8. Perception and production of speech in a hearing impaired child during therapy / Percepção e produção de sons de fala em uma criança com deficiência auditiva em terapia fonoaudiológica
Introduction: Very few studies discuss speech development in hearing impaired children in the first years of life due to methodological difficulties and the number of variables involved. Acoustic inspection of articulatory adjustments and attempts to imitate a model made by the infant in different contexts can be a method to comprehend the manner in which fi

11. A percepção de plosivas alveolares na produção de um sujeito com deficiência auditiva: um estudo fonético acústico / The perception of alveolar plosives produced by a hearing-impaired subject: an acoustic phonetic study
Hearing impairment affects speech production and perception. One of the difficulties the hearing-impaired faces is producing/perceiving the contrast between voiced and voiceless sounds, mainly those which are characterized by a total obstruction between articulators such is the case of plosives, which happen to be one of the highest frequency sounds in Portu
