This document provides a brief commentary on Johnson, Huron and Collister's (2014) article entitled "Music and lyrics interactions and their influence on recognition of sung words: An investigation of word frequency, rhyme, metric stress, vocal timbre and repetition priming." The commentary is written from the point of view of someone who is not only a fellow researcher in the field, but also a former professional singer and singing teacher. It begins by summarizing a previous study by two of the authors and the research of two further teams of investigators in the field. It concludes by focusing on each of the authors' eight hypotheses, findings and discussion in turn.Submitted 2013 June 13; accepted 2013 July 22.
KEYWORDS: singing, words, recognition, commentaryTHE study reported by Johnson, et al. (2014) is a follow-up to Collister and Huron's (2008) investigation of the intelligibility of sung text in English. To summarize the background to that study, Smith and Scott (1980) and Benolken and Swanson (1990) reported that listeners find it hard to distinguish between different vowels when sung at high pitch by a trained soprano. Hollien, Mendes-Schwartz and Nielsen (2000) showed that even voice teachers, phoneticians and speech pathology students found it hard to identify vowels correctly when trained singers -male as well as female -sang too high, i.e. when the fundamental frequency of the voice reaches or exceeds the first formant. Collister and Huron reported that, in their study, listeners (neither expert musicians nor singers) had greater difficulty understanding sung text. Listeners were found mishearing more than seven times as many words when compared to spoken text. Three-quarters of the errors involved consonants. Collister and Huron noted that when listeners did not identify vowels correctly, they tended to hear monophthongs as diphthongs or, more often, confuse them with central vowels (for those who are not expert in linguistics, these -in addition to the example Johnson et al. give of hearing "beat" as "bet" -can be found at http://web.ku.edu/~cmed/ipafolder/vowels.html).
A HOT TOPICSung text intelligibility is currently something of a "hot" topic. To declare an interest: I am a member of another research team working in this field. Our starting point was, unsurprisingly, our own experiences of finding it hard to understand sung text, particularly when performed by unamplified opera singers as opposed to those using amplification, as in musical theatre, or performing operettas, such as those by the English Victorians Gilbert and Sullivan without amplification. First, we asked listeners, regardless of their musical background, for their views on the factors underlying intelligibility, or the lack of it (Fine & Ginsborg, 2007a). Next, partly on the basis of our own experience as singers and singing teachers, as well as Hollien et al.'s (2000) findings, we asked other singers and singing teachers for their views (Fine & Ginsborg, 2007b).Responses to our questionnaire informed the design...
