Disordered speech and voice may limit access to everyday voice activated devices (e.g., mobile phones, computers). These devices have automatic speech recognition (ASR) systems that have been trained on non-disordered speech. This makes it frustrating for individuals with speech disorders such as those accompanying Amyotropic lateral sclerosis (ALS), Down Syndrome and Parkinson’s disease (PD) to utilize these devices. Project Euphonia is an initiative by Google to make speech technology more accessible to individuals with non-standard speech. The first step in this process is to gather large numbers of speech samples from disordered speakers in order to train speech recognition systems. This paper reports initial work to collect speech data from individuals with PD to contribute to this project. 

Given the role of voice in language expression, we pose that optimizing vocal function may lead to improved language production. Verbs are often impaired in individuals with PD and it is thought that damage to the motor system, given its connection action verbs, underlies this lexical effect. If this is the case, then treatment improving vocal motor function may also improve access to action verbs. Following an intensive 4-week voice treatment, individuals with PD produced fewer utterances and had decreased mean utterance length, but they also produced more words, morphemes and verbs per utterance. Thus, intervention improving vocal loudness was associated with improved verb use and production of more complex syntax in PD. 

For years, in-person group exercise classes for people with PD following LSVT LOUD and LSVT BIG treatments have been offered as a motivating way to encourage maintenance of treatment gains. During COVID-19, stay at home orders eliminated access to classes for many. This seminar will present our detour from in-person to virtual teleLOUD for LIFE and teleBIG for LIFE classes. Practical application of technology, guidelines for delivery, and feedback from participants will be presented.

This session will (a) examine how speech therapists are using an evidence-based, Parkinson’s specific treatment (LSVT LOUD) in atypical parkinsonism, other movement disorders, aging conditions and childhood/adolescent populations, and (b) explore therapists’ perceived outcomes and challenges in applying LSVT LOUD beyond Parkinson’s disease. These clinical implementation data will inform needs for future research and ongoing clinical support for therapists.

This study explores the acoustic and perceptual consequences of the Lee Silverman Voice Treatment (LSVT LOUD®) in two adults (a female and a male) with cerebral palsy. The session describes the tenets of this intensive speech treatment and analyzes the impact of increased loudness on the vocal function of these two speakers. Positive changes were found in most of the acoustic measures examined, as well as in the perceptual data, following treatment. Together with the perceptual data and previous positive outcomes of LSVT LOUD applied to CP, these findings motivate continued research in this area.

This session will describe the implementation of telepractice in the treatment of adults with aphasia, traumatic brain injury (TBI) and Parkinson’s disease (PD). The focus will be on the establishment of successful and sustainable telepractice programs in private practice and university clinic settings. Published outcome data will be reviewed supporting implementation of telepractice delivery of speech treatment for these populations and in these settings. A range of scenarios from successful US and international private and university clinics will be presented detailing considerations such as equipment, recruitment, challenges, solutions and reimbursement. Use of telepractice for screening, assessment and maintenance will be described. Special emphasis will be placed on sustainability of telepractice delivery of speech treatment for adult neurological populations.
