Validity of Off-the-Shelf Automatic Speech Recognition for Assessing Speech Intelligibility and Speech Severity in Speakers with Amyotrophic Lateral Sclerosis
Peer reviewed Peer reviewed

Gutz, Sarah E.; Stipancic, Kaila L.; Yunusova, Yana; Berry, James D.; Green, Jordan R. – Journal of Speech, Language, and Hearing Research, 2022
Purpose: There is increasing interest in using automatic speech recognition (ASR) systems to evaluate impairment severity or speech intelligibility in speakers with dysarthria. We assessed the clinical validity of one currently available off-the-shelf (OTS) ASR system (i.e., a Google Cloud ASR API) for indexing sentence-level speech…

Co-Occurrence of Hypernasality and Voice Impairment in Amyotrophic Lateral Sclerosis: Acoustic Quantification
Peer reviewed Peer reviewed
Direct linkDirect link
Eshghi, Marziye; Connaghan, Kathryn P.; Gutz, Sarah E.; Berry, James D.; Yunusova, Yana; Green, Jordan R. – Journal of Speech, Language, and Hearing Research, 2021
Purpose: Hypernasality and atypical voice characteristics are common features of dysarthric speech due to amyotrophic lateral sclerosis (ALS). Existing acoustic measures have been developed to primarily target either hypernasality or voice impairment, and the effects of co-occurring hypernasality-voice problems on these measures are unknown. This…

Tanchip, Chelsea; Guarin, Diego L.; McKinlay, Scotia; Barnett, Carolina; Kalra, Sanjay; Genge, Angela; Korngut, Lawrence; Green, Jordan R.; Berry, James; Zinman, Lorne; Yadollahi, Azadeh; Abrahao, Agessandro; Yunusova, Yana – Journal of Speech, Language, and Hearing Research, 2022
Purpose: Oral diadochokinesis (DDK) is a standard dysarthria assessment task. To extract automatic and semi-automatic DDK measurements, numerous DDK analysis algorithms based on acoustic signal processing are available, including amplitude based, spectral based, and hybrid. However, these algorithms have been predominantly validated in individuals…

Shellikeri, Sanjana; Green, Jordan R.; Kulkarni, Madhura; Rong, Panying; Martino, Rosemary; Zinman, Lorne; Yunusova, Yana – Journal of Speech, Language, and Hearing Research, 2016
Purpose: The goal of this study was to identify the effects of amyotrophic lateral sclerosis (ALS) on tongue and jaw control, both cross-sectionally and longitudinally. The data were examined in the context of their utility as a diagnostic marker of bulbar disease. Method: Tongue and jaw movements were recorded cross-sectionally (n = 33…

Spatiotemporal Coupling of the Tongue in Amyotrophic Lateral Sclerosis
Peer reviewed Peer reviewed
Direct linkDirect link
Kuruvilla, Mili S.; Green, Jordan R.; Yunusova, Yana; Hanford, Kathy – Journal of Speech, Language, and Hearing Research, 2012
Purpose: The primary aim of the investigation was to identify deficits in spatiotemporal coupling between tongue regions in amyotrophic lateral sclerosis (ALS). The relations between disease-related changes in tongue movement patterns and speech intelligibility were also determined. Methods: The authors recorded word productions from 11…

Classifications of Vocalic Segments from Articulatory Kinematics: Healthy Controls and Speakers with Dysarthria
Peer reviewed Peer reviewed
Direct linkDirect link
Yunusova, Yana; Weismer, Gary G.; Lindstrom, Mary J. – Journal of Speech, Language, and Hearing Research, 2011
Purpose: In this study, the authors classified vocalic segments produced by control speakers (C) and speakers with dysarthria due to amyotrophic lateral sclerosis (ALS) or Parkinson's disease (PD); classification was based on movement measures. The researchers asked the following questions: (a) Can vowels be classified on the basis of selected…

Breath-Group Intelligibility in Dysarthria: Characteristics and Underlying Correlates
Peer reviewed Peer reviewed
Direct linkDirect link
Yunusova, Yana; Weismer, Gary; Kent, Ray D.; Rusche, Nicole M. – Journal of Speech, Language, and Hearing Research, 2005
Purpose: This study was designed to determine whether within-speaker fluctuations in speech intelligibility occurred among speakers with dysarthria who produced a reading passage, and, if they did, whether selected linguistic and acoustic variables predicted the variations in speech intelligibility. Method: Participants with dysarthria included a…
