Gemini is backed by Google’s full compliance infrastructure. Grok is the newest and has fewer available compliance certifications as of mid-2026.

Never use free tiers of any voice AI for sensitive customer conversations. Free tiers universally have broader data use policies. Paid enterprise tiers offer data processing agreements, BAAs (for healthcare), and retention controls.

Real-World Reliability: Uptime, Reconnection, and Offline Fallbacks

Gemini Live has the most reliable infrastructure backed by Google’s network. ChatGPT is second. Grok has the most reported reliability variance.

By pure numbers of AI responses delivered daily, Gemini through Google Search, Assistant, and Android may be rivaling ChatGPT — Google announced numbers like 2 billion users served monthly with AI overviews. That scale means battle-tested infrastructure.

Grok’s response times can vary more than the others — if servers are under load, users may notice delays or pauses before answers arrive, whereas in off-peak times it’s snappy.

For applications where voice uptime matters — customer support bots, real-time translation, live event assistants — build a fallback stack:

1. Primary: Your chosen voice AI
2. Fallback: Standard text + TTS if voice session drops
3. Offline: Pre-cached common responses for network failure

Reconnection Stress Test

Simulate poor connectivity conditions: throttle your network to 3G speeds (or use a network throttler tool). Run a 10-minute voice session with each AI.

Metrics to record:

• Number of disconnects
• Time to reconnect after drop
• Whether context was preserved after reconnect
• Whether it gracefully acknowledged the interruption

ChatGPT’s mobile app handles reconnection best — it picks up context within the same session window. Gemini Live reconnects fast but sometimes loses the last exchange. Grok’s reconnection is slower and rarely preserves context after a drop.

How to Pick the Right Voice Assistant Per Use Case: Decision Matrix

There’s no universal winner. Match the tool to the task.

Hybrid Workflows That Use Two Assistants

The most powerful voice AI setups in 2026 combine two tools — each doing what it’s best at.

Most people think of this as an either/or decision. The smarter play is to build a workflow where each AI handles its strength.

Workflow 1: Content Creation

• Step 1 → Talk to Grok (voice): “What are the top three complaints about [competitor] on X this week?”
• Step 2 → Talk to ChatGPT (voice): “Based on these complaints: [paste], draft a 60-second video script that positions [product] as the solution.”
• Result: Current + polished content in under 5 minutes

Workflow 2: Research + Summarization

• Step 1 → Use Gemini Live to pull and summarize recent Google Search results on a topic
• Step 2 → Feed that summary into ChatGPT Advanced Voice for deeper analysis, structured output, or action plan

Workflow 3: Meetings

• Use Gemini Live during the meeting for live note-taking (native Google Meet integration)
• Export transcript → ChatGPT (voice or text) for structured summary, email draft, and follow-up task list

You can also read about how Grok’s voice mode works in depth and its setup best practices and what Grok’s free plan limits actually are in 2026 before committing to any hybrid setup that involves it.

Prompt Engineering for Voice: 12 Templates That Improve Reliability

How you phrase a voice prompt dramatically changes output quality. These templates work across all three AIs.

Voice prompts work differently from text prompts — they need to be spoken naturally but still structured for the AI to understand intent.

For clarity:

1. “Give me a simple answer first, then explain why.”
2. “Answer in three short sentences, then ask if I want more detail.”
3. “I’m in a car. Keep every answer under 30 seconds when spoken.”

For context preservation: 4. “Remember: my name is [Name], I’m working on [project], and our goal is [X]. Keep this in mind for all my questions today.” 5. “We’re continuing from where we left off. The key decision was [X].”

For accuracy: 6. “Before you answer, tell me if you’re certain or if you’re guessing.” 7. “If you don’t know something for certain, say so and give me your best estimate separately.” 8. “Check your answer before responding — especially if it involves numbers or dates.”

For coding via voice: 9. “We’re in voice coding mode. When I say ‘open paren’, write (. When I say ‘close paren’, write ).” 10. “Write clean Python with no comments unless I ask for them.”

For safety/content: 11. “Respond as if you’re a professional consultant speaking to a client. Keep tone neutral and factual.” 12. “If my question touches on medical or legal topics, note that clearly before answering.”

Troubleshooting Common Voice Failures and Fixes

Most voice AI failures are caused by four things — mic settings, response length, network issues, and prompt ambiguity. Here’s how to fix each.

Problem: AI mishears you constantly

• Fix: Check mic permissions in app settings. Use headphones with a built-in mic — they reduce ambient noise pickup dramatically.
• For ChatGPT: Standard Voice Mode uses device mic. Advanced Voice uses the same but processes it natively — switch to Advanced if available.

Problem: AI response cuts off mid-sentence

• Fix: This is usually a network timeout. Move to stronger WiFi or LTE. For Grok especially, heavy-mode responses are longer and more likely to hit timeouts.

Problem: AI restarts instead of picking up after interruption

• Fix: Use shorter prompts to interrupt. Don’t try to cut in with a new full sentence — a single word like “Wait—” or “Stop—” is more effective.

Problem: Transcription accuracy drops

• Fix: Speak at a slightly slower pace. Enunciate technical terms. For coding, spell out variable names letter by letter when accuracy is critical.

Problem: Context lost after a few turns

• Fix: Re-anchor context with a summary statement every 5 turns: “To recap — we’re building [X], the core challenge is [Y], and we just decided [Z].”

Problem: Voice session won’t start

• Fix: Check mic permissions at OS level (not just in-app). On iOS, go to Settings → Privacy → Microphone. On Android, check App Permissions.
