Domestic dogs (Canis lupus familiaris) are sensitive to the correlation between pitch and timbre in human speech (2021)
Journal Article
Sturdy, S., Smith, D. R., & George, D. N. (in press). Domestic dogs (Canis lupus familiaris) are sensitive to the correlation between pitch and timbre in human speech. Animal Cognition, https://doi.org/10.1007/s10071-021-01567-4

The perceived pitch of human voices is highly correlated with the fundamental frequency (f0) of the laryngeal source, which is determined largely by the length and mass of the vocal folds. The vocal folds are larger in adult males than in adult femal... Read More about Domestic dogs (Canis lupus familiaris) are sensitive to the correlation between pitch and timbre in human speech.

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...

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...

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), Article 2041669516671320. 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 about Speaker-sex discrimination for voiced and whispered vowels at short durations.

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...
