Meta’s decision to cap Conversation Focus on its smart glasses reminded the accessibility community of a bigger point: Android phones have been doing live captioning for free for years, and the apps have quietly gotten very good. We tested seven live captioning apps for Android over two weeks, in situations that ranged from a coffee shop meeting to a phone call with a US carrier’s IVR to a lecture in French.
The short version: Live Transcribe covers 90% of everyday captioning needs and is free. Ava wins for team meetings and hybrid work. A couple of specialized apps are the right pick for phone calls or workplace situations. Here are the best live caption apps for Android in 2026.
What to look for in a live captioning app
- Latency. Sub-second latency is what makes captions readable during a conversation. Anything above two seconds falls behind and loses the thread.
- On-device vs cloud. On-device captioning works offline, keeps audio private, and drains battery faster. Cloud captioning is more accurate on accents and technical vocabulary.
- Room mic vs stream capture. Some apps caption the microphone (a room), some caption the phone’s audio stream (a call, YouTube, a Zoom), some do both. The right pick depends on your use case.
- Language support. English is universal. Beyond English, coverage varies wildly. Check French, Spanish, and Mandarin support if you need multilingual.
- Speaker labels. In meetings, labels for who is speaking make transcripts useful. Otter and Ava do this best.
- Phone call captioning. Captioning a phone call is technically difficult; only a couple of apps do it well, often through relay.

The apps
1. Live Transcribe, best for everyday rooms and speech
Live Transcribe is Google’s accessibility app and the reason most Android users never install anything else. It captions ambient speech from the phone’s mic in over 120 languages, runs on-device on Pixel and recent Samsung phones, and shows sound-event notifications for things like doorbells or a smoke alarm. Latency is sub-second on modern hardware.
The Sound Notifications feature is genuinely useful for anyone hard of hearing: the phone vibrates and flashes when it detects specific sounds you have trained. Pair it with Live Caption (built into the OS since Android 10) and most everyday captioning is already handled.
Where it falls short: No phone-call captioning. No stream capture from apps like Zoom or YouTube; those go through the OS-level Live Caption. No transcript history beyond the current session unless you save it manually.
Pricing: Free, no ads, no subscription.
Platforms: Android. Also runs on some Wear OS watches.
Download: Aptoide · Google Play
Bottom line: The pick to install first on any Android phone. Free, on-device, works in 120+ languages.
2. Ava, best for meetings and workplaces
Ava built its business around captioning workplace meetings, hybrid rooms, and one-on-one conversations at work for deaf and hard-of-hearing employees. The Android app pairs with a Chrome extension and desktop client so meeting audio from Zoom, Meet, Teams, or a conference-room mic feeds into the same transcript.
Speaker labels are automatic in a Meet or Zoom call, keyword search across past transcripts is included on paid tiers, and English accuracy sits in the mid-to-high 90s. Ava Scribe adds a human refiner behind the AI captions for professional-grade transcripts.
Where it falls short: Free tier caps you at five hours a month, which is thin for daily meeting use. Pro is expensive at $29 to $49 per month depending on plan. Cloud-only, so audio leaves the device.
Pricing: Free with 5 hours/mo. Pro $29/mo, Scribe from $99/mo with human refiner.
Platforms: Android, iOS, web, macOS, Windows, Chrome extension.
Download: Aptoide · Google Play
Bottom line: The pick if your employer covers accessibility tools and you need meetings captioned every day.
3. Google Meet, best for video meeting captions
Google Meet has built-in live captions in 15 languages, live translated captions in 40+ language pairs, and no need to install anything beyond the app you already use for calls. On Android, tapping the CC icon during a call switches captions on, and Workspace accounts can save the transcript to Drive.
For any meeting that already runs on Meet, the built-in captions are more than good enough and free of the app-switching that plagues Ava on the free tier.
Where it falls short: Only captions Meet calls. Does nothing outside the app. Language coverage is smaller than Live Transcribe. Translated captions are limited to Workspace and require account admin approval.
Pricing: Free with a Google account. Workspace from $6/user/mo unlocks translated captions and transcript export.
Platforms: Android, iOS, web.
Download: Aptoide · Google Play
Bottom line: If Meet is your video platform, do not install a third-party captioner for it. The built-in CC covers it.
4. Otter, best for team meetings with transcripts
Otter is a transcription service that doubles as a live captioning app because the transcript updates in real time. On Android, the Otter Assistant joins Zoom, Meet, and Teams calls and streams live captions with speaker labels, then keeps the transcript searchable afterwards.
For hybrid meetings where the transcript matters as much as the live captions, Otter is the pick. AI summaries and action-item extraction run after the call.
