“…Dentre os poucos estudos encontrados na literatura, grande parte é relativamente atual, publicado após o ano 2000 [19][20][21][22][23][24] . Em alguns trabalhos a investigação da qualidade vocal foi baseada em dados de anamnese e avaliações perceptivo-auditivas 19,21,22,24 enquanto que em outros, a mesma foi baseada em análises espectrográficas 20,23 . De forma geral, o objeto de pesquisa dos autores citados anteriormente não foi a "respiração oral/nasal" propriamente dita, e sim situações análogas promovidas por alergias respiratórias 19,22,24 , obstrução nasal 23 e patologias como hipertrofia de tonsilas palatinas 20 .…”

RESUMOObjetivo: investigar parâmetros espectrais (f 0 e formantes) descritivos da voz de crianças respiradoras orais, visando contribuir na caracterização desta população e, consequentemente, na efetividade do diagnóstico. Métodos: foram selecionadas 50 crianças respiradoras orais e 101 crianças com respiração nasal de ambos os gêneros entre cinco e dez anos. Os sinais de fala foram obtidos a partir das gravações de sentenças-veículo e os segmentos das vogais orais [a], [i] e [u] do português falado no Brasil em posição tônica foram selecionados para a estimação da frequência fundamental (f 0 ) e da frequência dos três primeiros formantes (F 1 , F 2 e F 3 ). O software Praat foi utilizado para gravar, recortar e processar os sinais. Resultados: a frequência fundamental das vogais [i] e [u] apresentouse menor nos respiradores orais, enquanto que a frequência de F 1 da vogal [u] foi mais elevada no mesmo grupo. Conclusão: a partir dos resultados expostos, concluiu-se que a frequência fundamental consiste em um parâmetro vocal que auxilia na diferenciação de crianças respiradores orais e respiradoras nasais, contribuindo, desta forma para uma caracterização mais efetiva do respirador oral.

“…However, it tended to increase for some patients 4 weeks after the operation, suggesting replacement of a soft tissue with the tonsils 13 . In this study, the HNR values were decreased generally.…”

“…Comparison between objective and subjective findings Changes in the structure of the vocal tract after an operation are assumed to cause changes in the speech characteristics of the individuals 13 . Examination of the time-course changes after tonsillectomy revealed that acoustic parameters were noted to not cause significant differences on the study samples.…”

Introduction: Tonsillectomy is a common surgical procedure performed in otolaryngology setting worldwide. It is a procedure to remove the palatine tonsils, which are one of the major structures in the oropharynx which constitute part of the vocal tract. The study aimed to determine acoustic changes in post-tonsillectomy patients. Methodology: Voice sampling was collected using Praat software before and after operation, which was one day before operation and within 2-3 weeks after the operation respectively. Acoustic parameters including fundamental frequency, jitter, shimmer, harmonic to noise ratio and first formant frequency were analyzed by using paired t-test. Results: A total of 27 participants that underwent tonsillectomy or adenotonsillectomy were involved in this study. The age range of participants was 3-56 years old. The mean age of study was 18.57. There was no significant difference for all the acoustic parameters between pretonsillectomy and post tonsillectomy. However, there were noticeable voice changes through auditory as perceived by participants or caregiver. Conclusion: Although patient and care givers do notice a significant voice changes, but objectively this finding is not reveals during objective voice assessment.

“…Ilk, Erogul. (10) and his colleagues reported the changes were minimal and have little effects on acoustic parameters except for the professional speakers and singers. Therefore, the changes in voice quality were considered to be negligible, although it seemed to be a problem that cannot be disregarded.…”

Removal of lymphoid tissue mass (Tonsils) from the vocal tracts between the vocal folds and lips may cause a change in voice quality postoperatively. This study was conducted to determine the effect of tonsillectomy on voice in terms of its quality under the Category: Hoarse, Harsh and Breathy. This study was done on 50 patients (32 females and I8 males) who underwent tonsillectomy for chronic tonsillitis during a period from January 2004 to February 2005 in a Tertiary Care Centre. The preoperative and postoperative voice samples of vowels /a/, /i/ and /u/ were recorded in a computer. The recordings were analyzed using a computerised programme, Dr Speech Software Version 4 (Tiger DRS, Inc. Seattle, USA). The patients reported that they did not perceive any change in his/her voice after surgery. The vocal assessment between the preoperative, first postoperative followup and second postoperative follow-up for all the three vowels /a/,/i/ and /u/ were not statistically significant. As a conclusion, tonsillectomy do not appear to change the acoustic features of vowels remarkably, but in professional voice users they should be warned for any possible changes in voice after surgery.
