Speech Production & Perception Lab

Welcome to the Speech Production and Perception Laboratory!

Research in the Speech Production and Perception Laboratory examines speech performance in children and adults in languages including English, French, Korean, Spanish, and Mandarin, with special emphasis on the motor speech disorder of dysarthria. Under the direction of Erika S. Levy, Ph.D., Associate Professor and trilingual speech-language pathologist, this lab is affiliated with the Program in Communication Sciences and Disorders in the Department of Biobehavioral Sciences at Teachers College, Columbia University.

 

We are currently seeking adult volunteers to participate in a speech treatment study for children with disabilities!

Please email us at cpspeech@tc.columbia.edu for more information.

Goals

The goals of our research are to better understand patterns of speech production in individuals with motor speech disorders from various language backgrounds and to develop language-specific or more general remediation strategies, when needed, for increasing intelligibility. Children with motor speech disorders are particularly under-represented in speech treatment research. An aim of the Speech Production and Perception Lab is to contribute important scientific knowledge on effective techniques for improving speech intelligibility in children with dysarthria. We develop and test Speech Intelligibility Treatment (Levy, 2014; 2018), a dual-focus treatment designed to increase intelligibility. Findings from this project will serve as evidence on which to base clinical practice

We aim to recreate natural speech patterns as much as possible within the laboratory setting. A theme of this research has been the investigation of utterances in continuous speech, in which neighboring vowels and consonants affect each other’s pronunciation, as opposed to examining words in isolation. Our work informs educational and therapeutic approaches to speech learning and disorders in individuals of various language backgrounds.

We are currently recruiting children with and without cerebral palsy (4-17 years old) in order to assesss treatment techniques. Qualifying families will be paid $50 for their time and effort. Please contact us at cpspeech@tc.columbia.edu or (212) 678-8361 to see if your child may qualify.

Current Projects

1. Acoustic predictors of intelligibility changes in children with and without cerebral palsy
We are currently recruiting children with CP (4-17 years old) with and without speech disorders, as well as age- and gender-matched typically-developing children, to assess the effectiveness of treatment strategies. They will use different techniques for improving their speech communication. We will provide feedback to parents. All participant information is kept completely confidential. You will be paid $50 for your time and effort!!! Please contact us at cpspeech@tc.columbia.edu or (212) 678-8361 to see if your child may qualify. The study is directed by Prof. Erika Levy, Ph.D., CCC-SLP and Kyung Hae Hwang, M.S., CCC-SLP. It takes place at Teachers College, Columbia University (120th Street) and takes up to 2 hours. Funding is provided through an ASHFoundation Clinical Research Grant. (TC IRB Protocol #14-245 )


2. Effects of speech cues and Speech Intelligibility Treatment (SIT) on intelligibility and communicative participation in children with dysarthria due to cerebral palsy who speak English, French, or Korean


3. Effects of speech cues and LSVT LOUD (Ramig et al., 2001) on speech intelligibility in English-speaking, Mandarin-speaking, and Spanish-speaking adults with hypokinetic dysarthria due to Parkinson’s disease.

4. Impact of Moebius Syndrome on intelligibility and quality of life, and effects of speech cues
