Also, it can be used to help the people with impaired-hearing. We use HMMs (hidden Markov models) to convert audio signals to a sequence of visemes. In this paper, we compare two approaches in using HMMs. In the first approach, an HMM is trained for each viseme, and the audio signals are directly recognized as a sequence of visemes.

In this paper, the inversion of a joint Audio-Visual Hidden Markov Model is proposed to estimate the visual information from speech data in a speech driven MPEG-4 compliant facial animation system. The inversion algorithm is derived for the general case of considering full covariance matrices for the audio-visual observations.

Baum-Welch hidden Markov model inversion for reliable audio-to-visual conversion. Abstract:In this paper, a novel audio-to-visual conversion method is presented. Many multimedia applications, such as videophones, videoconferencing, man-machine interface, language dubbing, character animation in virtual reality, etc., require techniques for …

tic noise perturbation. The audio-visual speech recognition sys-tem presented in this paper introduces a novel audio-visual fusion technique that uses a coupled hidden Markov model (HMM). The statistical properties of the coupled-HMM allow us to model the state asynchrony of the audio and visual observations sequences
