A talking avatar is a technology that creates a video with synchronized lip articulation to an audio track. You upload a portrait photo and an audio recording (speech, singing, voiceover), and the SadTalker algorithm generates a video where the person in the photo 'speaks' your audio file with realistic lip movement, facial expressions, and micro head movements.
The feature of the technology is that it works with any portraits — not only real people but also drawn characters, anime heroes, historical portraits. For the best result, you need a clear frontal face photo with a neutral expression and minimal head tilt. The quality of the audio track directly affects the result: a clean recording without background noise provides clearer synchronization.
The finished video is saved in MP4 format and is suitable for embedding in presentations, websites, educational materials, or social media posts.
