“…It is well known that patients with vocal alterations frequently present worse scores in the protocols of vocal self-assessment (17,20) ,an expected result in laryngeal tumors, not always investigated in cases of tumors of head and neck, except larynx. Additionally, subtle changes in vocal quality, or even the well-known wet voice (6,7,10) , may appear as early signs that indicate some altered laryngeal function, which in the conditions of these patients, may or may not present with dysphagia.…”

“…However, throughout the collection it was observed that the patients had vocal complaints after the treatment of head and neck cancer, regardless of whether they were laryngeal or thyroid tumors, in which there is a proven vocal alteration associated with the treatment, whether surgery, chemotherapy and/or radiotherapy, the latter causing histological changes in the composition of the vocal folds, such as fibrosis and reduction of muscle mass (12,13,22,23,28) . Thus, analyzing vocal data of the dysphagic patient can bring important and aggregating contributions to the speech-language pathology Vocal signs and symptoms and dysphagia in HNC (SLP) evaluation, even more so as to not use invasive methods for vocal evaluation (2,3,6,7,10) . Hence, the analysis of vocal data can be used in screening, even for the eligibility of urgency in large populations or services.…”

“…Penetration and aspiration can cause several vocal quality changes (9) . Evaluating the voice of the dysphagic individual can bring enriching data, especially in the case of screening, since it is a quick, simple and non-invasive method of evaluation that can be performed with the contribution of computerized acoustic analysis (10) .…”

RESUMO Objetivos Avaliar a presença de sinais e sintomas vocais e função vocal em indivíduos com disfagia, tratados de câncer de cabeça e pescoço – CCP e identificar os valores de corte dos respectivos instrumentos. Métodos Estudo prospectivo com 96 indivíduos (68 homens e 28 mulheres), divididos em grupo experimental – GE (pacientes tratados de CCP com disfagia, independente de queixa vocal) e grupo controle – GC (sem queixas autorrelatadas de voz e deglutição, pareados em média de idade e sexo com GE), que responderam a um questionário com dados de identificação e caracterização da amostra, Lista de Sinais e Sintomas Vocais – LSS, e dois protocolos de avaliação vocal (Índice de Função Glótica – IFG e Escala de Sintomas Vocais – ESV). Por fim, as notas de corte dos protocolos foram identificadas por meio da curva ROC (Receiver Operating Characteristic). Resultados Indivíduos do GE apresentaram mais sinais e sintomas vocais e maiores escores no IFG e ESV que os indivíduos do GC, além de pior autoavaliação vocal. Os três instrumentos apresentaram máxima área sob a curva ROC, com valores de corte ESV=17, IFG=4 e LSS=6 pontos. Conclusão Indivíduos tratados de CCP com disfagia apresentam mais sinais e sintomas vocais, pior autopercepção da disfunção vocal e maior prejuízo nos aspectos de limitação, emocional e físico da voz, que indivíduos vocalmente saudáveis. Os três instrumentos evidenciaram sensibilidade e especificidade máximas, podendo ser utilizados como ferramentas de triagem.

Dysphagia is a symptom of many neurological disorders. Existing diagnosis systems are either invasive or require swallowing liquids, which are costly and harmful to humans. In this work, we design a smart dysphagia detection system based on speech signals. Rather than the voice data acquired by traditional microphones, we apply a bone conduction headset for vibration signal acquisition from the throat to get cleaner speech signals.After speech feature extraction, under-sampling is performed to deal with the imbalanced data problem, and principal component analysis is used for dimensionality reduction. In this paper, we construct an ensemble adaptive boosting classifier to detect the dysphagia patient. Experimental results show that the testing classification accuracy of the proposed system reaches 71.2%. Sensitivity and specificity can reach 66.6 % and 76 %, respectively.

This study investigated the acoustic and perceptual outcomes of a specific six-week voice training protocol for transgender women, by analyzing acoustic features of speech and voice. The authors sought to establish statistical and clinical significance between speaking fundamental frequency and self-perceptual ratings of communicative experiences, pre-and post-training. Methods: Speech samples were collected from 10 transgender women. Acoustic variables analyzed for this research include: fundamental frequency (F0) of vowel prolongation, speaking fundamental frequency (SFF) of spontaneous speech, formants (F1 and F2), pitch perturbation quotient (PPQ), relative average perturbation (RAP), noise-to-harmonic ratio (NHR), and intensity. Participants also completed a selfevaluation of communicative experiences using a five-point scale from the Transsexual Voice Questionnaire, Male-to-Female (TVQMtF). Speech samples were collected pre-and post-training to establish statistical and clinical significance. Results: Statistically and clinically significant gains were found between pre-and post-training in the areas of F0 in vowel prolongation, and SFF during spontaneous speech. There were generally medium effect sizes for F1 and F2, PPQ, RAP, NHR, and intensity. These analyses were limited by sample size. Results suggest that F0 of vowel prolongation, SFF, SFF variation, formant modification, and intensity are suitable targets for evidence-based practices for transgender women. iii ACKNOWLEDGMENTS I would like to thank everyone who provided support and guidance to complete this thesis. All mistakes are mine alone. I would first like to thank my advisor and academic supervisor Dr. Leslie Mahler. Her patience, thoughtfulness, and confidence in my abilities helped me to persevere throughout this process. Thank you to Kimberly Dahl, your hard work has provided an opportunity for which I will be eternally grateful. Thank you to Madison Turner, for all of her hard work and patience, I hope this experience was of value. Thanks are due to my thesis committee, from whom I have learned to better myself personally and professionally.
