Fourteen participants read sentences imagining a hard-of-hearing addressee or a friend in a casual social setting. Tones produced in clear speech had longer duration, higher intensity, and larger F0 values. This style effect was rarely modulated by tone, preceding tonal context, or syllable position, consistent with an overall signal enhancement strategy. Possible evidence for tone enhancement was observed only in one set of analysis for F0 minimum and F0 range, contrasting tones with low targets and tones with high targets.<\/jats:p>","DOI":"10.1121\/10.0025991","type":"journal-article","created":{"date-parts":[[2024,5,28]],"date-time":"2024-05-28T12:32:44Z","timestamp":1716899564000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["Clear speech effects in production of sentence-medial Mandarin lexical tones"],"prefix":"10.1121","volume":"4","author":[{"given":"Jack","family":"Rittenberry","sequence":"first","affiliation":[{"name":"Department of English, Louisiana State University , Baton Rouge, Louisiana 70803, USA jackrittenberry@gmail.com , ishport@lsu.edu"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2665-7951","authenticated-orcid":false,"given":"Irina A.","family":"Shport","sequence":"additional","affiliation":[{"name":"Department of English, Louisiana State University , Baton Rouge, Louisiana 70803, USA jackrittenberry@gmail.com , ishport@lsu.edu"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2024,5,28]]},"reference":[{"key":"2024052812323709700_c1","doi-asserted-by":"publisher","first-page":"434","DOI":"10.1044\/jshr.2904.434","article-title":"Speaking clearly for the hard of hearing.
