[Mild hearing loss in children with communication disorders].

The prevalence of MHL in 202, 1 to 6 year-old children with communication disorders who visited our clinic in 1991 was investigated. 1) 31% of the subjects had MHL bilaterally. The prevalence of MHL was 44% at age 1 year, 20% at age 2 years, 36% at age 3 years, 24% at age 4 years, 39% at age 5 years, 33% at age 6 years. 2) 88% of children with MHL had OME, 10% had mild sensorineural hearing loss, and 2% had cerminous plug. 3) The prevalence of MHL in children with mental retardation and autistic disorders was 9%, that with stuttering was 9%, that of OME accompanied by moderate and severe hearing disorders was 6%. 4) The primary causes in 191, except for those with stuttering, were as follows; the prevalence of MHL was 30%, that of mental retardation and autistic disorders was 24%, and that of articulation disorders was 28%. 5) On the other hand, the prevalence of MHL in children with retarded language development and articulation disorders was 30%, which was significantly higher than that of the other communication disorders. Accordingly, the results of this study suggest that MHL in early childhood greatly influences communication disorders.

The outcome of long-term follow-up after palatoplasty.

The speech outcome was studied retrospectively in 140 cleft-palate patients who underwent push-back palatoplasty. Velopharyngeal function and articulation disorders were evaluated serially at 4, 7, 10, and more than 10 years of age. On comparison of velopharyngeal function between 4 years of age and the most recent review (>10 years), it was unchanged in 90 patients (64.3 percent), whereas it showed deterioration in 14 patients and showed improvement in 8 patients. The other 28 patients underwent pharyngeal flap surgery; this group also included patients with functional deterioration. Changes of velopharyngeal function often occurred between 4 and 7 years of age but sometimes occurred after 10 years of age. Articulation disorders were observed in 49 subjects (35.0 percent) at 4 years of age. Many of the patients with glottal stop showed improvement from 4 to 7 years of age. Palatalized articulation showed less improvement than glottal stop (p < 0.01). The number of patients with articulation disorders decreased significantly between 4 years of age and the most recent review (p < 0.001). These findings suggest that speech does not become stable before 10 years of age and that patients with cleft palate should be carefully followed until they are beyond this age.

[Speech disorders in childhood].

The paper discusses the individual childhood speech disorders: articulation, phonation, and rhythm disorders as well as the dysfunction of speech. In addition to the causes of retarded speech development, the authors discuss especially childhood aphasias. As an all-important characteristic feature of childhood aphasia they give emphasis to the rapid regression of speech disorders as well as to the absence of a dependence upon the localization of the lesion. They also discuss the existing nomenclature. Also discussed were the congenital speech disorders for which they suggest the term "congenital abnormality of speech reception and expression".

Toward a better understanding of the perception of self-produced speech.

UNLABELLED: The subject of how humans hear their own voices while speaking has received sporadic attention. Previous investigations suggest that the voice is heard substantially via bone conduction, implying a different transfer function to the ear--perhaps a low-pass filter--than for purely air-conducted vocalizations. Determining the characteristics of the transfer function of self-produced speech might contribute to a better understanding of self-perception. Such information may have important implications for treating articulation disorders. The efficacy of training discrimination during the remediation of articulation disorders remains unclear, perhaps because clients are asked to discriminate either speech of others or recorded self-speech samples not readily recognized as their own. This study was conducted to determine preference for filtered self-monitored speech in a delayed feedback paradigm. Participants made immediate comparisons of their real-time speech to delayed-recorded filtered self-speech samples. Participants demonstrated a clear preference for low-pass filtered speech, supporting earlier findings, but we were unable to determine the transfer function itself. LEARNING OUTCOMES: As a result of this activity, the learner will be able to describe some reasons why an individual's tape recorded speech typically sounds different to him/her from his/her own, live speech. As a result of this activity, the learner will be able to describe some potential applications for an accurately-characterized transfer function for self-produced speech.

Patterns of auditory processing and articulation deficits in academically deficient juvenile delinquents.

Auditory processing deficits and articulation disorders were studied in a group of male juvenile delinquents. Significant auditory processing deficits were frequently observed and were significantly related to underachievement in reading, spelling, and arithmetic. In addition, articulation disorders were present in over 60% of the delinquent subjects. The results are interpreted to indicate that the evaluation of speech capabilities and auditory processing skills should be an integral part of treatment programs for delinquent populations. The importance of early intervention through identification and treatment of speech and language disorders in the early school period is supported.

