“…From this finding it can be inferred that the measures that followed normal distribution are likely to be used as reference values for the interpretation of the results from female acoustic voice analyses, with or without laryngeal disorders. In addition, the study showed that all measures with or without normal distribution had similar results of those reported in national and international literature 4 . In the same line, a study 25 was conducted to verify the normal vocal acoustic characteristics of Arabs.…”

“…These structures are also fundamental for the expiration and maintenance of the abdominal breathing support for voice production, mainly in its aspects of support MPT and SP (1) . The development of respiratory control is important for the maintaining air pressure, during phonation (13) . The abdominal respiratory support provides a significant improvement in vocal extension rates (3) loudness (subjective sensation of SP) e pitch (subjective sensation of frequency) (14) .…”
