Comparison of Traditional Articulation Therapy and Picture Articulation Test in Children with Articulation Disorders

Background: Articulation disorders in children can impede communication and social interaction. Traditional Articulation Therapy (TAT) and the Picture Articulation Test (PAT) are two contrasting approaches employed to address these disorders. While TAT is a conventional method focusing on sensory-perceptual training and sound stabilization, PAT uses visual aids to assess and encourage correct speech sound production. Objective: The study aimed to evaluate and compare the efficacy of TAT and PAT in treating substitution errors in children with articulation disorders. Methods: Employing a randomized sampling technique, the study included 10 children with functional articulation disorders, aged 8 to 18 years, from both genders. Exclusion criteria included organic articulation disorders. Participants were divided into two groups at REX Medical Center, Lahore, and treated over a six-month period, with two sessions per week lasting 30-40 minutes. Pre- and post-intervention assessments were conducted using the Articulation Assessment Test and the Articulation Severity Rating Scale. Data analysis was performed using SPSS 24, with paired and independent sample t-tests. Results: TAT showed a significant reduction in substitution error scores from pre- to post-intervention across all error types (initial, middle, and final), with significant p-values indicating improvement (p ≤ 0.05). PAT did not demonstrate a significant reduction in error scores, with p-values exceeding the threshold of significance. Conclusion: TAT was found to be more effective than PAT in decreasing substitution errors in children with articulation disorders. The findings advocate for the application of TAT in clinical settings, while recognizing the potential for integrating traditional methods with newer technologies to optimize treatment outcomes.

Specific Articulation Disorders in Children Native Speakers of Bulgarian – Distribution, Characteristics, Demographic Patterns

The article presents a study of the articulation behaviour in 610 Bulgarian children aged 4 years and 5 months up to 7 years and 6 months. In 503 children (82%), incorrect articulation of consonant sounds from early, middle and late ontogenesis is established. The highest percentage of non-normative production is registered with sounds of early ontogenesis [l] 79% and [r] 43%. The percentage distribution of impaired articulation of ontogenetically middle fricatives is 27% for the group of [ʃ], [ʒ], [tʃ] and 20% for the group of [s], [z], [ts] respectively. Incorrect articulation of the ontogenetically early sounds [k, g] is recorded in 1% of the subjects surveyed for the [k] sound and 4% for the [g] sound. What is observed is the presence of age dynamics of impaired articulation where the number of children without disorders tends to increase with age. Another factor of influence on the distribution of the articulation disorders to be noted is the demographic one, i.e. the place of residence. The results obtained show a significant difference in the number of registered articulation disorders in children living in the capital of Bulgaria (Sofia) and living in other places. The established differences are related to the lack of a comprehensivel state policy (health and education) for the organization of prevention, diagnosis and therapy of communicative disorders.

Audiovisual materials are effective for enhancing the correction of articulation disorders in children with cleft palate

IntroductionChildren with cleft palate frequently show speech disorders known as compensatory articulation. Compensatory articulation requires a prolonged period of speech intervention that should include reinforcement at home. However, frequently relatives do not know how to work with their children at home. ObjectiveTo study whether the use of audiovisual materials especially designed for complementing speech pathology treatment in children with compensatory articulation can be effective for stimulating articulation practice at home and consequently enhancing speech normalization in children with cleft palate. Materials and methodsEighty-two patients with compensatory articulation were studied. Patients were randomly divided into two groups. Both groups received speech pathology treatment aimed to correct articulation placement. In addition, patients from the active group received a set of audiovisual materials to be used at home. Parents were instructed about strategies and ideas about how to use the materials with their children. Severity of compensatory articulation was compared at the onset and at the end of the speech intervention. ResultsAfter the speech therapy period, the group of patients using audiovisual materials at home demonstrated significantly greater improvement in articulation, as compared with the patients receiving speech pathology treatment on – site without audiovisual supporting materials. ConclusionThe results of this study suggest that audiovisual materials especially designed for practicing adequate articulation placement at home can be effective for reinforcing and enhancing speech pathology treatment of patients with cleft palate and compensatory articulation.

Songs from the Outback: The Effectiveness of Music in Treating Articulation Disorders in Children Aged 2–5 Years with Cleft Palate and Velopharyngeal Dysfunction

The Royal Children's Hospital Speech Pathology Department (RCH SPD) provides services to children with Cleft Palate (CP) and velopharyngeal dysfunction (VPD) in a geographical region that is more than twice the size of Texas, with 30% of the children residing in regional areas. The geographical distribution of the population means that many families are unable to access local speech therapy. To address this problem, the RCH SPD and Music Therapy departments (MTD) collaborated to create a clinical resource for regional children and families. The package is intended to facilitate an increase in children's consonant inventory, frequency of vocalizations, vocabulary, and communicative opportunity and increase oral airflow during speech. It is also intended to facilitate family-centered care and increase the parent and child's motivation to participate in speech therapy activities within the home environment. The clinical resource has now been distributed to 70 children with cleft palate in Queensland. This paper presents results of preliminary evaluation of the program and explores the use of music to facilitate speech sound stimulation for children with CP and VPD aged 2–5 years. This resource will be of interest to speech therapists and families with limited or no access to services.

