Audiovisual-to-articulatory inversion
It has been shown that acoustic-to-articulatory inversion, i.e. estimation of the articulatory configuration from the corresponding acoustic signal, can be greatly improved by adding visual features extracted from the speaker’s face. In order to make the inversion method usable in a realistic application, these features should be possible to obtain from a monocular frontal face video, where the...
متن کاملSynthesis of fricative consonants by audiovisual-to-articulatory inversion
We present here results of audio-visual to articulatory inversion for French fricatives embedded into VCVs. The inversion technique is evaluated using both experimental and synthetic data. The final synthesis is assessed by a perceptual categorisation test. Synthetic stimuli have similar scores as natural ones.
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...
متن کاملFormant trajectories for acoustic-to-articulatory inversion
This work examines the utility of formant frequencies and their energies in acoustic-to-articulatory inversion. For this purpose, formant frequencies and formant spectral amplitudes are automatically estimated from audio, and are treated as observations for the purpose of estimating electromagnetic articulography (EMA) coil positions. A mixture Gaussian regression model with mel-frequency cepst...
