How to use the Audio to Text (AI Transcription)
Typing out a recording by hand takes about four times as long as the recording itself. This free audio to text converter does it for you with Whisper, the open-source speech recognition model released by OpenAI, running entirely inside your browser.
Choose a file or record straight from your microphone. The tool decodes the audio on your device, then the AI listens in 30-second windows and writes what it hears, with timestamps. “Fast” (Whisper Tiny, about 41 MB) is quick and fine for clear speech; “Accurate” (Whisper Base, about 77 MB) makes fewer mistakes with accents and background noise. It downloads once, then is cached.
Whisper understands 99 languages. Leave the language on automatic or choose it yourself for better results, for example Hindi or Punjabi. When it finishes, edit the text in the box, copy it, or download a TXT file, or SRT and VTT subtitle files with timings for YouTube or CapCut.
Laptops are faster than phones; keep the tab open while it works. Like any speech recognition, it can mishear names, numbers and quiet or overlapping voices, so check important details before you use the transcript.
VSH take: most “free” transcription sites upload your recording to their servers and limit you to a few minutes. Here the model runs on your device, so there is no time limit, no account and nothing to leak.
Frequently asked questions
Is my audio uploaded anywhere?
No. The Whisper model is downloaded to your browser and the transcription runs on your device. Your file is never sent to a server.
Is it really free and unlimited?
Yes. There is no account, no watermark and no minute limit. Very long files simply take longer, so keep the tab open.
Which file types work?
Any audio your browser can play: MP3, WAV, M4A, AAC, OGG, Opus, FLAC and WebM, and the sound in MP4, MOV and WebM videos.
Which languages does it support?
Whisper recognises 99 languages, including English, Hindi, Punjabi, Urdu, Spanish, French, Arabic and Chinese. It can also translate speech into English.
How do I make subtitles for a video?
Choose the video file, press Transcribe, then download the SRT or VTT file and add it in your video editor or on YouTube.
How accurate is it?
Clear speech in a quiet room is usually very accurate. Accents, music and several people talking at once cause more mistakes; the Accurate model helps.
