Improving acoustic-to-articulatory inversion by using hypercube codebooks

Slim Ouni, Yves Laprie

This paper presents an articulatory codebook construction method which gives a good space coverage with a limited number of points. We represent the articulatory space by hypercubes. Therefore the articulatory space is decomposed into regions represented by few number of points. We de- scribe our interpolation method to retrieve points from the hypercube and the inversion method based on the same inter- polation method. The advantage of the codebook and the in- version method is its robustness with respect to articulatory- to-acoustic mapping non-linearity problems.
