Investigation on human speaker identification enables us to know the indexical cues to speakers, and it may consequently lead to the effective acoustical parameters that can be used for forensic speaker recognition. It is known that speaker individuality interacts with the phonological or linguistic information contained in speech signals. As proof, the accuracy of perceptual speaker identifica...

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...

BACKGROUND There are conflicting reports in the research literature of the literacy outcome of children with speech disorder. The link between phonological awareness and literacy in typically developing and literacy delayed children is well established, but there is less research specifically into children with an isolated speech disorder (i.e. with age-appropriate language skills). There is a ...

When underwriting individuals with aortic aneurysms, the following factors are used in risk selection: location, initial size, stability or velocity of change in size and co-morbid impairments. Treatment options based on clinical and ultrasonic findings are either surveillance or surgical resection. A recent study examined the 8-year outcome of early-surgery vs surveillance in small (4.6 cm) ao...

The effect of division of attention between the evaluation of multichannel audio quality degradations and involvement in a visual task (playing a computer game) was investigated. Time-variant impairments (drop-outs) were used to provide degradations in audio quality. It was observed that involvement in a visual task may significantly change the results obtained during the evaluation of audio im...

The effects of phonotactic constraints (i.e., the status of a sound as correctly or incorrectly articulated) and phonotactic probability (i.e., the likelihood of a sound sequence) on lexical acquisition have been investigated independently. This study investigated the interactive influence of phonotactic constraints and phonotactic probability on lexical acquisition in 3 groups of children: chi...

Prosody in speech is manifested by variations of loudness, exaggeration of pitch, and specific phonetic variations of prosodic segments. For example, in the stressed and unstressed syllables, there are differences in place or manner of articulation, vowels in unstressed syllables may have a more central articulation, and vowel reduction may occur when a vowel changes from a stressed to an unstr...

A TWO -PHASE PROJECT CONCERNED WITH THE EFFECTIVENESS OF SPEECH THERAPY WITH EDUCABLE MENTALLY RETARDED (EMR) CHILDREN IN A PUBLIC SCHOOL SETTING HAD TWO OBJECTIVES -TO ASSEMBLE A REASONABLY COMPLETE PICTURE OF ARTICULATION OF EDUCABLE MENTALLY RETARDED CHILDREN AND TO DETERMINE. THE VALUE OF SPEECH THERAPY TO EMR CHILDREN WITH ARTICULATION DEFICIENCIES. THE HEJNA ARTICULATION TESTS AND A SPEEC...

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...

This article describes a school-based telehealth service delivery model and reports outcomes made by school-age students with speech sound disorders in a rural Ohio school district. Speech therapy using computer-based speech sound intervention materials was provided either by live interactive videoconferencing (telehealth), or conventional side-by-side intervention. Progress was measured using ...
