Voice Options

The Voice tab allows you to define the personality of your assistant through tone, pitch, and background ambiance. You can choose from a range of high-quality voices and optionally add ambient sound for a more realistic effect. To access this section:
Build → Assistant → Select Assistant → Voice

​
Voice Configuration

Select the voice provider and voice profile you want your assistant to use.

​
Supported Providers

  • CallHQ (default, built-in voices)
Additional provider support (e.g., ElevenLabs, PlayHT) may be added in future updates.

​
Available Voices from CallHQ

​
Additional Configuration

​
Background Sound

You can add background sound to create a more immersive voice experience, such as:
  • Office ambiance
  • Cafe noise
  • Airport terminal
To use this, turn Background Sound on and provide a valid .mp3 or .wav URL in the input field. Example: https://example.com/callhq-ambient.mp3 This sound will loop softly behind your assistant’s voice.

​
Best Practices

  • Choose a voice aligned with your brand and use case (formal, friendly, regional).
  • Use background sound sparingly to avoid distraction.
  • Use the play button to preview each voice before saving.
Once your voice settings are finalized, click Save and test the assistant via chat or web call.
