What Is a Motor Speech Disorder?  

Back

impairment of speech production caused by
defects of the neuromuscular system, the motor
control system, or both

Front

Systems of Speech Production  

Back

-Respiratory
■ Phonatory
■ Resonatory
■ Articulatory

Front

Respiratory System

Back

■ It regulates the inhalation-exhalation
cycle for passive breathing and for
producing speech.

Front

Phonatory System

Back

■ The phonatory system regulates the
production of voice and the prosodic,
or intonational, aspects of speech

Front

Resonatory System

Back

■ The resonatory system regulates the
resonation or vibration of the airflow as
it moves from the pharynx into the oral
or nasal cavities.

Front

Articulatory System

Back

■ Regulates the control of the articulators
within the oral cavities to manipulate
the outgoing airflow in different ways,
usually at very high speeds.

Front

Speech Motor Control

Back

■ To maintain speed and fluency when
speaking, and to maintain accuracy of
movements, the sequences of movements
are programmed together as a single unit

Front

Motor Planning

Back

■ Refers to the process that defines and sequence articulatory
goals prior to their occurrence.

Front

■ Motor Programming

Back

■ Refers to the process responsible for establishing and
preparing the flow of motor information across muscles for
speech production and specifying the timing and force
required for the movements.

Front

■ Motor Execution

Back

■ Refers to the processes responsible for activating relevant
muscles during the movements used in speech production.
