“…A variety of studies in children and adults show that vocal pathology and/or dysphonia are associated with increased jitter and shimmer [1,5,[12][13][14][15][16]. Also, the onset of mutation in children was accompanied by increased acoustic voice perturbation [17].…”

“…It has been suggested, that jitter and shimmer may even indicate subtle changes in the vibratory properties of the vocal folds [16,18,19]. Based on this jitter and shimmer have been characterized as informative and clinically valuable parameters to determine pathology and mutation onset in childrens' voices [1,13].…”

“…Many term-born, otherwise healthy children develop mild dysphonia as the result of overuse of the voice, e.g., sustained use of the voice, voice use at loud volumes. Such behaviour may be amenable to voice therapy [28][29][30][31]. It is currently unclear whether voice therapy would have any effect on the voice quality of children whose vocal hyperfunction is secondary to underlying structural pathology, such as the very preterm participants in this study.…”

“…In six cases, supraglottic tightening was such that mucosal wave was unable to be assessed due to obscuration of the vocal folds during phonation. Vocal hyperfunction is common in childhood [28]. Many term-born, otherwise healthy children develop mild dysphonia as the result of overuse of the voice, e.g., sustained use of the voice, voice use at loud volumes.…”

“…At first, the only strategy used by professionals in the field was limited to clinical, auditory-perceptual, and physiological evaluations, which according to MARTINS, , and VALADEZ et al (2012), are invasive character techniques and often cause nuisance and malaise on the patient. However, technological advances have enabled the emergence of computational mechanisms allied to procedures, and, therefore, non-invasive, i.e.…”

Oral communication comprises one of the most important forms of social interaction. The process of learning the spoken language depends on the hearing, therefore, the total or partial loss of hearing sensitivity hinders such aspect. Digital signal processing techniques with non-invasive character are used for diagnosis, support and improvement of the voice quality of the deaf. Thus, the present study aims to propose and develop a system of analysis and correction of vocal disorders by means of visual and tactile feedback with module implemented in programmable device type FPGA (Field Programmable Gate Array). The results point to the potential of a proposed intervention as a helper for sensory substitution, being based on the monitoring and control of speech, in order to allow for the assessment and remediation by means of an electronic resource, allowing deaf individuals to obtain a support for learning the spoken language. The possibilities for improvements in communication skills observed in this study are dependent on the capability of the device together with the speech therapist, integrating therapies with the support of the family, the time and the motivation of the user, factors that cooperate for the success of this approach. KEYWORDS:Deafness, Speech, FPGA, Assistive Technology and Visual-Tactile Stimulation. SISTEMA VÍSUO-TÁTIL SINTETIZÁVEL E PROTOTIPÁVEL EM FPGA: UMA ALTERNATIVA PARA ANÁLISE E MELHORIA DA QUALIDADE DA VOZ DE DEFICIENTES AUDITIVOSA comunicação oral compreende uma das mais importantes formas de interação social. O processo de aprendizado da linguagem falada depende da audição, logo, a perda total ou parcial da sensibilidade auditiva dificulta tal aspecto. Técnicas de Processamento Digital de Sinais com caráter não-invasivo são usadas para diagnóstico, apoio e melhoria da qualidade da voz dos surdos. Desse modo, o presente estudo tem como objetivo propor e desenvolver um sistema de análise e correção de desordens vocais por meio da realimentação visual e tátil com módulo implementado em um dispositivo programável do tipo FPGA (Field Programmable Gate Array). Os resultados apontam para o potencial de uma proposta de intervenção como medida auxiliar para substituição sensorial, sendo baseada no monitoramento e controle da fala, de modo a permitir a avaliação e remediação por meio de um recurso eletrônico, possibilitando que os indivíduos surdos obtenham um suporte a mais para aprendizado da língua oral. As possibilidades de melhorias nas habilidades comunicativas observadas neste estudo dependem da potencialidade do dispositivo em conjunto com a atuação do fonoaudiólogo, a integração das terapias com o apoio da família, o tempo de utilização e a motivação do usuário, fatores estes que colaboram para o sucesso desta abordagem.
