Language And Speech neuroRehabilitation Lab (LASR lab)

Directors: Dallin Bailey, PhD, CCC-SLP; Nancy Haak, PhD, CCC-SLP; Lawrence Molt, PhD, CCC-A, CCC-SLP

Collaborators: Marisha Speights Atkins, PhD, CCC-SLP; Cheryl Seals, PhD, Department of Computer Science and Software Engineering

Description: The LASR lab is focused on developing new techniques and strategies for increasing the functional communication of persons with neurogenic communication disorders. Our team members have a variety of areas of expertise, including aphasia, fluency disorders, dementia, and motor speech disorders. Our research projects include investigations of speech and language functioning in typical speakers, as well as in speakers with neurologically-based disorders.

Please contact Dr. Dallin Bailey at for information regarding undergraduate research opportunities.

Areas of Research

  • Speech motor learning in healthy speakers and speakers with communication impairments
  • Interactions between speech production and event boundaries
  • Development and testing of treatments and treatment outcome measures for aphasia and apraxia of speech
  • QEEG measurement of cortical activity while listening to music
  • Music and cooperation in the care of people who have dementia
  • Using software to improve tracking of speech production accuracy and training of phonetic transcription
  • Abstract word processing (words with low concreteness) in healthy and disordered speakers
  • Verb processing in healthy and disordered speakers
  • Single-subject research design in communication disorders

Current Projects

  • The Role of Mental Simulation (Mental Rehearsal and Action Observation) in Speech Motor Learning in Healthy Adult Speakers: Behavioral and Kinematic Evidence
  • The Impact of Event Boundaries on Speech Production in Physical and Virtual Reality Environments (collaboration with Dr. Cheryl Seals of the Department of Computer Science and Software Engineering)
  • Improving Learning Outcomes in Phonetic Transcription Using Automated Software Tools (collaboration with Dr. Cheryl Seals)
  • Development of Software Tools for Automatically Scoring Phonetic Transcriptions
  • Evaluation of an Articulatory-Kinematic and Rate/Rhythm Control Treatment for Apraxia of Speech
  • Illustrating Communication Disorders: A Research-Quality Database of Normal and Disordered Speech (co-directed with Dr. Speights Atkins of the Auburn University Technologies for Speech-Language Research Lab)
  • QEEG Measurement of Cortical Activity Listening to Music with Sung Lyrics vs. Instrumental-only Music
  • Use of Music to Increase Cooperation in the Care of People who have Dementia
  • Methods for Eliciting Verbal Production of Verbs with Low Concreteness Ratings

Special Equipment

  • Electromagnetic articulography equipment (Carstens AG 501) for 3-D tracking of tongue and lip movements during speech
  • Oculus Rift S Virtual Reality (VR) headset
  • Eprime 2.0 experimental software with Chronos response box for millisecond precision for presentation and response time collection
