Research on Vowel Formant Frequencies and Voice Perturbation Parameters in Pathological Voices after Larynx Cancer. (Trabajo Fin de Grado Inédito). Universidad de Sevilla, Sevilla.https://hdl.handle.net/11441/171797The present study aims at analyzing the influence that larynx cancer has had in the voice parameters and formant frequency in English and Spanish vowels through the acoustic analysis of sustained vowels and a list of words. Two syllable words were considered for the Spanish task (CVCV) and words with different syllabic patterns were used for the English part. Besides, vowels /a/ and /e/ were taken into account for voice parameters. Three participants have been selected: two men and one woman. The activity they were given consisted of pronouncing different words with all the English and Spanish vowels to check their irregular voice after that their illness left them. Moreover, they were asked to pronounce long /a/ and /e/ to check their voice parameters. The results of the study seem to suggest that both English and Spanish vowels have uncommon formant frequencies and voice parameters irregular results. This is due to the fact that all of them have suffered larynx cancer and have different consequences: one of them does not have larynx, the other one has only one vocal fold and the last one have both vocal folds, but only one of them works correctly.application/pdf38 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
