The face is excessively concave with very poor orthodontic-surgical prognosis. Services on Demand Journal. This microphone was connected to an audio capture plate Sound Blaster Audigy 2 installed in a computer, in which the audio recordings were saved in files in WAV format, using the software Anterikr Sound Forge, version 8.

It was decided to use sentences with recurrence of the same phoneme, since this recurrence might favor the auditory perceptual identification of the presence or absence of speech distortion. Int J Pediatr Otorhinolaryngol. This study was approved by the Institutional Review Board of the Hospital for Rehabilitation of Craniofacial Anomalies under protocol n. Occurrence of lisping in voiced and unvoiced fricatives in children with operated cleft lip and palate. This study also evidenced the influence of speech sample selection in the auditory perceptual judgment, since the fricative [s] tends to favor the identification of lisping when compared with its voiced counterpart [z].

It should be highlighted that the speech-language pathologists were not asked to characterize the type of lisping, but rather to identify its presence or absence at least in one fricative segment that constituted each of the two phrases, based on the auditory judgment.

In general, the literature reports that, when the mandible is protruded in relation to the maxilla, the tongue may be anteriorly positioned at rest, yielding changes in the airflow during production of alveolar fricatives, which would cause distortion in the production of these consonants. From This Paper Figures, tables, and topics from this paper. Effects of fixed labial orthodontic appliances on speech sound production.

Also, selection of the phonetic-phonological context of the word may allow the patient a greater perception of lisping, which may favor the therapeutic process when searching for contrast between the presence and absence of this deviation in speech.

Even though the Angle classification is among the most known and used for the evaluation of malocclusion in individuals without craniofacial malformations, this classification considers only the interarch tooth positioning in sagittal direction, besides being considered a qualitative rather than a quantitative malocclusion index Conversely, score 5 is characterized by a negative overjet with buccally tipped incisors; b bilateral crossbite; and c poor maxillary dental arch morphology and palate anatomy Figure 2.

February 19, ; Accepted: This occlusal index has been applied in many craniofacial centers because it is reliable and easily reproduced; is able to distinguish the quality of intercenter surgical outcomes, allowing early diagnosis of dental arch relationship in both anteroposterior, vertical and transverse dimensions; and provides identification of the prognosis, which allows early changes in the surgical protocol without the need to wait up to the permanent dentition Middle ear disease in children with cleft palate — protocols for manegement.

Appraisal of speech defects in dental anomalies. Abnormal patterns of tongue-palate contact in the speech individuals with cleft palate. A study of speech, language, hearing, and dentition in children with cleft lip only. This study evidenced that the selection of fricative consonants interfered with the auditory perception of lisping, with greater occurrence of lisping in the alveolar fricative [s] compared to [z].

Speech defect and orthodontics: The literature reports the importance of ultrasonography 32 and electropalatography 33 — 35 for better understanding of the pathological speech involving fricative consonants, including those related with cleft lip and palate However, so far, it has not been investigated whether these acoustic characteristics may influence the auditory perceptual judgment of lisping in the speech of individuals with craniofacial malformations, making its identification less audible in voiced compared with unvoiced fricatives.

The hypothesis initially adopted in this study is that lisping, when present, presents differently in voiced and unvoiced fricatives, with greater occurrence for unvoiced compared with voiced alveolar fricatives. Note the poor interarch relationship with negative overjet and normal inclination of maxillary incisors, bilateral crossbite, tendency to open bite at the cleft area and face tending to Angle Class III, with evident maxillary deficiency.

Considering the occurrence of differences in tongue root positioning between voiced and unvoiced fricatives in the production of normal speakers, this difference is also expected, though less marked, in the presence of lisping in which there is variability in anetrior production of fricatives. The study excluded children with history or presence of hypernasality, nasal air escape, weak intraoral pressure or compensatory articulation, at least to partially control the variables that might affect the identification of speech sound distortions.

Long-term outcomes of speech therapy for seven adolescents with visual feedback technologies: At completion, a single judgment anterkor obtained for each of the two consecutively repeated phrases, yielding a total of 64 judgments 32 related to the phrase composed of [s] and 32 related to the phrase composed of [z].

Previous studies on individuals without craniofacial malformations indicated that occlusal changes may cause damage to the production of alveolar fricative consonants 18 — 12even though this relationship is not always observed 13 or even may not be directly related to anerior severity of occlusal alteration Butcher European journal of orthodontics antreior Thus, this study investigated whether lisping, when present, differs between voiced and unvoiced alveolar fricatives produced by children with operated cleft lip and palate.

Donris In general, the literature reports that, when the mandible is protruded in relation to the maxilla, the tongue may be anteriorly positioned at rest, yielding changes in the airflow during production of alveolar fricatives, which would cause distortion in the production of these consonants. This microphone was connected to an audio capture plate Sound Blaster Audigy 2 installed in a computer, in which the audio recordings were saved in files in WAV format, using the software Sony Sound Forge, version 8. After listening anterlor each sentence, the speech-language pathologists indicated one alternative target or lisping for each speech sample analyzed, in a worksheet especially designed for that purpose. Vertical interincisal trespass assessment in children with speech disorders. Therefore, it may be suggested that articulatory differences between [s] and [z] may also occur in the presence of lisping, yet to a lower degree for [z], allowing greater auditory perception compared with [s]. This evaluation revealed a tendency of more anterior tongue root positioning in voiced fricatives compared to the unvoiced counterparts Occurrence of lisping in voiced and unvoiced fricatives in children with operated cleft lip and palate. A study of speech, language, hearing, and dentition in children with cleft antsrior only.

Vot When the judgments of lisping were compared between the fricatives produced, a significant increase in lisping was observed for the alveolar fricative [s] compared with the amterior fricative [z]. Conversely, interruptions or restrictions of the airflow in voiced fricatives reduce the airflow volume and consequently the intensity of turbulence at the constriction point.

Acoustically, voiced fricatives are characterized by the presence of two sources, the glottal source responsible for voicing and the noise source resulting from constriction of the vocal tractwhile unvoiced fricatives are formed by a single noise source 7.

ABSTRACT Purpose to investigate whether lisp, when identified, differs between voiced and unvoiced alveolar fricatives produced by children with cleft palate. Malocclusion traits and articulatory components of speech. Studies using magnetic resonance imaging also revealed differences in tongue positioning during the production of unvoiced and voiced fricatives.
