Speech production is the process by which thoughts are translated into speech. This includes the selection of words , the organization of relevant grammatical forms, and then the articulation of the resulting sounds by the motor system using the vocal apparatus .
Principles of motor learning theory and intense speech-motor practice seem to be the most effective; Non-speech oral motor therapy is not necessary or sufficient; A multi-sensory approach to therapy may be beneficial: [25] using sign language, pictures, tactile cues, visual prompts, and augmentative and alternative communication (AAC) can be ...
The production of speech is a highly complex motor task that involves approximately 100 orofacial, laryngeal, pharyngeal, and respiratory muscles. [2] [3] Precise and expeditious timing of these muscles is essential for the production of temporally complex speech sounds, which are characterized by transitions as short as 10 ms between frequency bands [4] and an average speaking rate of ...
Motor speech disorders are a class of speech disorders that disturb the body's natural ability to speak due to neurologic impairments. These neurologic impairments make it difficult for individuals with motor speech disorders to plan, program, control, coordinate, and execute speech productions. [ 1 ]
Apraxia of speech (AOS) is a neurogenic communication disorder affecting the motor programming system for speech production. [6] [7] Individuals with AOS demonstrate difficulty in speech production, specifically with sequencing and forming sounds. The Levelt model describes the speech production process in the following three consecutive stages ...
Neurocomputational models of speech processing are complex. They comprise at least a cognitive part, a motor part and a sensory part. [2]The cognitive or linguistic part of a neurocomputational model of speech processing comprises the neural activation or generation of a phonemic representation on the side of speech production (e.g. neurocomputational and extended version of the Levelt model ...

In both humans and non-human primates, the auditory dorsal stream is responsible for sound localization, and is accordingly known as the auditory 'where' pathway. In humans, this pathway (especially in the left hemisphere) is also responsible for speech production, speech repetition, lip-reading, and phonological working memory and long-term ...
