Research laboratory background

Advancing Research in Motor Speech Disorders

The Speech Production Lab (SPL) is housed in the Department of Speech-Language Pathology at Temerty Faculty of Medicine, University of Toronto and is directed by Prof. Yana Yunusova. Our lab is dedicated to the study of normal and disordered aspects of speech motor control and to innovation in the assessment and rehabilitation of individuals with neurologic and neurodegenerative disorders affecting speech and orofacial motor control.

Our Research

Exploring the complexities of motorspeech disorders through rigorous scientific inquiry and clinical innovation.

The Development and Validation of a Novel Tool for the Assessment of Bulbar Dysfunction in ALS
This project addresses the need for improved clinical assessments of bulbar dysfunction in ALS by creating and validating a clinician-administered tool - the ALS-Bulbar Dysfunction Index (ALS-BDI). The ALS-BDI translates prior research knowledge and multidisciplinary expert consensus into a clinically-meaningful tool for Speech Language Pathologists (SLPs) to use in their clinical practice.

ActiveALS Canada-Brain Canada
Development of a Shared Decision-making Aid for Bulbar Symptom Management in ALS
This project aims to develop a tool to facilitate decision-making conversations about bulbar symptom management between patients with ALS, their families, and healthcare professionals throughout disease progression. It aims to promote a person-centered and standardized approach to ALS care by supporting decisions that better reflect the needs of patients and their families in their daily lives.

Strengthening Oropharyngeal Muscles as a Novel Approach to Treat Obstructive Sleep Apnea
Oropharyngeal exercises have emerged as a therapeutic option for treating obstructive sleep apnea (OSA) in neurotypical adults and those who suffered a stroke. These exercises deal directly with the underlying mechanism of OSA by improving the sensorimotor function of the upper airway muscles. We developed the OPEX app to deliver oropharyngeal exercises to individuals with OSA at home.

Machine Learning in the Detection of Upper and Lower Motor Neuron Features in Speech of Patients with ALS
The purpose of this project is to develop a tool that allows identification of upper motor neuron and lower motor neuron features in speech in patients with bulbar dysfunction due to these neurodegenerative diseases. We use novel ML/AI methods to detect speech features characteristic of these phenotypes and track progression of changes over time.
