acoustic analysis of speech is a powerful, noninvasive, and cost effective tool to study different aspects of motor speech disorders such as the dysarthria associated with pd. in this presentation we will discuss the rationale for using acoustic analysis, its advantages and disadvantages, and methods to overcome these disadvantages. as an example, we will address the use of vowel space area (vs...

this article addresses the perceptual correlates of compensatory lengthening in persian. in a perception experiment, duration, spectral tilt measurements h1-h2 and h1-f1 and f0 were varied in several steps based on the results from a production experiment (sadeghi, 2007). subjects were asked to identify the tokens involving vowel length. results revealed that duration is the most reliable perce...

Background The aphasiological literature has traditionally distinguished between anterior aphasia, associated with non-fluent speech, characterized by phonetic distortions arising from a disruption at the motor level of encoding, and posterior aphasia, characterized by fluent speech with phonological errors, due to a deficit at a higher level. However, these studies focused predominantly on con...

this study was an attempt to investigate the effect of vowel-recognition training on beginner and advanced iranian esl learners. a total of 36 adult iranian esl learners (18 advanced and 18 beginners) who were students of various majors at memorial university (mun) were recruited for the study. advanced participants had the experience of living in canada for at least three years while beginners...

In this paper we analyse and compare a low dimensional linguistic representation of vowels with high dimensional prototypical vowel templates derived from a native Australian English speaker. We further perform the same analysis on Lebanese and Vietnamese accented English to investigate how di erences due to accents impact on such a representation. In a low dimensional linguistic representation...

A visual speech training aid for persons with hearing impairments has been developed using a Windows-based multimedia computer. The training aid provides real time visual feedback as to the quality of pronunciation for 10 steady-state American English monopthong vowels (/aa/, /iy/, /uw/, /ae/, /er/, /ih/, /eh/, /ao/, /ah/, and /uh/). This training aid is thus referred to as a Vowel Articulation...

The relationship between vowel formants and the second subglottal resonance (Sg2) has previously been explored in English, German, Hungarian and Korean. Results from these studies indicate that vowel space is categorically divided by Sg2 and that Sg2 correlates well with standing height. One of the goals of this work is to verify if the above findings hold true in Mandarin as well. The correlat...

PURPOSE We investigated the contribution of vowel space, articulation rate, maximum utterance length, and language skills to intelligibility in 30-36 month old children with CP. We also examined differences among variables for 3 subgroups of children with CP and a small group of typically developing (TD) children. METHOD Nineteen children with CP and 5 TD children provided speech samples, and...
