MiniMax Speech-2.5
MiniMax's flagship TTS in HD and Turbo flavors: 40+ languages, 300+ voices, and cloning-grade fidelity.
About
MiniMax Speech-2.5 is the Shanghai startup's flagship text-to-speech model, launched August 7, 2025 as the follow-up to May's Speech-02. It comes in HD and Turbo variants, covers more than 40 languages with a library of 300-plus prebuilt voices, and MiniMax pushes it especially for voice cloning fidelity and cross-language accent retention — its launch demos included reproducing the Queen of England's cadence in both English and Italian. Third-party API hosts describe Turbo as the real-time option and HD as the quality option.
MiniMax's own pricing lists the current generation around $60 per million characters for Turbo and $100 for HD, with pay-as-you-go and subscription paths; partner hosts show slightly different numbers, so the pricing page is the source of truth. The company claims world-leading multilingual expressiveness, which is provider marketing rather than an independently verified benchmark. Access is through MiniMax's text-to-audio API with WebSocket streaming.

Benchmarks
No independent published benchmarks for the 2.5 series; MiniMax's 'world's strongest speech model' positioning is provider-claimed
Provider-reported unless a source says otherwise. Benchmarks are marketing-adjacent by nature — treat them as directional.
