How to convert Text to speech

  1. Drop the text file.
  2. Pick the voice and pace.
  3. Press Read and download the audio.

What happens to your file

espeak-ng turns the words into phonemes, a Piper voice model turns the phonemes into 22 kHz speech on Fylane’s servers, and ffmpeg packs it as MP3. Nothing is sent to a third party; the voices are open (MIT) and run entirely here.

Markdown marks and HTML tags are stripped before reading; code blocks are skipped. Names, acronyms and numbers are read as the phonemizer guesses them — write them out where it matters.

Questions

Other languages?

English (US and UK) for now. Piper has voices for thirty languages; say which you need.

How long can the text be?

6 000 characters at a time — about ten minutes of speech, a few minutes to make. Split a longer piece by section.

Do this in code

curl -X POST https://api.fylane.dev/v1/jobs \
  -H "Authorization: Bearer $FYLANE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "file_id": "<file id>",
    "operation": "speech.synthesize",
    "options": {
      "voice": "en_US-lessac-medium",
      "speed": 1,
      "format": "mp3"
    }
  }'

The same operation, speech.synthesize — Text read aloud by a Piper voice (`voice`: en_US-lessac-medium or en_GB-alan-medium, `speed` 0.7–1.5) as MP3 or WAV; up to 6 000 characters at a time from a .txt, .md or .html. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
