Voice

Overview

Inworld Studio has a variety of AI voices to choose from to fit your character, including tools to adjust and modulate these voices. This guide covers what these voice controls do and how to use them.

The Voice Tools

The Inworld Studio Voice tools consist of three main sections, Voice Attributes, Select Voice, and Customize Voice.

If you wish the test voice to say something different, you can enter a phrase into the Preview Voice Says… field.

Customize Voice

The Customize Voice section allows you to modulate your selected voice with either its Pitch or Talking Speed.

Note that only the legacy voices support Pitch. This option is greyed-out with the newer Inworld voices, as this setting is not needed due to the higher quality of these voices and their greater ability to self-modulate.

custom

  • Pitch controls the tone of your character’s voice. Lower values will lead to deeper voices, while higher values will lead to higher-pitched voices
  • Talking Speed controls the rate of your character’s speaking voice. Lower values make the character speak slower, while higher values make them speak faster.

Custom Voices

If none of the provided Inworld voices are the right fit for your character, please contact us to discuss working with voice actors and third-party integrations.
