## Default AI voice changed to ElevenLabs "Mark"

AI agents that don't specify a voice now speak with ElevenLabs' "Mark", a higher quality voice
included in the regular AI agent price. The default voice can change over time, so applications
that need a specific voice should set one explicitly.

Set a voice in the [Server SDKs](/docs/server-sdks/guides/voice-language) or with
[`voice` strings in SWML](/docs/swml/reference/calling/ai/languages#use-voice-strings),
and [browse and audition available voices](/docs/platform/voice/tts).
