    late-night-voice-note

    The voice-note script in Chatterbox's built-in voice at the default settings. With no reference clip it is Chatterbox's own English voice; the sliders change how it performs, not who it is.

  • 0:00 / –:––
    boss-fight-taunt

    A game taunt with exaggeration at 0.8 and temperature at 0.9 for a bigger, more varied delivery. The laugh is written as "Ha!" because tags would be read aloud.

    • 0.8

    storm-cabin-chapter
