Estudio del VOT en pacientes intervenidos de fisura palatina

Objectives. To determine the factors that modify the mea- sures of voice onset time (VOT) as acoustic parameter in operated cleft palate children. The voice of cleft palate patient is defined by the generation of an abnor- mal intraoral pression. This doesn't allow the normal generation of voi- celess plosives consonants and produces an increased VOT. Acoustic analysis of voice quantifies these parameters. In this study we observed an increased VOT if the patient hadn't got a normal teeth occlusion and a normal soft palate function. Also VOT measures were influenced by cleft lip and delay in beginning of ortodoncy. Hearing loss is asso- ciated with increased VOT. Our results are based in a correct sample and statistical analysis by multiple lineal regression.
