Abstract
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.
Highlights
The hearing plays an essential role in human communicative process, considering that the integrity of such sense gives to the individual the ability to hear, understand and play properly sounds from the environment in which one lives, as well as being a perception mechanism of the world
A necessary and accurate communicative function requires the performance of mechanisms linked to speech, but the hearing loss, from the lightest to the most severe level, inhibits the development of language and speech, and entail losses of various proportions, such as educational and psychosocial, impacting negatively on the affective and social relations of the hearing impaired person (SPERI, 2013), facts like these strengthen the proposition that the effects related to lack of auditory stimulation on the development of oral language and speech intelligibility are harmful (OLIVEIRA, PENNA and LEMOS, 2015)
Many significant changes can be found in the history of deaf education, focusing mainly on the speech and auditory-verbal approaches, which according to BEVILACQUA et al (2011) and LUCCHESI et al (2015), aim to assist individuals with hearing loss to use their residual hearing to learn listening and speaking, i.e. methods that advocate the education for the deaf must be based on oral communication
Summary
The hearing plays an essential role in human communicative process, considering that the integrity of such sense gives to the individual the ability to hear, understand and play properly sounds from the environment in which one lives, as well as being a perception mechanism of the world. In this context, the communicative function is compromised by total or partial loss of hearing sensitivity, inserting the deaf individuals in a context marked by socio-educational, emotional consequences and related to cognition, for this reason this theme contains a social call, requiring methodologies and mediator resources for the betterment of the perceptual processes, language acquisition through the sensory substitution and in social interactions (ALVES, SOARES & OLIVEIRA, 2014). Many significant changes can be found in the history of deaf education, focusing mainly on the speech and auditory-verbal approaches, which according to BEVILACQUA et al (2011) and LUCCHESI et al (2015), aim to assist individuals with hearing loss to use their residual hearing to learn listening and speaking, i.e. methods that advocate the education for the deaf must be based on oral communication
