Building natural-sounding voice agents requires a multi-model pipeline

By PulseAugur Editorial · [1 sources] ·

Building a natural-sounding voice agent for phone calls involves more than just speech-to-speech translation. The process requires a pipeline of smaller models to handle listening, determining when to speak, formulating a response, and speaking while allowing for interruptions. This approach, exemplified by the 'Alex' agent for negotiating freight rates, prioritizes a text-based intermediate step to ensure critical information like pricing is validated by code before being spoken.
