conclusions the results suggested that pa skills in children with phonological disorders are affected by error type. we also found the type of errors that can play a more effective role in pa investigations as compared to pcc. the results also showed that children with cap require special attention. results the cap group showed significant difference with the nd group in alliteration (p = 0.001...

The diagnosis of speech disorders requires not only audio but also visual analysis. The speaker often performs many articulation moves, e.g.: a movement of mouth without emitting sound. Therefore a computer program was developed for simultaneous analysis of several elements in conjunction with the digital recording of a person’s speaking face. These elements are: sound, a spectrogram picture an...

Introduction Speech articulation disorders affect the intelligibility of speech. Studies on therapeutic models show the effectiveness of the communication treatment. Objective To analyze the progress achieved by treatment with the ABAB-Withdrawal and Multiple Probes Model in children with different degrees of phonological disorders. Methods The diagnosis of speech articulation disorder was dete...

A companion paper describes three extensions to a classification system for paediatric speech sound disorders termed the Speech Disorders Classification System (SDCS). The SDCS uses perceptual and acoustic data reduction methods to obtain information on a speaker's speech, prosody, and voice. The present paper provides reliability estimates for the two perceptual methods (narrow phonetic transc...

Objective: The aims of the present study was to develop and validate a quick repetition test using familiar, culture-based words for the assessment of the Farsi speaking children suffering from Speech Sound Disorders (SSD). Method: The study population was divided into two groups, including 419 participants without any clinical signs of speech impairment and 36 cases with SSD. Psychometric pro...

Purpose: The purpose of the study was to determine whether distinct subgroups of preschool children with speech sound disorders (SSD) could be identified using a subgroup discovery algorithm (SUBARP). Of specific interest was finding evidence of a subgroup of SSD exhibiting performance consistent with atypical speech motor control. Method: Ninety-seven preschool children with SSD completed spee...

This paper pinpoints some of the problems faced when a computer text production model (COMMENTATOR) is to produce spontaneous speech, in particular the problem of chunking the utterances in order to get natural prosodic units. The paper proposes a buffer model which allows the accumulation and delay of phonetic material until a chunk of the desired size has been built up. Several phonetic studi...
