Rule-based lip-syncing algorithm for virtual character in voice chatbot
Virtual characters changed the way we interact with computers. The
underlying key for a believable virtual character is accurate synchronization
between the visual (lip movements) and the audio (speech) in real-time. This
work develops a 3D…
