language disability

a. Communication: The exchange of ideas, information, or concepts. It can be non-language and can be communicated through body language and facial expressions. The prerequisites for communication are an exporter, a message, and a receiver. As long as the sender can correctly and completely convey his message and the receiver can fully understand the message, the meaning and purpose of communication can be counted. b. Language: It is a set of established symbols or words produced in systematic spoken language and used as a tool for humans to express and receive messages. c. Speaking: Expressing language in a vocal or verbal way, as a means of communication between people is called speaking. The production of speech involves the following four processes: (a) Respiration produces the energy of pronunciation. (B) Vocalization is the production of sound through the vibration of the vocal cords. (C) Resonance is the uniqueness of the sound to identify the speaker. (D) The clear voice is the phoneme created by the movement of the mouth and tongue. Damage to any of these processes will lead to language abnormalities, but may not interfere with language learning or reading or writing. Hearing loss can also cause speech abnormalities. If a child cannot hear his voice, it is difficult for him to speak. Communication anomalies refer to abnormalities in both speech and language. Speaking abnormalities refer to abnormal speech intelligibility or fluency. Linguistic abnormalities refer to the difficulty in understanding the language symbol system, that is, the development of listening, speaking, reading and writing abilities. d. Cromer's definition of language abnormality is: it is not caused by other disorders (such as hearing impairment, mental retardation, personality disorder).
