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 AI Agent SDK or with voice strings in SWML, and browse and audition available voices.
