AI BriefingHugging Face-Cerebras Unveil Real-Time Voice AI Pipeline
Key point
Hugging Face and Cerebras have introduced ultra-low-latency real-time speech-to-speech technology powered by Gemma 4.
Details
Hugging Face and Cerebras have unveiled an ultra-low-latency real-time voice AI pipeline to close the gap between model quality and response speed. This technology features a modular architecture that combines various models from the open-source ecosystem.
The entire system operates as the following Open Stack structure:
- Speech Recognition (ASR): Nvidia's Parakeet
- Language Model (LLM): Google DeepMind's Gemma 4 31B (using the Cerebras inference engine)
- Speech Synthesis (TTS): Alibaba's Qwen3TTS
In particular, Cerebras's high-speed inference engine dramatically reduces the language model's response time, providing a natural user experience where the flow of conversation is not interrupted. This technology is also being used in the voice interface of the Reachy Mini robot, which is currently deployed in over 9,000 robots, enabling real-time interaction between robots and humans.
