Takes a text of up to 10,000 characters with simple markers
Takes a text of up to 10,000 characters with simple markers: [pause N] inserts N seconds of silence (up to 30), and a blank line inserts the paragraph pause you set. Every text part is spoken by a natural synthetic voice in one of seven languages, and the parts and pauses are joined exactly, so a breathing exercise or a dictation gets the gaps it needs. Returned are the audio file (MP3, Opus or WAV) and the start and end of every spoken part and pause. Speech by Deepgram with training opt-out.
