Overview

This node interacts with the Heygen API to perform various operations related to avatar videos and assets. Specifically, the 'List Voices' operation retrieves a list of all available voices from Heygen. This is useful for users who want to see which voices they can use for generating avatar videos or other voice-related features. Practical applications include selecting a voice for text-to-speech avatar videos or exploring voice options for content creation.

Use Case Examples

1. A user wants to generate a video with an avatar speaking a specific text and needs to choose a voice from the available options. They use the 'List Voices' operation to get the list of voices.
2. A content creator wants to explore different voice options provided by Heygen before generating videos or audio content.
