In this paper a method to analyze pathological speech signal using wavelet transform is suggested. Pathological speech signal is commercially available pathological voice database and analyzed by the suggested method. Normal speech signal is also from the same database and analyzed as well. Then the results are compared to find the differences between normal and pathological speech. Three level...

To study the effects of clinicians' slow rate on the speech of children who stutter with and without a concomitant phonological disorder, an A-B-A-B single case design was used with six clinician-child dyads, where B = Clinician's slow speech rate model. Two boys and one girl, aged 49-54 months, stuttering with disordered phonology (S + DP), were compared to three boys aged 42-50 months, stutte...

Automatic disorder recognition in speech can be very helpful for the therapist while monitoring therapy progress of the patients with disordered speech. In this article we focus on prolongations. We analyze the signal using Continuous Wavelet Transform with 18 bark scales, we divide the result into vectors (using windowing) and then we pass such vectors into Kohonen network. Quite large search ...

A powerful pitch estimation algorithm called SWIPE has been developed for processing speech and music. SWIPE is shown to outperform existing algorithms on several publicly available speech and musical instrument databases, and a disordered speech database, reducing the gross error rate by 40%, relative to the best competing algorithm. In short, SWIPE estimates the pitch as the fundamental frequ...

We present the first prototype of a new optoelectronic instrument for the combined real-time measurement of the tongue contour in the mid-sagittal plane, the contact pattern between the tongue and the palate, and the position of the lips. The instrument consists of a thin acrylic pseudopalate with embedded contact sensors, as for electropalatography, and optical distance sensors to measure tong...

Some studies have found that the speech of certain schizophrenia patients becomes more disordered in stressful laboratory situations. It is unknown, however, whether affective reactivity of speech is associated with stress responsiveness of symptoms in the real world. This study examines whether language-reactive patients report more stress-related impairments in work functioning than language-...

IDPs (intrinsically disordered proteins) are common in eukaryotic genomes and have regulatory roles. In the cell, they are disordered, although not completely random. They bind weakly, but specifically, often remaining partially disordered even when bound. Whereas folded globular proteins have 'executive' roles in the cell, IDPs have an essential administrative function, making sure that the ex...

The objective is to analyze vocal dysperiodicities in connected speech produced by dysphonic speakers. The analysis involves a speech variogram-based method that enables tracking instantaneous vocal dysperiodicities. The dysperiodicity trace is summarized by means of the signal-todysperiodicity ratio, which has been shown to correlate strongly with the perceived degree of hoarseness of the spea...

In this paper, we report on a study with the aim of automatically detecting phoneme-level mispronunciations in 32 French speakers suffering from unilateral facial palsy at four different clinical severity grades. We sought to determine if the Goodness of Pronunciation (GOP) algorithm, which is commonly used in Computer-Assisted Language Learning systems to detect learners’ individual errors, co...
