DIFFERENCES BETWEEN VOCAL PARAMETERS OF COCHLEAR IMPLANTED CHILDREN AND CHILDREN WHO USE INDIVIDUAL SOUND AMPLIFICATION DEVICE Diferenças entre parâmetros vocais em crianças usuárias de implante coclear e em crianças usuárias de aparelho de amplificação sonora individual

Conflict of interest: non-existent requires of the motor information of the pathways for articulation and sensory information. Sensory information is obtained through auditory feedback, which also interferes with the correction and improvement of muscle control of the organs involved in vocal production3. Due to the lack of kinesthetic feedback presented by these children, the vowels tend to be produced with a lower distinction. This lack of distinction is acoustically revealed, among other things, increasing the frequency of the first formant (F1) and a decrease in the frequency of the second formant (F2)4. There are compromised characteristics in relation to vocal aspects found in children with deficits in hearing. Resonance can present nasality because the language generally presents posteriorized due to laryngeal tension, affecting the quality „ INTRODUCTION
