MiniMax

MiniMax Speech provides powerful text-to-speech APIs designed for voice AI applications. The Speech model family includes both high-definition and turbo variants optimized for different use cases—Speech HD for production-quality audio and Speech Turbo for low-latency real-time applications.

Key capabilities relevant to voice AI include streaming audio output for responsive conversational experiences, emotional voice control for natural-sounding interactions, and support for 40+ languages to serve global audiences. The models support voice cloning functionality, enabling custom voice experiences, and maintain high-quality prosody and natural intonation across different content types.

MiniMax's T2A (Text-to-Audio) API supports both synchronous and WebSocket-based streaming interfaces, making it well-suited for voice chat, online social interactions, and real-time voice assistant applications where latency matters.

Vapi and MiniMax work together to bring high-quality, multilingual text-to-speech capabilities to voice AI applications. Through this integration, Vapi developers can leverage MiniMax Speech models to power conversational AI agents with natural-sounding voices across 40+ languages.

The integration enables Vapi-powered voice applications to utilize MiniMax's streaming TTS capabilities for responsive, real-time conversations. Developers can choose between MiniMax's HD models for premium audio quality or Turbo models when minimizing latency is the priority. MiniMax's emotional voice control allows voice agents built on Vapi to deliver more expressive, human-like interactions that adapt tone and style based on conversational context.

This partnership expands voice options available to Vapi developers, particularly for applications serving multilingual audiences or requiring custom voice profiles through MiniMax's voice cloning capabilities.
