Speech to Text FAQ
Is my audio uploaded to a server?
No. The AI model (about 280MB) is downloaded to your browser once and cached — every audio file after that is transcribed entirely on your device and never leaves it.
How accurate is the transcription?
It uses OpenAI's open-weight Whisper model (the same family used by many paid transcription tools), so accuracy is generally strong for clear speech. Background noise, heavy accents, or overlapping speakers can reduce accuracy — always skim the transcript before using it.
Which languages does it support?
The multilingual Whisper model used here supports dozens of languages, including English and Hindi/Hinglish content.
What audio formats are supported?
MP3, WAV, M4A, OGG, and FLAC, up to 100MB.

Speech To Text
Transcribe audio files to text with timestamps using AI speech recognition that runs in your browser.

It is useful for interview writeups, voice note cleanup, lecture and meeting notes, and any workflow where turning spoken audio into searchable text saves time over manual note-taking.
