PURPOSE To identify in the literature, normative data about the perceptual auditory and acoustic characteristics of the voice of hearing-impaired cochlear implant adult users. SEARCH STRATEGY A systematic search was carried out in the Virtual Health Library, Web of Science, Science Direct, SciELO, and SCOPUS databases with no temporal restriction. SELECTION CRITERIA The articles were selected if they led with citation to normative data of the acoustic analysis of the voice of deaf cochlear implant users. And duplicate articles, case studies, letters to the editor, reviews, and studies that were not directly related to the topic were excluded. DATA EXTRACTION The data from each article were extracted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis ch...

METHODS A seven-day protocol with Finnish tube was performed with guidance for its home replication twice a day. A 46-years-old man with profound bilateral sensorineural hearing loss, musician and composer participated. Before and after the application of the protocol had undergone tonal audiometry, nasofibrolaryngoscopy, acoustic analysis with Praat and auditory-perceptual evaluation of the voice with Voice Profile Analysis Scheme for Brazilian Portuguese. RESULTS The postintervention auditory-perceptual analysis identified reduction of the deviation in lip spreading, extensive labial range, raised tongue body, pharyngeal expansion, nasal resonance, larynx height, larynx and vocal tract tension and irregularity, pitch, speech rate, and a better respiratory support. The maximum phonation time reduced, probably because of e...

Methods: twenty-seven adults of both genders, with cochlear implants, in the age range of 19 to 57 years participated. The participants answered the self-assessment protocols Voice Handicap Index and Voice Symptom Scale. Furthermore, the participants answered an additional question about how they rated their voices. Results: for the Voice Handicap Index, the average score was 28.74, in total, and the average score for the Voice Symptom Scale was 29.22, in total. The correlation between the scores of the Voice Handicap Index and the self-perception of the voice showed that the worse the perception, the more handicap in every domain of the protocol. For the Voice Symptoms Scale, the results showed that there is a positive and moderate correlation between the self-perception of the voice and the total scores as well as for the impairment and emotional subscales. Conclusion: this study verified the presence of handicap and symptoms related to voice, mainly, regarding physical, functional and limitation aspects for the adults with cochlear implants. There is a positive and moderate correlation between the score of the protocols applied and self-evaluation of the vocal quality of the participants.

This is a cross-sectional, prospective study. One hundred and fifty voice samples, consisting of 50 sustained vowels, 50 samples of connected speech, and 50 samples of conversational speech, belonging to 25 adults with hearing impairment with cochlear implants and 25 adults with normal hearing, were perceptually analyzed for inter-rater agreement and intra-rater reliability. Three experienced judges rated the voice samples using visual analog scales of parameters considered relevant for cochlear-implanted population such as articulation, intonation, and resonance. The raters participated in three training sessions for calibration and had 1 month to complete the ratings individually. Twenty percent of the samples were repeated randomly to verify intra-rater reliability. The lev...

Hearing loss can impair voce production, causing social, educational, and speech limitations, with specific deviation of the communication related to speech and voice. Usually, the voice is not the main focus of the speech-language pathology therapy with individuals with hearing loss, but its deviations can represent such a negative impact on this population that it can interfere on speech intelligibility and crucially compromise the social integration of the individual. The literature vastly explores acoustic and perceptual characteristics of children and adults with hearing loss. Voice problems in individuals with this impairment are directly related to its type and severity, age, gender, and type of hearing device used. While individuals with mild and moderate hearing loss can only present problems with resonance, severely impaired individuals may lack intensity and frequency control, among other alterations. The commonly found vocal deviations include strain, breathiness, roughness, monotone, absence of rhythm, unpleasant quality, hoarseness, vocal fatigue, high pitch, reduced volume, loudness with excessive variation, unbalanced resonance, altered breathing pattern, brusque vocal attack, and imprecise articulation. These characteristics are justified by the incapability of the deaf to control their vocal performance due to the lack of auditory monitoring of their own voice, caused by the hearing loss. Hence, the development of an intelligible speech with a good quality of voice on the hearing impaired is a challenge, despite the sophisticated technological advances of hearing aids, cochlear implants and other implantable devices. The purpose of this chapter is therefore to present an extensive review of the literature and describe our experience regarding the evaluation, diagnosis, and treatment of voice disorders in individuals with hearing loss.
