With custom text to speech avatar, you can build a unique and natural-looking avatar for your product or brand by providing video recording data of your selected actors. If you also create a [custom neural voice](#custom-voice-and-custom-text-to-speech-avatar) for the same actor and use it as the avatar's voice, the avatar will be even more realistic.
