The presentation concerns the evaluation of a temporal method for tracking cycle lengths in voiced speech. The speech cycles are detected via the saliences of the speech signal samples. The method does not request that the signal is locally periodic and the average period length known a priori. The cycle length extraction is applied to the analysis of dysphonic speakers affected by amyotrophic ...

Measuring the intelligibility of disordered speech is a common practice in both clinical and research contexts. Over the years various methods have been proposed and studied, including methods relying on subjective ratings by human judges, and objective methods based on speech technology. Many of these methods measure speech intelligibility at the speaker or utterance level. While this may be s...

Speech production assessment in disordered speech relies on tests such as intelligibility and/or comprehensibility tests. These tests are subjective and time-consuming for both the patients and the practitioners. In this paper, we report on the use of automatically-derived pronunciation scores to predict comprehensibility ratings, on a pilot development corpus comprised of 120 utterances record...

The Mackworth wide-angle reflection eye camera was used to record the position of the gaze on a display of 16 white symbols. One of these symbols changed to red after 30 sec, remained red for a minute of testing, and then became white again. Ten aphasic children (aged 5-9) were compared with 10 normal children matched for sex and age. The normal children looked immediately at the red circle, an...

Centralization of vowel formants has been associated with reduced intelligibility in healthy speakers and those with motor speech disorders [1-3]. Hence, estimations of speakers’ vowel space area (VSA) provide a promising avenue for assessing speech motor control. However, VSA measurements have traditionally demonstrated limited success in distinguishing healthy and disordered speech [1, 3]. On...

In this paper we will consider a widely attested process: LIQUID-GLIDE ALTERNATION, a phenomenon that can be observed in many areas of phonological research, such as studies of disordered language, historical sound changes and nonpathological speech errors and also in child language. You can see examples of this process in first language acquisition data from different languages in (1). Liquids...

The objective of the presentation is to report experiments involving the automatic classification of disordered connected speech into multiple (modal, moderately hoarse, severely hoarse) categories. Support vector machines, used for the classification, have been fed with temporal signal-to-dysperiodicity ratios, the first rahmonic amplitude as well as mel-frequency cepstral coefficients. The si...
