Speech disorder exacerbates when negative affect is aroused in patients with schizophrenia. However, little is known about the effects of positive affect on speech disorder. A well-validated laboratory procedure was used to determine whether arousal of positive affect would modulate speech disorder in 57 stable outpatients with schizophrenia and 48 community controls. Overall, the level of spee...

It is claimed here that experimental evidence about human speech processing and the richness of memory for linguistic material supports a distributed view of language where every speaker creates an idiosyncratic perspective on the linguistic conventions of the community. In such a system, words are not spelled in memory of speakers from uniform letter-like units (whether phones or phonemes), bu...

communication, cognition, language, and speech are interrelated and develop together. it should come as no surprise to us that the key to intervention with deaf children is to establish, as early as possible, a functional communication system for the child and the parents. early intervention programs need to be multidisciplinary, technologically sound and most important, it should take cognizan...

Speech production errors characteristic of dysarthria are chiefly responsible for the low accuracy of automatic speech recognition (ASR) when used by people diagnosed with it. The results of the small number of speech recognition studies, mostly conducted by assistive technology researchers, are a testimony to this statement. In the engineering community, substantial research has been conducted...

Abstract The existence of a shared constraint hierarchy is one the criteria that defines and delimits speech communities. In particular, women men are thought to differ only in their rates variable usage, not constraints governing variation; is, typically considered belong same community. We find early twentieth century Southland, New Zealand, had different hierarchies for rhoticity, with commu...

A statistical parametric speech synthesis system based on hidden Markov models (HMMs) has grown in popularity over the last few years. This system simultaneouslymodels spectrum, excitation, and duration of speech using context-dependent HMMs and generatesspeechwaveforms from the HMMs themselves. Since December 2002, we have publicly released an open-source software toolkit named HMM-based speec...

Quantitative analyses of large data sets make use of both linguistic and sociological categories in sociolinguistic studies. While the linguistic categories are generally well-defined and there are sufficient tokens for further definition based on mathematical manipulation, the social characteristics such as socioeconomic class or ethnicity are neither. The familiar problem of grouping speakers...

The notion of the speech community has been one of the key concepts in sociolinguistics since its beginning, and yet at the same time remains one of the least satisfactory. This paper examines data from urban Jamaican Creole to shed light on it, in the process taking into account problems that have been raised by other Caribbean creolists in dealing with what Lawrence Carrington has aptly dubbe...

Designing a machine that is capable for understanding human speech and responds properly to speech utterance or spoken language has intrigued speech research community for centuries. Among others, one of the fundamental problems to building speech recognition system is acoustic noise. The performance of speech recognition system significantly degrades in the presence of ambient noise. Backgroun...
