A Tool For Differential Diagnosis Of Childhood Apraxia Of Speech And Dysarthria In Children: A Tutorial, Jenya Iuzzini-Seigel, Kristen M. Allison, Ruth Stoeckel
Speech Pathology and Audiology Faculty Research and Publications
Purpose:
While there has been mounting research centered on the diagnosis of childhood apraxia of speech (CAS), little has focused on differentiating CAS from pediatric dysarthria. Because CAS and dysarthria share overlapping speech symptoms and some children have both motor speech disorders, differential diagnosis can be challenging. There is a need for clinical tools that facilitate assessment of both CAS and dysarthria symptoms in children. The goals of this tutorial are to (a) determine confidence levels of clinicians in differentially diagnosing dysarthria and CAS and (b) provide a systematic procedure for differentiating CAS and pediatric dysarthria in children.

Pediatric feeding disorders (PFDs) lack a universally accepted definition. Feeding disorders require comprehensive assessment and treatment of 4 closely related, complementary domains (medical, psychosocial, and feeding skill-based systems and associated nutritional complications). Previous diagnostic paradigms have, however, typically defined feeding disorders using the lens of a single professional discipline and fail to characterize associated functional limitations that are critical to plan appropriate interventions and improve quality of life. Using the framework of the World Health Organization International Classification of Functioning, Disability, and Health, a unifying diagnostic term is proposed: “Pediatric Feeding Disorder” (PFD), defined as impaired oral intake that is …

Parallel Reference Speaker Weighting For Kinematic-Independent Acoustic-To-Articulatory Inversion, An Ji, Michael T. Johnson, Jeffrey J. Berry
Parallel Reference Speaker Weighting For Kinematic-Independent Acoustic-To-Articulatory Inversion, An Ji, Michael T. Johnson, Jeffrey J. Berry
Speech Pathology and Audiology Faculty Research and Publications
Acoustic-to-articulatory inversion, the estimation of articulatory kinematics from an acoustic waveform, is a challenging but important problem. Accurate estimation of articulatory movements has the potential for significant impact on our understanding of speech production, on our capacity to assess and treat pathologies in a clinical setting, and on speech technologies such as computer aided pronunciation assessment and audio-video synthesis. However, because of the complex and speaker-specific relationship between articulation and acoustics, existing approaches for inversion do not generalize well across speakers. As acquiring speaker-specific kinematic data for training is not feasible in many practical applications, this remains an important and …

Speech Pathology and Audiology Faculty Research and Publications
Childhood apraxia of speech (CAS) is a debilitating pediatric speech disorder characterized by varying symptom profiles, comorbid deficits, and limited response to intervention. Specific Language Impairment (SLI) is an inherited pediatric language disorder characterized by delayed and/or disordered oral language skills including impaired semantics, syntax, and discourse. To date, the genes associated with CAS and SLI are not fully characterized. In the current study, we evaluated behavioral and genetic profiles of seven children with CAS and eight children with SLI, while ensuring all children were free of comorbid impairments. Deletions within CNTNAP2 were found in two children with CAS but …
Reliance On Auditory Feedback In Children With Childhood Apraxia Of Speech, Jenya Iuzzini-Seigel, Tiffany P. Hogan, Anthony J. Guarino, Jordan R. Green
Reliance On Auditory Feedback In Children With Childhood Apraxia Of Speech, Jenya Iuzzini-Seigel, Tiffany P. Hogan, Anthony J. Guarino, Jordan R. Green
Speech Pathology and Audiology Faculty Research and Publications
Children with childhood apraxia of speech (CAS) have been hypothesized to continuously monitor their speech through auditory feedback to minimize speech errors. We used an auditory masking paradigm to determine the effect of attenuating auditory feedback on speech in 30 children: 9 with CAS, 10 with speech delay, and 11 with typical development. The masking only affected the speech of children with CAS as measured by voice onset time and vowel space area. These findings provide preliminary support for greater reliance on auditory feedback among children with CAS.
Learning outcomes: Readers of this article should be able to (i) …

The Marquette University Electromagnetic Articulography Mandarin Accented English (EMA-MAE) corpus provides kinematic and acoustic data from 40 gender and dialect balanced speakers representing 20 Midwestern standard American English L1 speakers and 20 Mandarin Accented English (MAE) L2 speakers, half Beijing region dialect and half are Shanghai region dialect. Three dimensional EMA data were collected at a 400 Hz sampling rate using the NDI Wave system, with articulatory sensors on the midsagittal lips, lower …
Sensorimotor Adaptation Of Speech Using Real-Time Articulatory Resynthesis, Jeffrey J. Berry, Cassandra North, Michael T. Johnson
Sensorimotor Adaptation Of Speech Using Real-Time Articulatory Resynthesis, Jeffrey J. Berry, Cassandra North, Michael T. Johnson
Speech Pathology and Audiology Faculty Research and Publications
Sensorimotor adaptation is an important focus in the study of motor learning for non-disordered speech, but has yet to be studied substantially for speech rehabilitation. Speech adaptation is typically elicited experimentally using LPC resynthesis to modify the sounds that a speaker hears himself producing. This method requires that the participant be able to produce a robust speech-acoustic signal and is therefore not well-suited for talkers with dysarthria. We have developed a novel technique using electromagnetic articulography (EMA) to drive an articulatory synthesizer. The acoustic output of the articulatory synthesizer can be perturbed experimentally to study auditory feedback effects on sensorimotor …

