The user has developed 'RealtimeVoiceChat,' an open-source system aimed at reducing latency in AI voice interactions to around 500ms. This tool facilitates natural and real-time voice conversations using audio chunk streaming over WebSockets and integrates technologies like Whisper for speech-to-text (STT) and Coqui XTTSv2 for text-to-speech (TTS). It is designed to work with local large language models (LLMs) and is particularly optimized for use with GPUs. Key features include interruptible conversations and smart turn detection to improve user experience. Feedback is being solicited for improvement and essential features.
