“…These characteristics include abnormal variations in speech rate, 2,3 increased voice intensity, 4 variability in fundamental frequency (F 0 ), 2,3,5,6 abnormal intonation contours, 3,6 inaccurate production of vowels, 2,7-9 excessive nasality and/or resonance irregularities, 10-12 irregular tongue positioning, 2,13-15 and inadequate laryngeal function. [15][16][17][18] Research has shown that after prolonged hearing loss, postlingually deaf adults can develop voice and speech abnormalities similar to prelingually deaf adults including deviations in intonation, 19 pitch/F 0 , 19,20 speech rate [19][20][21] and vowel duration, 19,20 nasality, 19 articulation, 19,20 voice intensity, 19,22 and tongue positioning. 23 However, postlingually deaf adults have been shown to effectively regain speech discrimination, voice quality, and speech production capabilities following implantation.…”

“…Several studies have shown that speakers born deaf or deafened before learning English "blur" the distinction between voiced and voiceless consonants; they fail to implement this phonemic contrast with sufficienlly differentiated VOT (Monsen, 1976), airflow (Whitehead and Barefoot, 1980), intraoral air pressure (Hutchinson and Smith, 1976) and laryngeal gestures (Mahshie and Conture, 1983). Levitt and Stromberg (1983), analyzing corpora obtained from congenitally deaf children by Smith (1975) and Gold (1978Gold ( , 1980, list under "asynchrony errors" numerous substitutions of voiced for voiceless cognates.…”

“…Inadequate laryngeal activity of four normally hearing and four hearing-impaired persons was found during productions of word-initial voiced and voiceless consonants with a flexible fiberoptic laryngoscope [62]. Three of the hearing-impaired subjects exhibited greater variability than their normally hearing peers in terms of the degree and duration of vocal fold abduction during voiceless consonant productions, but only one exhibited excessively wide glottal openings, suggesting that deaf persons waste air during speech production.…”

The voice varies according to the context of speech and to the physical and psychological conditions of the human being, and there is always a normal standard for the vocal output. 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.
