MiniMax Speech-2.6-turbo Async Long TTS
MiniMax’s high-definition text-to-speech model, Compared to Speech 02 released in May, Speech 2.6 has three major breakthroughs: stronger multilingual expressiveness, more accurate voice replication, and broader coverage with 40 languages.
Best suited for long-form text-to-speech generation, such as entire books. Task queue times may be longer. For short sentence generation, voice chat, or online social scenarios, we recommend using synchronous TTS.
