Abstract(in English) | This paper presents a method for estimating the acoustic property of the vocal tract from the position of the articulatory organs, i.e., the jaw, lips, tongue, and soft palate. Our method transforms input articulatory position to the vocal tract spectrum on the basis of phoneme-dependent neural networks. The obtained phoneme-dependent spectra are then interpolated to estimate the tune course of the vocal tract spectrum for the given phonemic context. In addition, the weight in this spectral interpolation is determined on the basis of the distance in the articulatory domain between the input and phoneme-specific articulator positions. For training of these networks, the articulatory-acoustic data pairs taken for continuous utterances are used by taking the spectral interpolation into account. Experimental results showed that the average spectral error in our estimation method is 3.15 dB. |
