List Cartesia voices

Changed on

List the public Cartesia voices available for a personality's voice_id, with each voice's language, gender, description and preview URL. Use this to pick a voice with the accent you want to test: a personality's accent comes from its voice. Cartesia publishes no accent label, so judge accent from the voice's name and description, or use personalities_elevenlabs_voices when you need a labelled accent. Filter with language (e.g. en, es).

Pair the id you pick with provider: "cartesia" and voice model sonic-3.5.

The catalog is not a hard limit: if no listed voice has the accent, language or timbre a test needs, Cekura can add one on request — point the user at support@cekura.ai or their dedicated Slack support channel rather than reporting the accent as unsupported.

accentstring

Read-only label describing the accent of this personality's voice, as reported by the voice provider. It is derived from voice_id and cannot be set directly: speech is synthesised from voice_id alone, so changing the accent of a personality means choosing a different voice. Empty when the provider publishes no accent for the voice.

background_noisestring required

Background noise

voice_modelstring required

Voice model name

voice_idstring

Voice ID Example: "TX3LPaxmHKxFdv7VOQHJ"

interruption_levelstring

Interruption level

speednumber

Speed of the voice

start_speaking_plannumber

Wait seconds before the bot starts speaking (float >= 0). Ignored if interruption_level is also set in the same request (preset takes precedence). Example: 0.7

voice_volumestring nullable

Speech volume of the testing agent (0.01 to 2.0, default 1.0). Works on every voice provider — it is amplitude scaling applied after synthesis, so it reaches far quieter levels than generation_config.volume, which is a Cartesia-native parameter limited to Cartesia's own 0.5-2.0. Setting this clears any generation_config.volume so the ratio is never applied twice. Send null to remove it. Example: 0.05 for a barely-audible caller.

effective_voice_volumestring

Read-only. The volume the call will actually play at: voice_volume if set, else a legacy generation_config.volume, else 1.0. Use this to populate a volume control.

patronus_settingsunknown
provider_agent_idstring

Provider agent ID Example: "assistant_123"

end_call_enabledboolean

Whether the end call is enabled
