Moving into the information age : from records to Google Earth (2017)
Journal Article
Smith, D. (2017). Moving into the information age : from records to Google Earth. The naturalist, 142(1095), 151-156

Many of us are avid recorders of Yorkshire’ varied flora and fauna. Over a recording career of many years a single recorder can personally amass large data sets or, if involved with networks of similarly-minded people, groups of recorders can rapidly... Read More

Research support-oriented MATLAB learning: tackling difficult concepts and promoting personalised learning (2017)
Journal Article
Yang, C., & Smith, D. (2017). Research support-oriented MATLAB learning: tackling difficult concepts and promoting personalised learning. New Directions in the Teaching of Physical Sciences, 12(12), https://doi.org/10.29311/ndtps.v0i12.2402

This study investigated the acquisition of MATLAB programming skills by postgraduate students, and whether this learning was improved by research support-oriented teaching. Questionnaire surveys were given to academic staff asking about what they con... Read More

Speaker-sex discrimination for voiced and whispered vowels at short durations (2016)
Journal Article
Smith, D. R. (2016). Speaker-sex discrimination for voiced and whispered vowels at short durations. i-Perception, 7(5), https://doi.org/10.1177/2041669516671320

Whispered vowels, produced with no vocal fold vibration, lack the periodic temporal fine structure which in voiced vowels underlies the perceptual attribute of pitch (a salient auditory cue to speaker sex). Voiced vowels possess no temporal fine stru... Read More

Does knowing speaker sex facilitate vowel recognition at short durations? (2014)
Journal Article
Smith, D. R. R. (2014). Does knowing speaker sex facilitate vowel recognition at short durations?. Acta psychologica, 148(May), 81-90. https://doi.org/10.1016/j.actpsy.2014.01.010

A man, woman or child saying the same vowel do so with very different voices. The auditory system solves the complex problem of extracting what the man, woman or child has said despite substantial differences in the acoustic properties of their voice... Read More

How the Human Brain Recognizes Speech in the Context of Changing Speakers (2010)
Journal Article
Smith, D. (2010). How the Human Brain Recognizes Speech in the Context of Changing Speakers. Journal of Neuroscience, 30(2), (629 - 638). ISSN 0270-6474

We understand speech from different speakers with ease, whereas artificial speech recognition systems struggle with this task. It is unclear how the human brain solves this problem. The conventional view is that speech message recognition and speaker... Read More

Discrimination of speaker sex and size when glottal-pulse rate and vocal-tract length are controlled (2007)
Journal Article
Smith, D. R. R., Walters, T. C., & Patterson, R. D. (2007). Discrimination of speaker sex and size when glottal-pulse rate and vocal-tract length are controlled. The Journal of the Acoustical Society of America, 122(6), (3628-3639). doi:10.1121/1.2799507. ISSN 0001-4966

A recent study [Smith and Patterson, J. Acoust. Soc. Am. 118, 3177-3186 (2005)] demonstrated that both the glottal-pulse rate (GPR) and the vocal-tract length (VTL) of vowel sounds have a large effect on the perceived sex and age (or size) of a speak... Read More

Neural representation of auditory size in the human voice and in sounds from other resonant sources (2007)
Journal Article
von Kriegstein, K., Smith, D. R. R., Patterson, R. D., Ives, D. T., & Griffiths, T. D. (2007). Neural representation of auditory size in the human voice and in sounds from other resonant sources. Current biology : CB, 17(13), (1123-1128). doi:10.1016/j.cub.2007.05.061. ISSN 0960-9822

The size of a resonant source can be estimated by the acoustic-scale information in the sound [1-3]. Previous studies revealed that posterior superior temporal gyrus (STG) responds to acoustic scale in human speech when it is controlled for spectral-... Read More

Time to judge sex of speaker: effect of glottal-pulse rate and vocal-tract length
Presentation / Conference
Time to judge sex of speaker: effect of glottal-pulse rate and vocal-tract length

When listening to someone's voice: what stimulus duration is required to tell whether the person speaking is a man or a woman; what are the acoustic cues in speech that influence such judgements; and how does manipulations in these acoustic cues infl... Read More
