Final answer:
Dysphonia refers to difficulties with speech specifically relating to the voice, including problems such as a hoarse or raspy voice. It is separate from dyslexia, which can affect reading, writing, and speaking due to language comprehension issues, though both can impact the way a person communicates.
Step-by-step explanation:
The term Dysphonia actually means difficult or faulty speech. It is a condition where individuals have issues with their voice, such as the volume, pitch, tone, or quality of the sound they produce when they speak.
Compared to dyslexia, which is related to difficulties with language that can affect reading, writing, speaking, and occasionally numerical understanding, dysphonia specifically refers to problems with a person's vocal sounds. For example, someone suffering from dysphonia may have a hoarse or raspy voice.
Healthy human speech production involves the functioning of vocal cords, adjustment of the throat and mouth cavity, and the utilization of the tongue to modulate fundamental frequencies. These physical elements combined with adequate breath support generate the sounds necessary for clear speech. Any problems with these components, caused by various factors such as strain or illness, can lead to dysphonia.
