Purpose: Vocal roughness is often present in many voice disorders but the assessment of roughness mainly depends on the subjective auditory-perceptual evaluation and lacks acoustic correlates. This study aimed to apply the concept of roughness in general sound quality perception to vocal roughness assessment and to characterize the relationship…

Introduction: Assessment of resonance characteristics is essential in research and clinical practice in individuals with velopharyngeal impairment. The purpose of this study was to systematically review correlations between auditory perceptual ratings and nasalance scores obtained by a nasometer in individuals with resonance disorders and to…

The purpose of this guidebook is to: (1) Assist Speech-Language Pathology service providers as they support the educational goals of eligible students with disabilities in the District of Columbia Public Schools (DCPS); and (2) Ensure that all Speech-Language Pathologists (SLPs) in the District of Columbia Public Schools (DCPS) operate with the…

Primary progressive aphasia (PPA) is an acquired neurodegenerative syndrome that has specific and devastating effects on an individual's speech and language ability. Based on a detailed assessment of behavior and cognition, combined with structural neuroimaging data and pathological evidence, PPA is typically classified into three variants: the…

Purpose: The goal of this study was to determine whether the results obtained from a 25-utterance conversational language sample were as reliable as those obtained from a 50-utterance sample. Method: Robust conversational language samples from 220 children with typically developing language (106 boys, 114 girls) ranging in age from 3;2 to 7;10…

Purpose: The purpose of this tutorial is to guide practitioners to a critical praxis of speech, language, and hearing. This tutorial provides a foundational knowledge of critical theory as an approach to framing, conceptualizing, and interpreting phenomena and demonstrates its application to the speech, language, and hearing profession. Method:…

Misrepresentation of culturally and linguistically diverse (CLD) students in special education is a continuing issue that requires attention. This is likely occurring due to educators' lack of knowledge, awareness, and/or training to work with diverse populations. The educational needs of CLD students require that schools, teachers, and staff…

Purpose: The algorithm of the Language ENvironment Analysis (LENA) system for calculating language environment measures was trained on American English; thus, its validity with other languages cannot be assumed. This article evaluates the accuracy of the LENA system applied to Korean. Method: We sampled sixty 5-min recording clips involving 38 key…

Background: We discuss a free software system (Computerized Language Analysis [CLAN]) that can enable fast, thorough, and informative language sample analysis (LSA). Method: We describe methods for eliciting, transcribing, analyzing, and interpreting language samples. Using a hypothetical child speaker, we illustrate use KidEval to generate a…

Second language (L2) researchers have long acknowledged the role of language anxiety in communication processes, such that learners with greater language anxiety tend to be less willing to engage in communication. However, little research has explored links between L2 speakers' perceptions of conversation and dynamic measures of anxiety.…

Purpose: Assessment of strained voice quality is difficult due to the weak reliability of auditory-perceptual evaluation and lack of strong acoustic correlates. This study evaluated the contributions of relative fundamental frequency (RFF) and mid-to-high frequency noise to the perception of strain. Method: Stimuli were created using recordings of…

Purpose: The purpose of this study was to examine the measurement structure of the linguistic features of speech-language pathologists' (SLPs) talk during business-as-usual therapy sessions in the public schools, and to test the longitudinal stability of a theorized dimensional structure consisting of quantity, grammatical complexity, and lexical…

The potential of speech technology to improve educational outcomes has been a topic of great interest in recent years. For example, automatic speech recognition (ASR) systems could be employed to provide kindergarten-aged children with real-time feedback on their literacy and pronunciation as they practice reading aloud. Within these systems,…

Procedures and practices that are ableist in the educational system have been long overlooked. Speakers having differing abilities than neurotypical or able-bodied individuals is often not something that is considered in basic course assessment tools. This is important to address because although there are institutional policies and procedures in…

Purpose: Spoken discourse analysis is commonly employed in the assessment and treatment of people living with aphasia, yet there is no standardization in assessment, analysis, or reporting procedures, thereby precluding comparison/meta-analyses of data and hindering replication of findings. An important first step is to identify current practices…
