Step-by-Step Guide to Creating Dialogue

  1. Select Your Character

    Choose from the roster of Undertale characters, each with their unique text box style and sound effects. Popular choices include Sans, Papyrus, Toriel, and Flowey.

  2. Craft Your Dialogue

    Enter your custom text, keeping in mind the character's speech patterns and personality. For example, Sans uses lowercase and casual language, while Papyrus speaks in all caps with exaggerated expressions.

  3. Add Sound Effects

    Apply the character's signature voice sounds. The undertale text sound generator feature allows you to match the exact cadence and tone of each character.

  4. Adjust Timing and Pacing

    Fine-tune the text reveal speed and sound timing to match the character's speaking style. Slower for dramatic moments, faster for excited dialogue.
