Hugging Face and Cerebras bring Gemma 4 to real-time voice AI
Hugging Face and Cerebras jointly demonstrated a real-time speech-to-speech architecture: voice input is transcribed by Nvidia's Parakeet, reasoning is handled by Google DeepMind's Gemma 4 31B running on Cerebras, and speech output is synthesized with Alibaba's Qwen3TTS.
Why it matters: The article lays out a complete open-source speech-to-speech stack with components at each layer, so developers can build or swap parts of their own real-time voice AI pipeline.
