Speech Characteristics of Childhood Apraxia of Speech in Hebrew-Speaking Children

Abstract

Highlights What are the main findings? Israeli speech–language pathologists identified inconsistent errors, difficulty with multisyllabic words, and syllable sequencing difficulties as the most common and diagnostically informative characteristics of childhood apraxia of speech. Prosodic features, particularly lexical stress errors, were perceived as relatively uncommon and less diagnostically informative in Hebrew-speaking children with childhood apraxia of speech. What are the implications of the main findings? The findings suggest that some clinical manifestations of childhood apraxia of speech may be influenced by language-specific phonological and prosodic properties. Cross-linguistic evidence should inform the development of language-appropriate diagnostic frameworks and assessment tools for childhood apraxia of speech. Abstract Purpose: Childhood apraxia of speech (CAS) is a motor speech disorder characterized by deficits in speech planning and programming. However, current diagnostic frameworks have been developed primarily from studies of English-speaking children, raising questions regarding their applicability to other languages. This study examined the common and diagnostic speech characteristics of Hebrew-speaking children with CAS as perceived by Israeli speech–language pathologists (SLPs). Method: Two hundred Israeli SLPs with experience diagnosing and/or treating children with CAS completed an online questionnaire. Participants rated 26 speech characteristics on 7-point scales reflecting their perceived frequency and diagnostic specificity in Hebrew-speaking children with CAS. Descriptive analyses included mean ratings and the percentage of clinicians endorsing each characteristic. Results: Increased difficulty with multisyllabic words (M = 6.37) and inconsistent errors (M = 6.32) received the highest frequency ratings and were endorsed by 87.0% and 84.0% of clinicians, respectively, as common characteristics of CAS. Inconsistent errors received the highest diagnostic specificity rating (M = 6.12), followed by groping movements (M = 5.73) and difficulty sequencing syllables (M = 5.48). Prosodic features, including lexical stress errors (M = 3.72) and equal stress patterns (M = 3.73), received ratings at or below the midpoint of the scale and were endorsed by fewer than 20% of clinicians as common characteristics of CAS. Breathy voice (M = 3.11) and consistent hypernasality (M = 2.79), two control characteristics not typically associated with CAS, received the lowest ratings. Conclusions: Israeli SLPs identified syllable sequencing difficulties and inconsistency as the most salient and diagnostically informative characteristics of CAS in Hebrew-speaking children. In contrast, prosodic features, particularly lexical stress errors, were perceived as less common and less central to diagnosis than suggested by English-based diagnostic frameworks. These findings suggest that the clinical manifestation of CAS may be influenced by language-specific phonological and prosodic properties and underscore the need for direct investigation of CAS characteristics in Hebrew-speaking children.
