Assessment of Speech Sound Production by Story-retelling in Persian Speaking Children: Introducing a New Instrument

Background: Speech and language pathologists should include connected speech assessment as part of their evaluation for children with speech sound disorders. The purpose of the present study was to design and validate an instrument for assessment of articulation by story-retelling for Persian children.Methods: 261 typically developing children, aged 4-5 years old in Iran, Tehran, in 2016-2017, ...

Anatomical correlates of foreign speech sound production.

Previous work has shown a relationship between brain anatomy and how quickly adults learn to perceive foreign speech sounds. Faster learners have greater asymmetry (left>right) in parietal lobe white matter (WM) volumes and larger WM volumes of left Heschl's gyrus than slower learners. Here, we tested native French speakers who were previously scanned using high-resolution anatomical magnetic r...

Single Word Quick Repetition Test for Speech Sound Production in Farsi Speaking Children: Development, Reliability and Validity

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...

Sound Production Treatment: Application with severe apraxia of speech

Speech sound acquisition, coarticulation, and rate effects in a neural network model of speech production.

This article describes a neural network model of speech motor skill acquisition and speech production that explains a wide range of data on variability, motor equivalence, coarticulation, and rate effects. Model parameters are learned during a babbling phase. To explain how infants learn language-specific variability limits, speech sound targets take the form of convex regions, rather than poin...
