Background: Hypothyroidism may cause symptoms and disorders in different parts of the body which can lead to speech disorders. This research was done to recognize and identify speech disorders in patients with Hypothyroidism. Materials and methods: This descriptive study was done on 120 subjects with hypothyroidism, with T4 4mU/L. Members of the study team interviewed all subjects, performed a...

Background & Objective: Stuttering is a prevalent disorder in children and adolescents. Because attention is the only fuel resource for cognitive functions and the language have high cognitive functions, then it is possible that speech difficulties are related to attention deficit. The purpose of this study was to investigate the attentional demand of speech in children and adolescents with dev...

Introduction: Aging reduces the ability to understand speech in noise. Hearing rehabilitation is one of the ways to help older people communicate effectively. This study aimed to investigate the effect of vowel auditory training on the improvement of speech-in-noise (SIN) perception among elderly listeners.   Materials and Methods: This study was conducted on 36 elderly ...

Although, speech recognition systems are widely used and their accuracies are continuously increased, there is a considerable performance gap between their accuracies and human recognition ability. This is partially due to high speaker variations in speech signal. Deep neural networks are among the best tools for acoustic modeling. Recently, using hybrid deep neural network and hidden Markov mo...

Objective: This study was a basic investigation of the ability of concurrent speech segregation in hearing impaired children. Concurrent segregation is one of the fundamental components of auditory scene analysis and plays an important role in speech perception. In the present study, we compared auditory late responses or ALRs between hearing impaired and normal children. Materials & Methods...

Private speech utilization is accepted to have a critical role in the continuum of language acquisition. As a valuable device in studying learners’ talk during interaction, a language related episode (LRE) is any part of a dialogue where a student speaks about a language problem s/he comes across while completing a task. The present study investigated the role of private speech produced by Inte...

Quality of speech signal significantly reduces in the presence of environmental noise signals and leads to the imperfect performance of hearing aid devices, automatic speech recognition systems, and mobile phones. In this paper, the single channel speech enhancement of the corrupted signals by the additive noise signals is considered. A dictionary-based algorithm is proposed to train the speech...
