MiniMax Speech-02-HD

MiniMax Speech-02-HD is the high-definition variant of MiniMax's Speech-02 text-to-speech model, released in May 2025. Part of MiniMax's autoregressive Transformer-based TTS lineup, the HD variant prioritizes maximum audio fidelity for voiceovers, audiobooks, and other premium voice applications. The broader MiniMax TTS platform is frequently cited for best-in-class Chinese naturalness, with around 300 voices, voice cloning, and OpenAI-compatible API access.

Speech-02-HD sits between the older Speech-01 generation and the newer speech-2.6 and 2.8 flagship series that MiniMax has since rolled out, so buyers should confirm which generation their provider serves. Community integrations reference the model id speech-02-hd across MCP tools, SDKs, and Replicate deployments. Pricing is usage-based at roughly $0.10 per thousand characters through MiniMax's own API, with third-party aggregators listing it near $125 per million characters.
