To provide alternatives to the widespread use of nonspeech oral motor exercises for childhood speech sound disorders, speech intervention approaches that have received the highest level of experimental scrutiny are reviewed. Efficacy research over the past decade is critically evaluated according to hierarchical systems for quality and credibility. High standards for adherence to experimental m...

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 ...

We report findings from two feasibility studies using automatic speech recognition (ASR) methods in childhood speech sound disorders. The studies evaluated and implemented the automation of two recently proposed diagnostic markers for suspected Apraxia of Speech (AOS) termed the Lexical Stress Ratio (LSR) and the Coefficient of Variation Ratio (CVR). The LSR is a weighted composite of amplitude...

Previous studies, conducted in different countries (e.g. Australia, Canada, India, Republic of Ireland, USA, UK), have shown that speech-language pathologists (SLPs) use nonspeech oral motor exercises (NSOMEs) to treat speech sound disorders (SSDs), bringing attention the substantial debate regarding clinical effectiveness NSOMEs. The aim present study was investigate and characterize NSOMEs by...

We studied a group of immigrants who were following regular, teacher-fronted Dutch classes, and who were assigned to three groups using either a) DutchCAPT, a Computer Assisted Pronunciation Training (CAPT) system with Automatic Speech Recognition (ASR) that provides feedback on a number of Dutch speech sounds that are problematic for L2 learners, b) a CAPT system without feedback, c) no CAPT s...

A technique, first introduced in the context of pseudoperiodic sound waves, is here applied to the problem of detecting the phase of phase coherent and also phase noncoherent chaotic oscillators. The approach is based on finding sinusoidal fits to segments of the signal, therefore obtaining, for each segment, an appropriate frequency from which a phase can be derived. Central to the method is a...

compounds on Earth. No known form of life can survive without it, and for a human, a day without water is a day of suffering. Water is such a familiar element in everyday life that one might assume that it is completely understood. Unfortunately, that is not true. Our ignorance is well illustrated by sonoluminescence, the astounding ability of water to concentrate energy from sound waves into f...
