Deaf patients can be categorized into prelingual deafness and postlingual deafness. Prelingual deafness patients do not speak, while some postlingual deafness patients will retain the ability to speak.
1. Pre-speech deafness: If severe or profound deafness occurs at birth or shortly after birth, and the external sound signals cannot be accepted, the ability to learn speech is lost. If this type of deafness is not medically intervened as early as possible, it will miss the optimal period of hearing and speech development, resulting in the inability to form the function of speech, which can only produce simple sounds, but cannot be expressed accurately into sentences.
2. Post-speaking deafness: Some patients’ deafness occurs after speech acquisition, but because of the severity of deafness, long-term inability to hear and monitor their own vocalizations, speech clarity gradually decreased, pitch disorders, speech function gradually degraded, such a type of patients with a shorter duration of the primary disease, may be in the short-term remnants of the performance of the speech, but will eventually gradually lose the ability to speak.
If you want to know whether a patient with total hearing loss has the ability to speak, you need to actively seek medical treatment and complete the relevant examinations before being judged by a specialist.
