Errors

How Speechbase reports failures using RFC 7807 Problem Detail, and the error codes you should plan for.

Generate speech POST

Synthesizes the whole clip and returns raw audio bytes in a single response. Pass either `voiceId` (to use a saved Voice) or `model` + `voice` (inline), not both. Because the full clip is produced server-side, whole-clip params (`volumeDbfs`, `output` format conversion) are applied here. For low-latency provider streaming, use POST /v1/audio/speech/stream.
