Speech speed is measured and displayed with our specific algorithm TEMAX (Temporal Evaluation and Measurement Algorithm by KS). The TEMAX-gram, a sonagraphic output of speech envelope, the DFT using a 1-second window is convenient to set off isosyllabic characteristics. For Japanese traces 2 dark bars, called rhythmic formants: RF1 and RF2: the first one,(More)
A prosodic labeling support system has been developed. Large-scale prosodic databases are strongly desired for years, however, the construction of databases depend on hand labeling, because of the variety of prosody. We aim at not automating the whole labeling process, but making the hand labeling work more efficient by providing the labelers with the(More)
In this paper, we propose a new consonant recogmtIOn method which integrates two stochastic method: discriminant analysis and HMM (Hidden Markov Models). Discriminant Analysis is effective to analyze local patterns around the reference-point of a consonant such as a burst point. This method, however, is based on the assumption that the reference-point is(More)
A very detailed segmentation of prosodic phrase was carried out in order to construct a Japanese prosodic database. Boundaries correspond to junctures between phrases including C|C and V|V clusters. The "prosodic phrase" we introduced as a unit of the segmentation was defined and regarded as a unit of language speech perception. For the exact segmentation,(More)
Auditory models reverse processing techniques would have very useful applications in speech perception and auditory models evaluation. This paper examines how we can be benefit an Inner Hair Cell (IHC) model as a compression and envelope detection section, in the cochlear model inverse processing. Our proposed inversion method, combines the reverse of the(More)
