Create a personality

Changed on

Create a personality — the simulated caller your evaluators run as. A personality carries the caller's voice, language, speaking speed, interruption behavior, background noise and idle timing; an evaluator carries what that caller is trying to do. Evaluator instructions cannot override any of it, so a call-wide trait belongs here and nowhere else.

voice_id and provider decide how the caller actually sounds, including its accent — list the catalog with personalities_elevenlabs_voices or personalities_cartesia_voices (both filter by language) and pass an id from there. accent is a read-only label derived from that voice and cannot be set.

To reuse a predefined personality with one thing changed, fork it instead of building a new one: forks inherit every setting.

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

provider'11labs' | 'cartesia'

Provider of the voice
