Fifteen Portuguese participants listened to real disyllabic words produced by four Portuguese speakers. Lexical choices, confidence scores, isolation points (IPs), and recognition points (RPs) were analyzed. Mixed effects models predicted that the first syllable and 70% of the total duration of the second syllable were needed for lexical choices to be above chance level. Fricatives' place, not voicing, had a significant effect on the percentage of correctly identified words. IP and RP values of words with postalveolar voiced and voiceless fricatives were significantly different.<\/jats:p>","DOI":"10.1121\/10.0020302","type":"journal-article","created":{"date-parts":[[2023,8,9]],"date-time":"2023-08-09T14:05:50Z","timestamp":1691589950000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["Identification of words in whispered speech: The role of cues to fricatives' place and voicing"],"prefix":"10.1121","volume":"3","author":[{"given":"Luis M.
