Document Summary
Speech, language, communication, hearing: speech (vocal and verbal) Symbolic voluntary neuromuscular process that carries meaning. Non-symbolic neuromuscular process without discernable meaning (jargon, babble ) Four overlapping processes work systematically to produce speech: respiration, phonation, resonation, articulation. Verbal = language system: respiration - power source of speech. Lungs are in state of (-) pressure. Lungs are in state of (+) pressure. Respiratory rest: phonation rapid opening and closing of the glottis. Regulates air flow to produce voiced and voiceless segments. Voiced phonation is created sub-glottal air pressure. The folds are blown apart due to: inherent elasticity of the folds, velocity of air rushing through. The number of cycles/second determines a person"s fundamental frequency or the average pitch of their voice. Men about 100 hz 150 hz (125 hz) Women about 200 hz 220 hz. Children could be all the way up to the 300 hz: resonance.