Comparison of orosensory confusions of hearing and hearing-impaired adults.

The relation between orosensory perception and articulation in 38 normal hearing adults (mean age = 20.1 yr.) with no articulation problems and 63 hearing-impaired adults (mean age = 21.2 yr.) with articulation disorders was investigated. All adults were asked to identify as a visual-matching task the 20 National Institute of Dental Research orosensory forms with handles. Comparison of number and types of orosensory confusions of the participants showed no significant differences between the groups. Results could have been influenced by the test, the response sought, or the origin and nature of the articulation disorders of the hearing-impaired participants. Implications for further research are discussed.

Articulatory function and tongue mobility after surgery followed by radiotherapy for tongue and floor of the mouth cancer patients.

The aim of this study was to determine which of the following factors--size of the post-excisional defect, site of the defect and type of reconstruction--influence tongue mobility and articulation disorders after treatment for cancer of the tongue and floor of the mouth. A total of 60 patients, who had been evaluated at least 6 months after surgery followed by radiotherapy (60 Gy in 30 fractions), were evaluated. According to the size of the post-excisional defect patients were divided into two groups: (1) defect less than 5 cm (35); (2) defect more than 5 cm (25). Based on the localisation of the defect patients were also divided into two groups: (1) anterior tongue and/or floor of the mouth (30); (2) lateral tongue and/or floor of the mouth (25) and tongue base (5). According to the type of reconstruction patients were divided into three groups: partly reconstructed (18); reconstructed with locally available tissue--local flaps (27); and with pectoralis major myocutaneous (PMMC) flaps (15). Articulation proficiency was assessed through Articulation Test and tongue mobility through Tongue Mobility Test. According to results of this study, type of reconstruction followed by size of post-excisional defect seemed to be the most influential factor in tongue mobility and articulation disorders after the tongue and floor of the mouth cancer treatment. Site of the defect has no influence.

The use of electropalatography in the assessment and treatment of acquired motor speech disorders in adults: current knowledge and future directions.

Electropalatography (EPG) has been employed to measure speech articulation since the mid-1970s. This technique has predominately been used in experimental phonetic research and in the diagnosis and treatment of articulation disorders in children. However, there is a growing body of research employing EPG to diagnose and treat articulatory impairment associated with acquired motor speech disorder (MSD) in adults. The purpose of this paper was to (1) review the findings of studies pertaining to the assessment and treatment of MSDs in adults using EPG, (2) highlight current methodologies employed, and (3) discuss the potential limitations of EPG in the assessment and treatment of MSDs and examine directions for future applied research and treatment studies.

Activating articulation skills through theraplay.

Speech Theraplay, a method of remediation for children with articulation disorders, is described. The approach is based on parent-child interactions that are postulated to activate articulation acquisition. These interactions between parent and child were duplicated and intensified in the clinical setting. Target phonemes were embedded into spontaneous interactive play, both in isolation and in meaningful exchange. The results of a six-week study indicate improvement in the articulation abilities of six children with this method.

Tooth position and speech--is there a relationship?

Although it is widely accepted that teeth play an important role in speech production, the relationship between tooth position and speech remains controversial. This review paper examines the relevant studies and discusses the difficulties of scientific investigation in this area. The ability of patients to adapt their speech to compensate for abnormal tooth position is recognized, but the mechanisms for this adaptation remain incompletely understood. The overall conclusion is that while certain dental irregularities show a relationship with speech disorders, this does not appear to correlate with the severity of the malocclusion. There is no definitive proof that alteration of tooth position can improve articulation disorders.

An investigation of the efficacy of oral myofunctional therapy as a precursor to articulation therapy for pre-first grade children.

This study investigated the assumption that oral myofunctional services might facilitate remediation of articulation disorders. Subjects were ten 6-year-old elementary school children who exhibited both tongue-thrust behaviors and articulation errors. All subjects had equal service time for a 14-week period, half receiving articulation services only and the other half receiving oral myofunctional services prior to and in conjunction with articulation services. Results showed that children in both programs made essentially equal progress in correcting placement of tongue-tip sounds, remediating /s/ and /z/ misarticulation, and remediating general articulation errors. Only children who received oral myofunctional services remediated tongue-thrust behaviors.
