LSVT Global has partnered with Google on an exciting project called Project Euphonia to help improve automatic speech recognition software for people with speech impairments. These speech impairments may make using devices like Siri, Alexa, or speech-to-text frustrating. To do this, we need samples of disordered speech to train the system. LSVT Global is recruiting people with speech disorders to help!

This study presents the first randomized controlled trial (RCT) examining the effects of two speech treatment approaches, LSVT LOUD and LSVT ARTIC, on voice quality in individuals with Parkinson’s disease (PD). Both treatments were identical in how intensive they were, but LSVT LOUD targeted healthy loudness, whereas LSVT ARTIC focused on articulation. Additionally, an untreated group of individuals with PD also participated in the study, and a group of 20 individuals without PD were included to examine differences in voice quality at pre-treatment.

This study looked at speech and brain changes in individuals with Parkinson’s disease following two speech treatment approaches, matched for intensity of dosage (16, 1-hour individual sessions in one month) but differing on treatment target, loudness (LSVT LOUD) or articulation (LSVT ARTIC). A group of untreated individuals with Parkinson’s disease were also studied as a comparison group. All participants were evaluated at baseline, post-treatment (one month after baseline), and seven months after baseline to help identify both short-term and long-term changes.

Based on this initial study, we have enough proof to continue to establish higher levels of treatment evidence that LSVT LOUD has a positive therapeutic effect on voice and speech in children with DS. We hope to conduct a larger treatment study and include a wider age-range of children and youth with DS.

One key takeaway is that pre-treatment protocols can be designed and implemented to give children who are otherwise deemed unable to participate in LSVT LOUD a chance to train and prepare for the gold-standard protocol which may open the door to functional communication and the chance to have some control of their speech.

My client felt so elated with her outcomes that she wanted to spread the word! Her neurological voice disorder has not been cured, but positive, functional changes resulted from the intensive LSVT LOUD program. Our hope is that future research will support the application of LSVT to the ABSD population as a functional treatment approach.

Results showed that speech intelligibility of words in the presence of both noise conditions improved in participants with Parkinson’s who had LSVT LOUD compared to the groups that had LSVT ARTIC or no treatment. The ability to be understood can improve the quality of life for people with PD and this is really what the goal of any therapy should be, so it is exciting to be able to report these results.
