Multivariate analysis of frame-based acoustic cues of dysperiodicities in connected speech
نویسندگان
چکیده
Generalized variogram is used to extract vocal dysperiocities in disordered speech produced by dysphonic speakers. Both signal and dysperiodicity are passed through a filter bank and a segmental signal-to-dysperiodicity ratio is defined in each frequency band. Multivariate analysis is carried out to summarize the degree of perceived hoarseness. The predictor variables are the segmental signal-to-dysperiodicity ratios in the different bands. It is shown that high correlations are achieved by linear regression analysis of the segmental signalto-dysperiodiciy ratios in different non-overlapping frequency bands. Index Terms : disordered speech, multivariate analysis, generalized variogram, dysperiodicity estimation.

Assessment of vocal dysperiodicities in connected disordered speech
The aim of the presentation is to investigate acoustic analysis of connected speech by means of an average-equalized and energy-equalized variogram to extract vocal dysperiodicities. The variogram enables positioning a current and a lagged analysis frame in adjacent speech cycles to track inter-cycle dysperiodicities. Average and energy equalization of the analysis frames are options that make ...

Speech recognition is a subfield of artificial intelligence that develops technologies to convert speech utterance into transcription. So far, various methods such as hidden Markov models and artificial neural networks have been used to develop speech recognition systems. In most of these systems, the speech signal frames are processed uniformly, while the information is not evenly distributed ...

متن کاملGeneralized variogram analysis of vocal dysperiodicities in connected speech
A generalized variogram is used to track vocal dysperiodicities in connected speech, which are summarized by means of a signal-to-dysperiodicity marker. To evaluate the variogram-based analysis, signal-to-dysperiodicity estimates are correlated with scores obtained by means of perceptual ratings of the degree of hoarseness, which are based on comparative judgments of pairs of speech samples. Th...
