[VOT analysis in cleft palate patients after surgery].
To determine the factors that modify the measures 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 abnormal intraoral pression. This doesn't allow the normal generation of voiceless 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 associated with increased VOT. Our results are based in a correct sample and statistical analysis by multiple lineal regression.