Speech Pathology and Audiology Faculty Research and Publications
Few electromagnetic articulography (EMA) datasets are publicly available, and none have focused systematically on non-native accented speech. We introduce a kinematic-acoustic database of speech from 40 (gender and dialect balanced) participants producing upper-Midwestern American English (AE) L1 or Mandarin Accented English (MAE) L2 (Beijing or Shanghai dialect base). The Marquette University EMA-MAE corpus will be released publicly to help advance research in areas such as pronunciation modeling, acoustic-articulatory inversion, L1-L2 comparisons, pronunciation error detection, and accent modification training. EMA data were collected at a 400 Hz sampling rate with synchronous audio using the NDI Wave System. Articulatory sensors were placed …
Speech Sensorimotor Learning Through A Virtual Vocal Tract, Jeffrey J. Berry, Cassandra North, Benjamin Meyers, Michael T. Johnson
Speech Sensorimotor Learning Through A Virtual Vocal Tract, Jeffrey J. Berry, Cassandra North, Benjamin Meyers, Michael T. Johnson
Speech Pathology and Audiology Faculty Research and Publications
Studies of speech sensorimotor learning often manipulate auditory feedback by modifying isolated acoustic parameters such as formant frequency or fundamental frequency using near real-time resynthesis of a participant's speech. An alternative approach is to engage a participant in a total remapping of the sensorimotor working space using a virtual vocal tract. To support this approach for studying speech sensorimotor learning we have developed a system to control an articulatory synthesizer using electromagnetic articulography data. Articulator movement data from the NDI Wave System are streamed to a Maeda articulatory synthesizer. The resulting synthesized speech provides auditory feedback to the participant. This …

Tracking Articulator Movements Using Orientation Measurements, An Ji, Michael T. Johnson, Jeffrey J. Berry
Tracking Articulator Movements Using Orientation Measurements, An Ji, Michael T. Johnson, Jeffrey J. Berry
Speech Pathology and Audiology Faculty Research and Publications
This paper introduces a new method to track articulator movements, specifically jaw position and angle, using 5 degree of freedom (5 DOF) orientation data. The approach uses a quaternion rotation method to accomplish this jaw tracking during speech using a single senor on the mandibular incisor. Data were collected using the NDI Wave Speech Research System for one pilot subject with various speech tasks. The degree of jaw rotation from the proposed approach is compared with traditional geometric calculation. Results show that the quaternion based method is able to describe jaw angle trajectory and gives more accurate and smooth estimation …

A Comparison Of Adult- And Peer-Mediated Intervention For Autism: A Case Study, Maura Jones Moyle
Speech Pathology and Audiology Faculty Research and Publications
This study examined the response of a young child with autism to two play-based intervention conditions: adult-mediated and peer-mediated. The client was five years old, demonstrated moderate-to-severe autism, and exhibited developmental functioning between the 14 to 34 month level. The peer-mediated condition, based on a modified Integrated Play Group approach, utilized a typically developing peer who was three years of age. The study utilized an ABAB alternating treatment design to compare the impact of the adult- and peer-mediated interventions. Results from the current study suggest that the adult-mediated intervention resulted in increased engagement and more sophisticated social-communicative behaviors than the …
Speaking Rate Effects On Normal Aspects Of Articulation: Outcomes And Issues, Jeffrey J. Berry
Speaking Rate Effects On Normal Aspects Of Articulation: Outcomes And Issues, Jeffrey J. Berry
Speech Pathology and Audiology Faculty Research and Publications
The articulatory effects of speaking rate have been a point of focus for a substantial literature in speech science. The normal aspects of speaking rate variation have influenced theories and models of speech production and perception in the literature pertaining to both normal and disordered speech. While the body of literature pertaining to the articulatory effects of speaking rate change is reasonably large, few speaker-general outcomes have emerged. The purpose of this paper is to review outcomes of the existing literature and address problems related to the study of speaking rate that may be germane to the recurring theme that …

Speech Pathology and Audiology Faculty Research and Publications
In the United States, more than 2 million children in Grades pre-K through 6 speak Spanish as their primary language. Approximately 50% of these students receive academic instruction in Spanish. This tutorial provides research-based recommendations for presenting phonological awareness tasks to children who receive literacy instruction in Spanish. The authors also discuss how phonological awareness development may differ between monolingual children learning Spanish and monolingual children learning English, and the implications of these differences for choosing appropriate phonological awareness tasks for Spanish speakers.
