MiniMax

MiniMax is an AI company building generative models across multiple modalities, with a focus that spans both language understanding and audio creation. Their rapid release cadence in early 2026—delivering several new models within just a few months—reflects…

MiniMax Speech-02 HD is the text-to-speech engine in MiniMax's catalogue, the "HD" variant tuned for high-fidelity audio output that prioritizes clarity and naturalness over raw speed. Released in April 2026, it converts written text into spoken voice, making it a fit for narration, voiceovers, audiobooks, and conversational agents where audio quality matters.

Within MiniMax's lineup, Speech-02 HD is the lab's dedicated speech-synthesis offering, sitting alongside its text-generation line — including MiniMax M3 and MiniMax M2.7 — and its music-generation models such as MiniMax Music 2.6. It is the current incumbent of the Speech HD line with no newer same-family successor, so it represents MiniMax's latest dedicated TTS work on the platform.

In practice, the model is best reached for when you need polished, listenable speech output rather than draft-quality audio: think product narration, accessibility readouts, character voices, and any pipeline that pairs generated or supplied text with a spoken delivery layer.
