Lip-synchronization: a method without the use of visemes

Blog Article

In the present article we describe a simplified method to resolve the problem of lip synchronization with a previously recorded audio file.The algorithm receives as input the audio file, Bed Accessories in a standard format (WAV) and returns as result a text file that contains average amplitude values corresponding to a predefined fraction of a second.In order to achieve the synchronization, the values such defined Grill / Top Oven Element are correlated with lip animation sequences.The adopted solution allows an automatic production process that is, on one hand, the analysis of an arbitrary audio file recorded by a user and, on other hand, the association of the file with a sequence of animation files.

The method was successfully employed in a large scale educational project in Mexico.
