Description

The Grok Voice Agent API allows developers to create advanced voice agents with industry-leading speed and intelligence. Built entirely in-house by xAI, the voice stack includes custom models for audio detection, tokenization, and speech generation. This deep control enables rapid performance improvements and ultra-low latency responses. Grok Voice Agents support dozens of languages with native-level fluency and can switch languages mid-conversation. The API consistently outperforms competing voice models in human evaluations for pronunciation and prosody. Real-time tool calling and live search across X and the web are supported. Developers can integrate custom tools to enable dynamic task execution. The API follows the OpenAI Realtime specification for easy adoption. Pricing is a flat per-minute rate, making costs predictable at scale. The Grok Voice Agent API is designed for production-ready voice applications.

Description

A PolyAI voice assistant can have a natural conversation with customers for as long as it takes to solve their problem. Your customers can speak as they wish, without having to guess keywords. In the past, building a voice assistant meant spending months gathering thousands of training data. No additional training data is required for any use case. Our technology is pre-trained in billions of natural conversations. Our voice assistants are able to learn new languages quickly while maintaining the agent behavior, business logic and voice of your brand so that all customers are served equally. We are so confident in the ability of our voice assistants to scale that we don’t charge for maintenance.
