Hugging Face and Cerebras bring Gemma 4 to real-time voice AI

Hugging Face and Cerebras demonstrated a modular speech-to-speech pipeline for real-time voice AI.

The setup uses Nvidia Parakeet for speech recognition, Gemma 4 on Cerebras for language inference, and Alibaba Qwen3TTS for voice output.

By splitting the stack across specialized models and hardware, the system aims to cut latency and keep response times more consistent.

Lower, steadier latency could make voice assistants and robots feel more natural, responsive, and reliable.
