Chatterbox API
resemble-ai/chatterbox-v1/text-to-speech6크레딧부터 /회Resemble AI의 오픈소스 Chatterbox text-to-speech는 영어 최대 1,000자를 24 kHz 모노 WAV로 읽습니다. 내장 목소리 또는 보낸 짧은 레퍼런스 클립의 목소리를 쓰며 표현력과 변화를 조절합니다.
POST /jobs/createTask에서 모델 이름을 resemble-ai/chatterbox-v1/text-to-speech(으)로 지정하면 호출할 수 있습니다. 6크레딧/회부터(US$0.06). 새 계정에는 30크레딧이 지급되니 Playground에서 먼저 무료로 써 보세요.
