Extraction of vocal-tract system characteristics from speech signals

Extraction of vocal-tract system characteristics from speech signals

We propose methods to track natural variations in the characteristics of the vocal-tract system from speech signals. We are especially interested in the cases where these characteristics vary over time, as happens in dynamic sounds such as consonant-vowel transitions. We show that the selection of appropriate analysis segments is crucial in these methods, and we propose a selection based on est...

Understanding of vocal tract pathology using speech signals analysis

In the present work we introduce a new approach to pathological speech processing methods and recognition of various speech pathologies. We no longer attempt to recognise forms of pathological speech deformations, because it is impossible to show any compact template of a normal speech signal (as reference) and it is also impossible to show a standard form of any deformation. Almost any sample ...

Silent-speech enhancement using body-conducted vocal-tract resonance signals

Semi-automatic extraction of vocal tract movements from cineradiographic data

Since high speed X-ray films still provide the best dynamic view of the entire vocal tract, large existing databases have been preserved and are available for the speech research community. We propose a new technique for facilitating the extraction of the vocal tract shape and the movements of the articulators from complete sequences of these databases. The method was first developed for the ex...
