How speech to text works
A transcription engine analyzes the spoken audio in your recording, recognizes the words, and writes them out as punctuated text. Upload a file and get a clean transcript you can edit, search, and reuse.
Audio quality matters
Clear speech, low background noise, and one speaker at a time produce the most accurate text. Add names and technical terms to the custom vocabulary field to improve recognition. Files up to 60 minutes are supported for free.
What you can transcribe
Use speech to text for interviews, meetings, lectures, voice memos, calls, and any recorded conversation. Then copy the transcript as raw text, paragraphs, or sentences for your workflow.
Recordings, not live dictation
This tool transcribes uploaded files rather than streaming microphone input. Record your speech with any device first, then upload it here to convert speech to text accurately.
