Sound retention of speech sound by artificial cochlea.

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, ...

Artificial Intelligence in Organised Sound

Molecular mechanisms of sound amplification in the mammalian cochlea.

Mammalian hearing depends on the enhanced mechanical properties of the basilar membrane within the cochlear duct. The enhancement arises through the action of outer hair cells that act like force generators within the organ of Corti. Simple considerations show that underlying mechanism of somatic motility depends on local area changes within the lateral membrane of the cell. The molecular basis...

Sound change and speech evolution

Strictly phonemic models of the lexicon hold that the pronunciation of a phoneme is determined solely by the grammar, not word identity, and therefore predict that sound change should occur in lockstep across the lexicon. Early work on lexical diffusion in the 60’s and 70’s called the phonemic model into question by suggesting that sound change can proceed at different rates in different words,...

Assessing toddlers' speech-sound discrimination.

OBJECTIVE Valid and reliable methods for assessing speech perception in toddlers are lacking in the field, leading to conspicuous gaps in understanding how speech perception develops and limited clinical tools for assessing sensory aid benefit in toddlers. The objective of this investigation was to evaluate speech-sound discrimination in toddlers using modifications to the Change/No-Change proc...
