Recent studies suggest that these changes can be partially explained by altered sensory feedback processing in speech production: individuals with PD (IwPD) may fail to monitor and adapt sensory feedback when producing speech. We investigated PD voice production using a voice playback paradigm and focused on the sensory attenuation typically observed in event\u2010related responses (ERPs) to the self\u2010generated voice. When sensory feedback is intact, the P50, N100, and P200 responses to a self\u2010generated voice are attenuated compared to an externally generated voice. Twenty\u2010three IwPD and 23 matched healthy controls (HCs) completed the voice playback study with three conditions: self\u2010generated voice (auditory\u2010motor [AMC]), externally generated voice (auditory\u2010only [AOC]), and motor\u2010only. Linear mixed models assessed group differences in ERP morphology. Groups differed in the N100 latency response: IwPD showed a greater shift in latency between AMC and AOC than healthy controls. Regarding the P200, a significant group\u2010by\u2010condition interaction indicated that IwPD, unlike healthy controls, produced larger amplitudes for the self\u2010generated than the passively listened to voice. Taken together, these findings suggest that the processing of one's own voice in IwPD is altered in terms of temporal precision rather than in the N100 suppression effect per se. This effect was accompanied by an enhanced P200 attentional response. These response patterns in IwPD are indicative of likely progressing difficulties in regulating one's own voice, characteristic of Parkinson's disease.<\/jats:p>","DOI":"10.1111\/ejn.70700","type":"journal-article","created":{"date-parts":[[2026,10,15]],"date-time":"2026-10-15T04:19:05Z","timestamp":1792037945000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Altered Timing of Self\u2010Voice Processing in Parkinson's Disease"],"prefix":"10.1111","volume":"64","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5766-8616","authenticated-orcid":false,"given":"Francisco","family":"Contreras\u2010Ruston","sequence":"first","affiliation":[{"name":"Center for Music in the Brain, Department of Clinical Medicine Aarhus University and the Royal Academy of Music Aarhus\/Aalborg  Aarhus Denmark"},{"name":"Department of Neuropsychology and Psychopharmacology, Faculty of Psychology and Neuroscience Maastricht University  Maastricht the Netherlands"},{"name":"Department of Cognition, Development and Educational Psychology University of Barcelona  Barcelona Spain"},{"name":"Speech\u2010Language Pathology and Audiology Department \u2013 Universidad de Valpara\u00edso  San Felipe Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3192-441X","authenticated-orcid":false,"given":"Antonio","family":"Criscuolo","sequence":"additional","affiliation":[{"name":"Department of Neuropsychology and Psychopharmacology, Faculty of Psychology and Neuroscience Maastricht University  Maastricht the Netherlands"},{"name":"Max Planck Institute for Biological Cybernetics  T\u00fcbingen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Call\u00e9n","sequence":"additional","affiliation":[{"name":"Neurology Department Parc Sanitari Sant Joan de D\u00e9u  Sant Boi de Llobregat Barcelona Spain"},{"name":"Institut de Recerca Sant Joan de D\u00e9u  Esplugues de Llobregat Barcelona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Cucurell","sequence":"additional","affiliation":[{"name":"Department of Cognition, Development and Educational Psychology University of Barcelona  Barcelona Spain"},{"name":"Cognition and Brain Plasticity Unit, Neuroscience Program Institut d'Investigaci\u00f3 Biom\u00e8dica de Bellvitge (IDIBELL)  L'Hospitalet de Llobregat Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jordi","family":"Navarra","sequence":"additional","affiliation":[{"name":"Department of Cognition, Development and Educational Psychology University of Barcelona  Barcelona Spain"},{"name":"Institute of Neurosciences, Universitat de Barcelona  Barcelona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sonja A.","family":"Kotz","sequence":"additional","affiliation":[{"name":"Department of Neuropsychology and Psychopharmacology, Faculty of Psychology and Neuroscience Maastricht University  Maastricht the Netherlands"},{"name":"Department of Neurology Max Planck Institute for Human Cognitive and Brain Sciences  Leipzig Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,14]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0191839"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1044\/2020_JSLHR-20-00003"},{"key":"e_1_2_12_4_1","doi-asserted-by":"crossref","unstructured":"Abur D.
