pipecat/changelog/4527.fixed.md

• Fixed a race in ElevenLabsTTSService where the periodic keepalive could be sent for a new turn's context before that context's voice_settings initialization message, causing ElevenLabs to close the WebSocket with a 1008 policy violation (voice_settings field must be provided in the first message ...). The keepalive now only targets a context once its context-init has been sent.
