Article
Objective: People with dysphonia are judged more negatively than peers with normal vocal quality. This preliminary study aims to (1) investigate correlations between both auditory-perceptual and objective measures of vocal quality of dysphonic and non-dysphonic speakers and attitudes of listeners, and (2) discover whether these attitudes towards p...
Article
Introduction: Children born with cleft palate with or without cleft lip (CP±L) tend to use less oral pressure consonants and more glottal sounds in their babbling. The purpose of very early palatal repair (i.e., one-stage palatal closure prior to 6 months of age) is to make the palate functional before the onset of speech acquisition to reduce the...
Article
Purpose: This study investigated whether intonation is influenced by age and gender and obtained normative data for the intonation of Flemish (Belgian Dutch) speaking cis women and cis men in Flanders, Belgium, per age group. Method: A total of 105 cis women and 102 cis men were included and equally spread in five age groups by gender. Semi-stru...
Article
Purpose. This study investigated parents’ perceptions on two different speech therapy delivery models in children with a CP±L, namely an innovative high intensity speech intervention (i.e. HISI: 10 one-hour sessions divided over 2 weeks) and a low intensity speech intervention (i.e. LISI: 10 one-hour sessions divided over 10 weeks). Method. Twelve...
Article
Purpose. Speech-language pathologists usually apply a “one size fits all” approach to eliminate compensatory cleft speech characteristics (CSCs). It is necessary to investigate what intervention works best for a particular patient. This pilot study compared the effectiveness of two therapy approaches (a motor-phonetic approach and a linguistic-phon...
Article
Purpose. This study investigated the practice patterns of private community speech-language pathologists (SLPs) when treating children with a repaired cleft of the palate ± a cleft of the lip (CP±L). Practices were explored in terms of diagnostics and treatment focus, treatment dosage and experienced difficulties when treating children with a CP±L....
Article
Objective. To investigate the impact of living with a cleft lip and/or cleft palate (CL/P) on sociodemographic variables, quality of life, esthetics, life satisfaction, and social distress in Dutch-speaking adolescents and adults. Design. Cross-sectional study. Participants. Thirty Dutch-speaking participants with a CL/P with a mean age of 26.93 ye...
Article
Purpose. The purpose of this study was to compare the effect of speech intervention provided with a low intensity with speech intervention provided with a high intensity on the speech and health-related quality of life (HRQoL) in Dutch-speaking children with a cleft palate with or without a cleft lip (CP±L) between 4 and 12 years. Methods. A longit...
Article
Background. Speech disorders in children with a cleft palate with or without a cleft lip (CP±L) are complex given the magnitude of influencing factors. Providing intervention to eliminate these speech errors is often challenging. However, no study has yet investigated how speech-language pathologists (SLPs) perceive and experience this. Aims. The...
Article
Purpose. This study compared the inter- and intra-rater reliability of the percentage consonants correct metrics (PCC) and the probe scoring system between an experienced and a less experienced rater and between two experienced raters. In addition, these outcome measures’ ability to reflect changes following speech intervention was measured. Metho...

Background. To date, there seems to be no consensus on the long-term quality of life outcomes in patients living with a cleft of the lip and/or palate (CL/P) with regard to well-being and functioning. Some studies report a substantial influence of having a cleft while other studies report no influence of living with a cleft. The purpose of this stu...

Setting Referral hospital for patients with cleft lip and palate in Uganda. Participants Twenty-four English-speaking Ugandan children with a CP±L (15 boys, 9 girls, mean 8.4 years...
Article
Introduction: Poor word decoding skills and writing skills can impact job opportunities and psychosocial functioning. Despite the importance of identifying possible literacy problems for the child’s future performance, there seems to be no consensus on this topic in children with a cleft of the palate with or without a cleft of the lip (CP±L). The...
Article
Purpose. The purpose of this study was to compare the effect of two different speech therapy approaches, a traditional motor-phonetic approach and a linguistic-phonological approach, on the speech and health-related quality of life in Dutch-speaking children with a cleft palate with or without a cleft lip (CP±L) between 4 and 12 years old. Methods...
Article
Aims: Speech (i.e., resonance, nasal airflow and articulation) is one of the primary outcomes in individuals with a cleft of the palate with or without a cleft of the lip (CP±L). Therefore, it is highly important to obtain information regarding parental perceptions and expectations concerning speech therapy-related cleft care. Literature investigat...
Article
Background and aims In addition to anatomical and physiological problems, children with a cleft (lip and) palate (CP ± L) often face psychosocial difficulties. A complex interaction between patient and environment may induce these problems. Based on the literature, speech disorders may negatively influence a listener’s judgement of a speaker. There...
Article
Objectives: workshops and specialized training programs are often inaccessible for speech and language pathologists (SLPs) based in resource-limited countries given the lack of supply, the long travel distances and the excessive participation fees. To stimulate life-long learning opportunities for all, this study described and measured the effect o...
Article
Introduction: At present, there is growing interest in combined phonetic-phonological approaches to treat active speech errors in children with a cleft (lip and) palate (CP±L). Unfortunately, evidence for these type of speech interventions in this population is lacking. Therefore, the present study investigated the effectiveness of speech intervent...
Article
Aims: this study evaluated the effectiveness of different speech techniques (i.e. modification of speech rate and/or mouth opening) for the rehabilitation of hypernasality in children with a cleft palate with or without a cleft lip (CP±L). The impact of speech rate and/or mouth opening was investigated on both hypernasality and speech intelligibili...
Article
Introduction: Lipofill­ing of the up­per lip as sec­ondary treat­ment in pa­tients with a cleft lip (and palate) (CL ± P) has been pro­posed to im­prove pro­jec­tion and vol­ume es­pe­cially in pro­file view. The pur­pose of the pre­sent study was to doc­u­ment dif­fer­ences in func­tional (i.e. lo­gopaedic) and self-re­ported aes­thetic out­comes...

Several studies reported that pitch and articulation may vary according to a person’s sexual orientation. The purpose of this study was to investigate whether homosexual males also demonstrate differences in nasal resonance compared to heterosexual males. Speech samples of 30 self-identified homosexual males, 35 heterosexual males, and 34 heterosex...

Article
Background and aims. Studies evaluating health-related quality of life (HRQoL) in patients with cleft palate living in resource-limited countries such as Uganda are scarce. The VELO questionnaire evaluates the impact of speech (and swallowing) difficulties on the patient’s HRQoL. The aim was to evaluate an adapted English version of the VELO questi...
Article
Background/aims: In resource-limited countries, traditional models for speech therapy delivery are not adequate to reach all patients in need. In those countries, intensive speech therapy might be a solution. Preliminary results of previous research demonstrated that intensive speech therapy can be effective in the short term for patients living i...
Article
Objectives: Recently, the Velopharyngeal Insufficiency (VPI) Effects on Life Outcomes (VELO) questionnaire, which evaluates the impact of speech and swallowing difficulties on health-related quality of life (HRQoL) in patients with VPI (Skirko et al., 2012; 2013), was translated to Dutch (Bruneel et al., 2017). The purpose of this study was to eval...
Article
Introduction In health-care, current efforts focus on providing patient-centered care. Specifically for patients with velopharyngeal insufficiency, and by extent patients with cleft palate, the Velopharyngeal Insufficiency (VPI) Effects on Life Outcomes (VELO) questionnaire (Skirko et al., 2012; 2013) allows the clinician to map the impact of speec...
