    Towards ordinal classification of voice quality features with acoustic parameters
    (ESSV, 2019-03-09) Schaeffler, Felix; Eichner, Matthias; Beck, Janet M.
    The human voice is capable of fine-grained variation that results in listener attributions of various psychological, social and biological factors. The complexity of this process is reflected in the number and richness of terms that are used to describe human voices. In this paper we argue that any application that attempts a mapping of the acoustic voice signal onto voice descriptor labels would benefit from an intermediate auditory-phonetic level. As a point of departure we explore the relationships between acoustic parameters and some specific perceptual features derived from Vocal Profile Analysis (VPA), a phonetically motivated voice quality analysis scheme. Perceptual analysis of voice samples from 133 speakers was carried out using VPA for three key phonation features (creakiness, whisperiness, harshness). We extracted eleven acoustic parameters from the samples and used stepwise linear regression to identify acoustic parameters with predictive value. Samples from female speakers were used to derive regression equations which were then used to predict VPA ratings of male voices. Results show significant predictors for all three phonation features and indicate that predictions for the three phonation types rely mainly on different parameters. If a tolerance of ± 1 scalar degree for the perceptual analysis is accepted, then classification accuracy lies at or above 90% for all three phonation features.

    Seeing Speech: an articulatory web resource for the study of phonetics [website]
    (University of Glasgow, 2015-04-01) Lawson, Eleanor; Stuart-Smith, Jane; Scobbie, James M.; Nakai, Satsuki; Beavan, David; Edmonds, Fiona; Edmonds, Iain; Turk, Alice; Timmins, Claire; Beck, Janet M.; Esling, John; Leplatre, Gregory; Cowen, Steve; Barras, Will; Durham, Mercedes
    Seeing Speech (www.seeingspeech.ac.uk) is a web-based audiovisual resource which provides teachers and students of Practical Phonetics with ultrasound tongue imaging (UTI) video of speech, magnetic resonance imaging (MRI) video of speech and 2D midsagittal head animations based on MRI and UTI data. The model speakers are Dr Janet Beck of Queen Margaret University (Scotland) and Dr John Esling of University of Victoria (Canada). The first phase of this resource began in July 2011 and was completed in September 2013. Further funding was obtained in 2014 to improve and augment this resource (this version) and to develop its sister site Dynamic Dialects. The website contains two main resources: An introduction to UTI, MRI vocal tract imaging techniques and information about the production of the articulatory animations. Clickable International Phonetic Association charts links to UTI, MRI and animated speech articulator video. This online resource is a product of the collaboration between researchers at six Scottish Universities: The University of Glasgow, Queen Margaret University, Napier University, the University of Strathclyde, the University of Edinburgh and the University of Aberdeen; as well as scholars from University College London and Cardiff University. For examples of various dialects of English, please go to the sister site http://www.dynamicdialects.ac.uk

    Dynamic Dialects: an articulatory web resource for the study of accents [website]
    (University of Glasgow, 2015-04-01) Lawson, Eleanor; Stuart-Smith, Jane; Scobbie, James M.; Nakai, Satsuki; Beavan, David; Edmonds, Fiona; Edmonds, Iain; Turk, Alice; Timmins, Claire; Beck, Janet M.; Esling, John; Leplatre, Gregory; Cowen, Steve; Barras, Will; Durham, Mercedes
    Dynamic Dialects (www.dynamicdialects.ac.uk) is an accent database, containing an articulatory video-based corpus of speech samples from world-wide accents of English. Videos in this corpus contain synchronised audio, ultrasound-tongue-imaging video and video of the moving lips. We are continuing to augment this resource. Dynamic Dialects is the product of a collaboration between researchers at the University of Glasgow, Queen Margaret University Edinburgh, University College London and Napier University, Edinburgh. For modelled International Phonetic Association speech samples produced by trained phoneticians, please go to the sister site http://www.SeeingSpeech.ac.uk
