Intonation and voice

Intonation and voice are human language expression forms, which are dominated by the language center. When the cerebral hemisphere is damaged (stroke), aphasia can occur. Intonation refers to the pronunciation and tone in the language process, and the vocal organs and their innervated neuropathy can cause abnormal intonation. Voice abnormality refers to disordered language rhythms, poor expression, and uneven speed. It is found in tremor paralysis, chorea, hepatolenticular degeneration, and stuttering. Dysphonia is dysphonia and articulation, but the understanding of language is normal. It is found in myopathy, bulbar paralysis, cerebellar disease, tremor paralysis and so on.