Longitudinal changes of formant values and vowel space in two Mandarin-speaking children before 9 years of age

Vowel productions of two Mandarin-speaking children were audio recorded in their homes with picture naming tasks once every 3 months, from birth to 9 years old. The present study is the ninth year of a longitudinal observation. Major findings in this stage are as follows: (1) The trend of decrease in formant values was continuously observed in the boy subject. As for the girl subject, it is not until 9 years old, the obvious decrease in formant values was found, especially in F1; (2) F1 values are more stable than F2 values in both subjects. They appeared to acquire jaw movement sooner than tongue movement; (3) Throughout these 9 years, the variability of F1 is around 200–300 Hz, and the variability of F2 is 500–700 Hz in both subjects. No trend of decrease was found; (4) The trend of shrinkage in F1-F2 vowel area continues from 7 to 9 years old for the boy subject, but not for the girl subject; (5) There is a clear decline in fundamental frequencies at 8-9 years of age in the boy subject. Longitudinal data of vowel formant values from the same group of subjects provide important references for assessment and treatment of articulation disorders in children.

Longitudinal formant analysis of Mandarin-learning children before 7 years of age.

The present study is the seventh year of a longitudinal observation of vowel production in two Mandarin-learning children. In addition to gender differences, both subjects at 7 years of age experienced a slow growth stage after a rapid growth period in previous stages. Major findings are (1) girl subject used vowels with nasal endings more frequently than boy subject; (2) decrease of F1 F2 values is not so evident as in the previous stages in boy subject. As to girl subject, up to 7 years of age, no obvious change in formant values was found; (3) F1 values are more stable than F2 values in both subjects, especially in corner vowels. They appeared to acquire jaw movement sooner than tongue movement; (4) the earlier trend of shrinkage in F1-F2 vowel area was not found at this stage, and extension of vowel space was even found in both subjects; (5) there is no obvious trend of f0 decline in both subjects. Longitudinal data of vowel formant values from the same group of subjects provide important references for assessment and treatment of articulation disorders in children.

Automatic detection of articulation disorders in children with cleft lip and palate

Speech of children with cleft lip and palate (CLP) is sometimes still disordered even after adequate surgical and nonsurgical therapies. Such speech shows complex articulation disorders, which are usually assessed perceptually, consuming time and manpower. Hence, there is a need for an easy to apply and reliable automatic method. To create a reference for an automatic system, speech data of 58 children with CLP were assessed perceptually by experienced speech therapists for characteristic phonetic disorders at the phoneme level. The first part of the article aims to detect such characteristics by a semiautomatic procedure and the second to evaluate a fully automatic, thus simple, procedure. The methods are based on a combination of speech processing algorithms. The semiautomatic method achieves moderate to good agreement (kappa approximately 0.6) for the detection of all phonetic disorders. On a speaker level, significant correlations between the perceptual evaluation and the automatic system of 0.89 are obtained. The fully automatic system yields a correlation on the speaker level of 0.81 to the perceptual evaluation. This correlation is in the range of the inter-rater correlation of the listeners. The automatic speech evaluation is able to detect phonetic disorders at an experts'level without any additional human postprocessing.

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.

A clinical note on articulation disorders in children

This is a review on 71 children with disorders of articulation, or“functional articulation disorders”seen in our speech clinic. The children were classified into two groups, group A and group B, according to the pattern of their articulation errors. Group A consisted of 32 children with articulation errors commonly found along the course of normal speech development. Group B involved 39 children showing different types of errors from those observed in normal development of speech. The observed results were summarized as follows.(1) Substitution of {t/k, d/g} and {t or t∫or∫/s, d or d _??_/dz} were typically found in group A, whereas in group B, there were various types of errors including lateral lisping type, glottal stop, nasal articulation and abnormal palatal articulation.(2) Affected sounds were more variable in group B as compared to group A. Errors for t∫, t, d, n, i, p and b were observed only in group B.(3) Spontaneous correction of the errors was obtained in some cases in group B as well as in group A for the age range of 4 to 6 years.(4) Articulation training achieved good results in both groups. However a longer time period of training was needed for group B in general, due to a greater number of errors to be corrected.(5) Correction of errors such as s/t, k/t, k/s, lateral lisping type and abnormal palatal articulation appeared to require longer time than that of other errors.(6) Application of distinctive feature analysis for the discription of articulation disorders was also discussed.
