Acoustic-to-articulatory inversion by analysis-by-synthesis using cepstral coefficients
This paper deals with acoustic to articulatory inversion of speech by using an analysis by synthesis approach. We used old X-ray films of one speaker to (i) the develop a linear articulatory model presenting a small geometric mismatch with the subject’s vocal tract mid sagittal images (ii) and design an adaptation procedure of cepstral vectors used as input data. The adaptation exploits the bil...
متن کاملAdaptation of cepstral coefficients for acoustic-to-articulatory inversion
Acoustic-to-articulatory inversion of speech signals via an analysisby-synthesis method requires the comparison of natural and synthetic speech spectra either indirectly via formant frequencies, or directly via cepstral coefficients. This paper investigates several strategies of cepstral adaptation (affine transformation of cepstral coefficients, bilinear or piecewise linear frequency warping) ...
متن کاملPronunciation analysis by acoustic-to-articulatory feature inversion
Second language learners may require assistance correcting their articulation of unfamiliar phonemes in order to reach the target pronunciation. If, e.g., a talking head is to provide the learner with feedback on how to change the articulation, a required first step is to be able to analyze the learner’s articulation. This paper describes how a specialized restricted acoustic-to-articulatory in...
متن کاملImproving acoustic-to-articulatory inversion by using hypercube codebooks
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 describe our interpolation method to retrieve points from the hypercube and the inversion method based on the same...
متن کاملAcoustic to articulatory inversion
The context of this work is speech analysis. The subject deals with acoustic-to-articulatory inversion, i.e. the recovery of the temporal evolution of the vocal tract shape from the signal. This topic is important because it is likely to give rise to applications in the domains of speech coding as well as second language learning. Acoustic-to-articulatory inversion relies on an analysis by synt...
