HexCaptions: Live Captions

HexCaptions turns speech into real-time captions: live captions and live subtitles for any video playing on your phone, and speech to text for anyone talking near you. Speech recognition runs on your device, so your audio never leaves it, and once a language is downloaded it works offline.
Made for people who are deaf or hard of hearing, for watching videos with the sound off, for following a lecture or a meeting, and for understanding videos in a language you don't speak.
LIVE CAPTIONS FOR ANYTHING ON YOUR PHONE
• Live captions for videos, podcasts, voice messages, livestreams and most video apps.
• Floating captions stay on top of the app you're watching, like subtitles. Drag them anywhere, resize the text, pause or stop.
• Choose one app to caption, or caption everything your phone plays.
SPEECH TO TEXT FROM THE MICROPHONE
• Voice to text in real time: live transcription of conversations, classes, lectures, meetings and talks.
• Show the transcript in big, full-screen text to someone across the table.
• Every session is saved as a transcript you can search, rename, copy and export.
SUBTITLES FOR YOUR VIDEOS
• Subtitle maker for videos and recordings: pick a file, or share it from any app, and get subtitles made on your phone.
• Transcribe audio to text and export subtitles as SRT or VTT files, or plain text.
• Translate subtitles into another language before you export.
TRANSLATE SPEECH AS YOU LISTEN
• Live translation of captions into 50+ languages, on your device.
• Show the translation, the original, or both, one above the other.
• Watch videos in a language you're learning with translated live subtitles.
ACCURATE SPEECH RECOGNITION IN 60+ LANGUAGES
• Whisper AI speech packs for 60+ languages: better with accents, songs and speech over music.
• Standard speech packs for nearly 30 languages: fast and light for everyday speech.
• English, Spanish, Hindi, Arabic, Chinese, Japanese, Korean, French, German, Portuguese, Russian, Indonesian, Turkish, Italian and many more.
PRIVATE AND OFFLINE
• Offline speech to text: captions keep working without internet once a language is downloaded.
• Your audio is never recorded or uploaded, and no account is needed.
• Optional: connect your own LibreTranslate server for translation.
EASY TO READ
• Choose the caption text size, number of lines and background.
• Light and dark themes, with your wallpaper's colors or a color you pick.
• The app is available in English, Arabic, Chinese, French, German, Indonesian, Italian, Russian and Spanish.
GOOD TO KNOW
• Needs Android 10 or later.
• Standard packs run on almost any phone. Whisper packs need more processing power and work best on recent phones.
• Some streaming apps block other apps from capturing their sound, so their audio can't be captioned.
• Most video apps pause when you switch away from them. To read captions while watching, use floating captions.
• Floating captions need the "Display over other apps" permission, which Android Go phones don't offer.
• Why microphone access? Android requires it to capture other apps' sound. HexCaptions only listens to your surroundings when you choose Microphone.