Where it falls short: Free tier limits you to 300 minutes per month with a 30-minute file cap. Only English, French, and Spanish. Cloud only; audio uploads to Otter servers.
Pricing: Free 300 min/mo. Pro $16.99/mo unlocks 1200 min. Business $30/user/mo.
Platforms: Android, iOS, web, Chrome extension.
Download: Aptoide · Google Play
Bottom line: The pick when the transcript is the deliverable and you want captions during the meeting and a searchable record after.
5. Nagish, best for real-time phone call captions
Nagish captions the other side of a phone call in real time on Android, with sub-second latency. You type or speak; the caller hears the audio; the caller’s speech is transcribed on your screen. It is a relay service designed for deaf and hard-of-hearing callers in the US.
The app is free for verified users in the United States. Nagish uses on-device AI to keep call audio off the internet where possible and never records conversations. Integration with the default phone app means outgoing calls route through Nagish automatically.
Where it falls short: Currently US-only. Requires an internet connection and a Nagish phone number as your outbound caller ID. Not usable for FaceTime or WhatsApp calls unless routed through the OS accessibility service.
Pricing: Free with US phone number verification.
Platforms: Android, iOS.
Download: Aptoide · Google Play
Bottom line: The pick for US-based deaf or hard-of-hearing users who want captioned voice calls without a certification process.
6. RogerVoice, best for European phone relay
RogerVoice is France’s answer to Nagish: real-time captioning of phone calls, with support for French Sign Language interpreters on paid tiers. The service is free for anyone with a recognized hearing disability in France under the CNSA disability compensation scheme, and the Android app handles both inbound and outbound calls.
For anyone in France, Belgium, or Switzerland, RogerVoice covers the phone-call gap that Live Transcribe leaves open.
Where it falls short: Regionally scoped. Works well in French; other languages depend on the interpreter’s availability. Free access requires the CNSA MDPH validation, which takes weeks.
Pricing: Free with disability certification. Otherwise pay per minute.
Platforms: Android, iOS.
Download: Aptoide · Google Play
Bottom line: The pick for French-speaking users who want captioned phone calls covered by the disability compensation system.
7. Innocaption, best for US relay-quality calls
Innocaption is the FCC-certified US caption phone service that runs entirely on Android. Every call is captioned in real time by a mix of AI and live human captioners, so accuracy is higher than pure AI relays on unusual accents or technical vocabulary.
The app registers a dedicated phone number and integrates with the dialer, so anyone calling that number reaches you captioned. Voicemail is transcribed too.
Where it falls short: US-only. Requires FCC self-certification of hearing loss to activate free service. Human captioning has slight added latency vs AI-only.
Pricing: Free after FCC self-certification of hearing loss.
Platforms: Android, iOS.
Download: Aptoide · Google Play
Bottom line: The pick when caption accuracy on a specific voice matters more than latency, thanks to the live-captioner fallback.
How to pick the right one
- If you install one live-caption app, install Live Transcribe. Free, on-device, 120+ languages.
- If you run meetings on Zoom or Teams: Ava for the captions, Otter if you also need transcripts.

- If you need phone calls captioned in France: RogerVoice.
- For students in lectures: Live Transcribe running in the pocket, or Otter if the professor allows recording.
FAQ
What is the best free live caption app for Android?
Live Transcribe by Google is the best free live caption app for Android in 2026. It captions ambient speech in over 120 languages, runs on-device on modern hardware, and includes sound-event notifications for accessibility. There is no paid tier.
Can I caption a phone call on Android?
Yes. Nagish and Innocaption in the US, RogerVoice in France, caption live phone calls in real time. General-purpose captioners like Live Transcribe cannot capture phone-call audio directly due to Android’s audio routing rules.
Do live caption apps work offline?
Live Transcribe runs on-device on Pixel and recent Samsung phones, so it captions offline. Ava, Otter, Nagish, and Google Meet require an internet connection. Android’s OS-level Live Caption also runs on-device for media playback.
How accurate is Google Live Transcribe?
Word accuracy on clean English audio sits in the mid-90s, comparable to premium captioning services. Accuracy drops on strong accents, heavy background noise, and technical jargon. In tests it handled British, Australian, Indian, and Singaporean English above 90%.
Can Live Transcribe caption a Zoom call?
Not directly. Live Transcribe uses the microphone, so it captions the room speaker output rather than the call audio stream. For Zoom, use Ava or Otter, which pair with the Zoom API for cleaner audio, or Zoom’s own built-in captions.
Is there a live caption app for glasses like Ray-Ban Meta?
Ray-Ban Meta and similar smart glasses offer their own conversation focus, but with caps on free usage. On the phone side, Live Transcribe paired with a Bluetooth earpiece is a battery-friendly alternative that costs nothing.
