What type of sensory information is crucial during the motor speech production process?

Understanding the motor speech production process involves recognizing that both internal and external sensory information play significant roles. Internal sensory information consists of proprioceptive feedback from the muscles involved in speech production, allowing individuals to monitor their own movements and make necessary adjustments for accurate articulation and fluency. This internal feedback helps speakers understand the position and movement of their articulators, such as the tongue, lips, and soft palate.

On the other hand, external sensory information includes auditory input, which allows speakers to hear their own voice and the speech of others. This auditory feedback is crucial for monitoring pitch, loudness, and clarity, facilitating adjustments in speech production during communication. Visual information, which can include observing the movements of one's own articulators in a mirror or watching others speak, also contributes to effective speech production, enhancing coordination and timing.

Therefore, integrating both internal and external sensory modalities is essential for producing clear and effective speech, making the option that encompasses both types of information the most accurate.
