About this model

Fish Audio S1 is a multilingual text-to-speech model capable of generating highly expressive speech. It utilizes a fixed vocabulary of preset emotion tags enclosed in parentheses at the beginning of sentences (e.g., sound effects, tone markers) to steer the emotion and delivery of the generated voice.
