List Agent Voices | SpeechifyAI API

List the curated voice catalogue available for voice agents. Matches the ai-api-agents VMS scope one-for-one, so the same slug set is accepted by POST/PATCH /v1/agents. Personal (cloned) voices are NOT included — they stay on GET /v1/voices. The JSON layout intentionally mirrors the TTS /v1/voices shape so a single voice picker can consume both endpoints. Returns the full set in a single response: bounded by the curated agent voice catalogue, so this list is intentionally not paginated.

Response headers

X-Request-IDstring

Unique identifier for this request, present on every response (2xx and non-2xx alike). If the caller sends an X-Request-ID request header the server echoes it back (sanitized and length-capped) so one logical request can be traced end-to-end; otherwise the server generates a fresh value. Log it on every response and quote it in support requests - it is the stable handle that ties your observation to Speechify’s server-side logs, and it matches the request_id field in the error envelope.
