pipecat/changelog/3732.changed.md

• Improved audio context management in AudioContextTTSService by moving context ID tracking to the base class and adding reuse_context_id_within_turn parameter to control concurrent TTS request handling.
  • Added helper methods: has_active_audio_context(), get_active_audio_context_id(), remove_active_audio_context(), reset_active_audio_context()
  • Simplified Cartesia, ElevenLabs, Inworld, Rime, AsyncAI, and Gradium TTS implementations by removing duplicate context management code
