BACKGROUND Detailed knowledge of the neurophysiology of speech acquisition is important for understanding the developmental aspects of speech perception and production and for understanding developmental disorders of speech perception and production. METHOD A computer implemented neural model of sensorimotor control of speech production was developed. The model is capable of demonstrating the...

Speech impairment is a frequent and often serious symptom of Parkinson's disease (PD), characterized by a disorder of phonation, articulation and prosody. While research on the pathogenesis of the prominent limb motor symptoms has made considerable progress in recent years, the pathophysiology of PD speech impairment is still incompletely understood. To investigate the neural correlates of spee...

Understanding the neural mechanisms underlying speech production has a number of potential practical applications. Speech production involves multiple feedback loops. An audio-vocal monitoring system plays an important role in speech production, based on auditory feedback about the speaker's own voice. Here we investigated the mu-rhythm activity associated with speech production by examining ev...

The occurrence of voice disorder and of non-modal phonation were measured in the speech of 53 children. Thirty seven monolingual English speaking children with developmental speech disorder and compared with that in 16 age-matched children with normal speech development. The children’s ages ranged from 4 to 6 years. The speech disordered children were further assigned to 3 subgroups according t...

One of the interesting topics on multimedia domain is concerned with empowering computer in order to speech production. Speech synthesis is granting human abilities to the computer for speech production. Data-based approach and process-based approach are the two main approaches on speech synthesis. Each approach has its varied challenges. Unit-selection speech synthesis and statistical parametr...

Oronasal region, as an important organ of taste and smell, being respected for its impact on the resonace, which is crucial for any normal speech production. Different congenital, acquired and/or developmentalpdefect, may not only have impacts on the quality of respiration, phonation, resonance, also on the process of a normal speech. This article will enable readers to have more focus in such ...
