Choose a language, play your media, and the extension generates captions from speech—even when the media has no subtitles or transcript of its own.\n\n<ol><li>Open a page with a video or audio player and hover over it. Audio players show the button when available.</li><li>Click the CC button next to the player.</li><li>Choose your language. The first time you use a language, its speech-recognition model is downloaded. Model files can be tens of megabytes and may take a moment to download. They are then stored in your browser for reuse.</li><li>Play the media. Captions appear as the audio is processed and follow playback, including when you pause or seek.</li></ol>\n\nSpeech recognition runs locally in your browser using the open-source Vosk engine through the voice2text library. Your media audio is not uploaded to a server. The extension downloads speech-recognition model files when needed; it does not send your audio or generated captions to a server.\n\n\nEnglish, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Ukrainian, Polish, Czech, Turkish, Arabic, Persian, Hindi, Chinese, Japanese, Korean, Vietnamese, Catalan, Kazakh, Uzbek, Breton, Esperanto, Greek, Swedish, Gujarati, Tajik, Telugu, Kyrgyz, Georgian, and Tagalog.\n\n<ul><li>Caption accuracy depends on the audio and language model. Background noise, music, and overlapping speakers can reduce accuracy.</li><li>Some websites use cross-origin media or protected streaming that prevents the extension from accessing audio. In those cases, captions may not be available.</li><li>Captions are generated as the media plays, so they appear shortly after the words are spoken.</li><li>For audio players, captions appear below visible players. For hidden audio elements, a floating control may appear after playback has been running for a few seconds.</li></ul>\n\nThis extension uses Vosk (Apache 2.0) and voice2text (MIT).\n\nFor privacy details, please see the linked Privacy Policy."},"developer_comments":null,"edit_url":"https://addons.mozilla.org/en-US/developers/addon/auto-captions-for-video-audio/edit","guid":"auto-captions-video-audio@mehdiabdi.com","has_eula":false,"has_privacy_policy":false,"homepage":null,"icon_url":"https://addons.mozilla.org/user-media/addon_icons/3095/3095569-64.png?modified=c661f6b9","icons":{"32":"https://addons.mozilla.org/user-media/addon_icons/3095/3095569-32.png?modified=c661f6b9","64":"https://addons.mozilla.org/user-media/addon_icons/3095/3095569-64.png?modified=c661f6b9","128":"https://addons.mozilla.org/user-media/addon_icons/3095/3095569-128.png?modified=c661f6b9"},"is_disabled":false,"is_experimental":false,"is_noindexed":false,"last_updated":"2026-10-16T20:25:28Z","name":{"en-US":"Auto Captions for Video & Audio"},"previews":[{"id":425331,"caption":null,"image_size":[889,549],"image_url":"https://addons.mozilla.org/user-media/previews/full/425/425331.png?modified=1791924026","position":0,"thumbnail_size":[533,329],"thumbnail_url":"https://addons.mozilla.org/user-media/previews/thumbs/425/425331.jpg?modified=1791924026"},{"id":425332,"caption":null,"image_size":[889,549],"image_url":"https://addons.mozilla.org/user-media/previews/full/425/425332.png?modified=1791924026","position":1,"thumbnail_size":[533,329],"thumbnail_url":"https://addons.mozilla.org/user-media/previews/thumbs/425/425332.jpg?modified=1791924026"},{"id":425338,"caption":null,"image_size":[719,133],"image_url":"https://addons.mozilla.org/user-media/previews/full/425/425338.png?modified=1791924026","position":2,"thumbnail_size":[533,99],"thumbnail_url":"https://addons.mozilla.org/user-media/previews/thumbs/425/425338.jpg?modified=1791924026"},{"id":425336,"caption":null,"image_size":[892,555],"image_url":"https://addons.mozilla.org/user-media/previews/full/425/425336.png?modified=1791924026","position":3,"thumbnail_size":[533,332],"thumbnail_url":"https://addons.mozilla.org/user-media/previews/thumbs/425/425336.jpg?modified=1791924026"},{"id":425334,"caption":null,"image_size":[889,555],"image_url":"https://addons.mozilla.org/user-media/previews/full/425/425334.png?modified=1791924026","position":4,"thumbnail_size":[533,333],"thumbnail_url":"https://addons.mozilla.org/user-media/previews/thumbs/425/425334.jpg?modified=1791924026"},{"id":425335,"caption":null,"image_size":[889,555],"image_url":"https://addons.mozilla.org/user-media/previews/full/425/425335.png?modified=1791924026","position":5,"thumbnail_size":[533,333],"thumbnail_url":"https://addons.mozilla.org/user-media/previews/thumbs/425/425335.jpg?modified=1791924026"},{"id":425337,"caption":null,"image_size":[892,555],"image_url":"https://addons.mozilla.org/user-media/previews/full/425/425337.png?modified=1791924026","position":6,"thumbnail_size":[533,332],"thumbnail_url":"https://addons.mozilla.org/user-media/previews/thumbs/425/425337.jpg?modified=1791924026"},{"id":425339,"caption":null,"image_size":[805,460],"image_url":"https://addons.mozilla.org/user-media/previews/full/425/425339.png?modified=1791924026","position":7,"thumbnail_size":[533,305],"thumbnail_url":"https://addons.mozilla.org/user-media/previews/thumbs/425/425339.jpg?modified=1791924026"}],"promoted":[],"ratings":{"average":0.0,"bayesian_average":0.0,"count":0,"text_count":0},"ratings_url":"https://addons.mozilla.org/en-US/firefox/addon/auto-captions-for-video-audio/reviews/","requires_payment":false,"review_url":"https://addons.mozilla.org/en-US/reviewers/review/3095569","slug":"auto-captions-for-video-audio","status":"public","summary":{"en-US":"Add automatic subtitles to web video and audio.
