+## 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](/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).
