analyze_speech Read-only

Limits: up to 120 seconds and 10 MB; mp3, m4a/mp4, wav, webm, ogg or flac; at least 30 spoken words. Pass audioUrl (public https) or audioBase64. Free: 1 analysis a day per network; a try that fails on our side does not count, up to 3 tries a day. Audio is deleted once the response is sent.
