MiniMax

MiniMax TTS delivers highly expressive and emotionally rich Chinese voices with advanced prosody control. Its speech models are known for natural-sounding intonation that goes beyond monotone synthesis. Ideal for applications where voice personality and emotional expressiveness matter — such as virtual companions or customer-facing bots.
