Fixie Voice

Ultravox Realtime (from Fixie.ai): The multimodal LLM platform that processes speech directly, bypassing ASR for fast, natural, real-time voice AI.

Fixie Voice is powered by the Ultravox Realtime platform: a managed service built on the open-source Ultravox Speech Language Model (SLM). This is a next-generation, multimodal LLM designed for real-time, human-like conversation. It eliminates the traditional Automatic Speech Recognition (ASR) step, processing speech directly as embeddings for superior speed and accuracy. This direct-to-LLM approach ensures faster, more consistent response times than legacy component systems. Ultravox Realtime is engineered for high-volume, enterprise-grade deployments, successfully handling thousands of concurrent calls with a focus on scalability and security.
