We conducted a randomized control trial comparing two intensive treatments, voice (LSVT LOUD) or articulation (LSVT ARTIC) to assess single word intelligibility in the presence of background noise (babble and mall). Participants (64 PD and 20 Healthy) read words from the diagnostic rhyme test (DRT), an ANSI Standard for measuring intelligibility of speech, before and after one month (treatment or no treatment). Teams of trained listeners blindly rated the data. Speech intelligibility of words in the presence of both noise conditions improved in PD participants who had LSVT LOUD compared to the groups that had LSVT ARTIC or no treatment. Intensive speech treatment targeting prominent prosodic variables in LSVT LOUD had a positive effect on speech intelligibility at the single word level in PD.<\/jats:p>","DOI":"10.3390\/brainsci11070857","type":"journal-article","created":{"date-parts":[[2021,6,27]],"date-time":"2021-06-27T22:24:57Z","timestamp":1624832697000},"page":"857","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Single Word Intelligibility of Individuals with Parkinson\u2019s Disease in Noise: Pre-Specified Secondary Outcome Variables from a Randomized Control Trial (RCT) Comparing Two Intensive Speech Treatments (LSVT LOUD vs. LSVT ARTIC)"],"prefix":"10.3390","volume":"11","author":[{"given":"Geralyn","family":"Schulz","sequence":"first","affiliation":[{"name":"Department of Speech, Language, and Hearing Sciences, College of Arts and Sciences, George Washington University, Washington, DC 20052, USA"},{"name":"LSVT Global, Inc., Tucson, AZ 85705, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angela","family":"Halpern","sequence":"additional","affiliation":[{"name":"LSVT Global, Inc., Tucson, AZ 85705, USA"},{"name":"National Center for Voice and Speech-Denver, Denver, CO 80204, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer","family":"Spielman","sequence":"additional","affiliation":[{"name":"LSVT Global, Inc., Tucson, AZ 85705, USA"},{"name":"National Center for Voice and Speech-Denver, Denver, CO 80204, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorraine","family":"Ramig","sequence":"additional","affiliation":[{"name":"LSVT Global, Inc., Tucson, AZ 85705, USA"},{"name":"National Center for Voice and Speech-Denver, Denver, CO 80204, USA"},{"name":"Department of Communication Sciences and Disorders, Teachers College, Columbia University, New York, NY 10027, USA"},{"name":"Department of Speech, Language, and Hearing Sciences, College of Arts and Sciences, University of Colorado\u2014Boulder, Boulder, CO 80309, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ira","family":"Panzer","sequence":"additional","affiliation":[{"name":"Dynastat, Inc., Austin, TX 78731, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan","family":"Sharpley","sequence":"additional","affiliation":[{"name":"Dynastat, Inc., Austin, TX 78731, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katherine","family":"Freeman","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, Charles E.
