Unlike other voice-based systems, Ultravox integrates speech recognition directly, without relying on transforming speech into text. This makes Ultravox faster, more reliable, and more natural.
Ultravox
Understanding speech directly means there are fewer moving parts. This means much faster and much more consistent response times than the Legacy Component System.
Legacy Component Systems
The current industry standard is a cascaded pipeline of services strung together to give the illusion of a seamless experience. This means it's slower, more brittle, and unable to capture the nuances of human speech.
