“…In addition, the spatial nature of the task lends itself well to experiments designed to obtain more direct distance or spatial location measures. For example, the task could be modified to require participants to organize stimulus materials along a single dimension to obtain results similar to those in a magnitude estimation task (Granqvist, 2003). With respect to regional dialect variation, participants could be asked to indicate relative distance in a single dimension from General American English or relative position on a north-south axis to confirm …”

The free classification paradigm and its potential application to perceptual acoustic and auditory research are summarized. Specific methods for the application of the auditory free classification paradigm in speech research are then described, including techniques for stimulus preparation, data collection, and statistical analysis, based on a sample auditory free classification study of regional dialect variation. The results suggest that auditory free classification is a promising paradigm for examining the perceptual classification and similarity of speech and nonspeech auditory stimulus materials.

Purpose: Given the potential significance of speech naturalness to functional and social rehabilitation outcomes, the objective of this study was to examine the effect of listener perceptions of monopitch on speech naturalness and intelligibility in individuals with Parkinson's disease (PD). Method: Two short utterances were extracted from monologue samples of 16 speakers with PD and 5 age-matched adults without PD. Sixteen listeners evaluated these stimuli for monopitch, speech naturalness and intelligibility using the visual sort and rate method.Results: Naïve listeners can reliably judge monopitch, speech naturalness, and intelligibility with minimal familiarization. While monopitch and speech intelligibility were only moderately correlated, monopitch and speech naturalness were highly correlated. Conclusions: A great deal of attention is currently being paid to improvement of vocal loudness and thus speech intelligibility in PD. Our findings suggest that prosodic characteristics such as monopitch should be explored as adjuncts to this treatment of dysarthria in PD. Development of such prosodic treatments may enhance speech naturalness and thus improve quality of life.

“…In both cases, stimuli were blocked according to voice "families," each consisting of an original voice sample, the AbS synthesized voice, and the five synthetic tokens created with the model-fitted sources. Listeners assessed the similarity of the different family members in a visual sort-and-rate task (Granqvist, 2003;Esposito, 2010;Chen et al, 2013a;Zhang et al, 2013). In this task, each family was presented in a separate trial; each listener completed 10 trials, such that across trials and subjects each family was judged by 12 listeners.…”

Models of the voice source differ in their fits to natural voices, but it is unclear which differences in fit are perceptually salient. This study examined the relationship between the fit of five voice source models to 40 natural voices, and the degree of perceptual match among stimuli synthesized with each of the modeled sources. Listeners completed a visual sort-and-rate task to compare versions of each voice created with the different source models, and the results were analyzed using multidimensional scaling. Neither fits to pulse shapes nor fits to landmark points on the pulses predicted observed differences in quality. Further, the source models fit the opening phase of the glottal pulses better than they fit the closing phase, but at the same time similarity in quality was better predicted by the timing and amplitude of the negative peak of the flow derivative (part of the closing phase) than by the timing and/or amplitude of peak glottal opening. Results indicate that simply knowing how (or how well) a particular source model fits or does not fit a target source pulse in the time domain provides little insight into what aspects of the voice source are important to listeners.
