Background and Objectives: Investigating the prevalence of speech and language disorders and the contributing factors can help determine the best treatment options suited to the needs of these patients. So far, no comprehensive study has been conducted on screening speech and reading disorders and problems in the structure and function of articulation organs (PSFAOs) in children in Mashhad City...

introduction: the every possible attempt in voice disorders assessment is to gather samples which represent individual s’ actual voice in the daily speech. the researchers have found that voice characteristics in reading a passage are closer to daily speech. making texts has been started since early 20th century. the lack o f suitable text in farsi language makes it difficult to conduct requisi...

An examination of Bark scale spectra of some 30'000 vowel nuclei from the Marsec corpus showed significant voice quality differences for sex and speech style. Of the two, speech style appeared to be the stronger predictor in multiple correlation analyses. Clustering further documented the effects of speech style, with hierarchical clustering grouping voice profiles of similar-sounding styles. S...

Voice over Internet Protocol (VoIP) is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line. Voice over Internet Protocol (VoIP) has led human speech to a new level, where conversation across continents can be much cheaper & faster. However, as IP networks are not designed for real-time applications, the network impai...

The great advantage of using a glottal source model in parametric speech synthesis is the degree of parametric flexibility it gives to transform and model aspects of voice quality and speaker identity. However, few studies have addressed how the glottal source affects the quality of synthetic speech. Here, we have developed the Glottal Spectral Separation (GSS) method which consists of separati...

communication disorder is a widespread disabling problems and associated with adverse, long term outcome that impact on individuals, families and academic achievement of children in the school years and affect vocational choices later in adulthood. the aim of this study was to determine prevalence of speech disorders specifically stuttering, voice, and speech-sound disorders in primary school s...

The performance of unreliable voice transmission (Voice over IP) over wireless links is measured not by the throughput but by the perceptual speech quality. The speech quality is impaired by packet losses, which are common on wireless links, and by high transmission delays. In this paper, we describe the design and implementation of a novel Speech Property Based Booster that improves the qualit...
