How Does HeyGen AI’s Dubbing Technology Work?

HeyGen AI’s dubbing technology works by using a combination of natural language processing (NLP) and deep learning techniques to generate high-quality audio and lip-sync for the AI avatars. The process involves the following steps:

• The user selects an AI avatar from HeyGen AI’s library or uploads their own photo or video to create a custom avatar.

• The user types or uploads a script in their preferred language and chooses a voice from HeyGen AI’s collection of over 300 voices in 40 languages.

• The user can also adjust the voice parameters, such as pitch, speed, tone, emotion, etc., to suit their needs and preferences.

• HeyGen AI’s NLP engine analyzes the script and converts it into phonetic symbols that represent the sounds of the language.

• HeyGen AI’s deep learning engine synthesizes the audio by using a neural network that mimics the human vocal tract and produces natural and realistic speech.

• HeyGen AI’s lip-sync engine matches the audio with the facial movements of the AI avatar by using a neural network that learns from thousands of hours of real human speech and expressions.

• HeyGen AI’s video generator combines the audio and lip-sync to create a seamless and synchronized video output.
