FAQ

Speech to text, answered.

Yes. The uploader on this page and on every language page converts audio to text with no account, for files up to 2 minutes and 3 files a day. Longer files, up to 10 minutes and 10 MB each, need a free account and cost $0.00525 a minute, billed by the second.

No. There is no language setting. Valmiki STT detects the spoken language by itself, including speech that switches between languages mid-sentence, such as Hindi and English.

Because that is what Valmiki STT returned. For Telugu and Bengali, some runs of our test clips came back in Latin letters instead of the language's own script. Every sample is shown unedited so you know what to expect.

Yes, as plain text (TXT), a Word document (DOCX) or subtitles (SRT), with tabs for the language's own script, Roman letters and an English translation.

No. Sonex Labs has no voice-typing keyboard or phone app. Each language page explains how to voice-type with Gboard, Word, Windows or Google Docs, and what to use the uploader for instead.
