Acoustic and perceptual effects of telephone transmission on vowel quality
Lawrence, Sophie; Nolan, Francis; McDougall, Kirsty (2008)This study investigates acoustic and perceptual effects of telephone transmission on the vowels /i:/, /ae/ and /u:/ in Standard Southern British English. The aim of the study was to determine whether the ‘telephone effect’ ... -
The acoustic character of fricated /t/ in Australian English: a comparison with /s/ and /ʃ/
McDougall, Kirsty; Jones, Mark J. (2009-11-12)Australian English /t/ has a fricative realisation in some contexts. The presence of an additional surface fricative in the language raises questions about potential merger and the maintenance of contrasts. An orthographic ... -
Assessing perceived voice similarity using multidimensional scaling for the construction of voice parades
McDougall, Kirsty (2013)In recent years forensic phoneticians, in consultation with psychologists and law enforcement officers, have put considerable effort into devising and refining procedures for preparing and conducting fair voice parades. ... -
The consistency of formant measurements in high quality audio data: the effect of agreeing measurement procedures
Duckworth, Martin; McDougall, Kirsty; de Jong, Gea; Shockey, Linda (2011)This study examines the inter-analyst robustness of formant frequency (F) measurements before and after agreeing a common measurement procedure. Three laboratories used the latest available version of the same formant ... -
The DyViS database: style-controlled recordings of 100 homogeneous speakers for forensic phonetic research
Nolan, Francis; McDougall, Kirsty; de Jong, Gea; Hudson, Toby (2009)The DyViS project (‘Dynamic Variability in Speech: a Forensic Phonetic Study of British English’) at the University of Cambridge has compiled a large-scale database of speech recordings which will be freely available for ... -
Effects of the telephone on perceived voice similarity: implications for voice line-ups
Nolan, Francis; McDougall, Kirsty; Hudson, Toby (2013)This study is relevant to forensic cases where an earwitness claims to be able to remember and identify a voice, and, more generally, to voice recognition. Given that a voice may have been heard over the telephone, it is ... -
Individual variation in the frication of voiceless plosives in Australian English: a study of twins’ speech.
Loakes, Deborah; McDougall, Kirsty (2010-04-20)This study is an acoustic–phonetic examination of variation in Australian English consonant production. Group and individual patterns in the rates of frication of the voiceless plosives /p t k/ in Australian English are ... -
Profiling fluency: an analysis of individual variation in disfluencies in adult males
McDougall, Kirsty; Duckworth, Martin (2017-12-31)Individual variation in non-fluency behaviour in normally fluent (NF) adults, is investigated. Differences among speakers in the usage of a range of features such as filled and silent pauses, sound prolongations, repetition ... -
Sound change and speaker identity: an acoustic study
de Jong, Gea; McDougall, Kirsty; Nolan, Francis (Springer Nature, 2007) -
Speaker-specific formant dynamics: an experiment on Australian English /aɪ/
McDougall, Kirsty (2004)Formant frequency dynamics are relevant to forensic speaker identification since they are determined by the shape and size of a speaker’s vocal tract and the way he or she configures the articulators for speech. This study ... -
Telephone transmission and earwitnesses: performance on voice parades controlled for voice similarity
McDougall, Kirsty; Nolan, Francis; Hudson, Toby (2016-02-01)The effect of telephone transmission on a listener's ability to recognise a speaker in a voice parade is investigated. A hundred listeners (25 per condition) heard 1 of 5 ‘target' voices, then returned a week later for a ...
