Inline tags control delivery at the token level. Insert them anywhere in `input`, and the model adjusts the surrounding speech. For example: ``` <|emotion:enthusiasm|>Welcome to the show! <|prosody:pause|>Let's get started! ``` Tags fall into four categories: * **emotion**: `<|emotion:…|>`, such as elation, fear, anger. * **style**: `<|style:…|>`, such as shouting, whispering. * **sound effects**: `<|sfx:…|>`, such as cough, sneeze. * **prosody**: `<|prosody:…|>`, including speed, pause, pitch, and expressiveness. Recommended usage: * Lead the turn with delivery tokens. Emotion, style, speed, pitch, and expressiveness tags set how the entire turn is delivered, so place them at the start of the input before any text. Positional tokens are the exception: `<|prosody:pause|>` and `<|prosody:long_pause|>` go exactly where the break should fall, and each `<|sfx:…|>` goes right before the sound it triggers. * Pair every sound effect with onomatopoeia. A `<|sfx:…|>` token works best when the matching written sound follows immediately, such as `<|sfx:laughter|>Haha`, `<|sfx:sigh|>Uh`, or `<|sfx:sneeze|>Achoo`. The written cue helps the model realize the sound effect.
