Worked on the livekit/agents repository to enhance the Cartesia Text-to-Speech service by addressing streaming reliability issues. Focused on backend development using Python, the work involved increasing the buffered words count in tts.py from three to ten, directly reducing interruptions during TTS playback and improving the overall user experience. This targeted change aligned with Cartesia integration requirements and was implemented as a feature update, with thorough documentation provided in the associated commit. The approach demonstrated attention to streaming performance and reliability, leveraging backend engineering skills to optimize buffer management for real-time text-to-speech applications without introducing new bugs.
