We present a novel graphical user interface (GUI) that facilitates high-efficacy collection of perceptual similarity opinions of a user in an effective and intuitive manner. The GUI is based on a hybrid mechanism that combines ranking and rating. Namely, it presents a base image for rating its similarity to seven peripheral images that are simultaneously displayed in a circular layout. The user...

This paper presents an empirical method for assessing music similarity on a set of stimuli using triadic comparisons in a balanced incomplete block design. We first evaluated the consistency of subjects in their rankings and then the concordance across subjects. The concordance was also evaluated for different subject populations to assess the influence of experience of the subject with the mus...

This paper reports the results of two experiments aimed at assessing the perceived similarity between a set of English and Catalan vowels from the perspective of native speakers of both languages. Two groups of 27 listeners, a group of native English speakers and a group of native Catalan speakers, used a 9-point scale to rate the degree of similarity between two stimuli. Crucial stimuli consis...

For almost a decade, Content-Based Information Retrieval has been an active research area, yet two fundamental problems remain largely unsolved: how best to learn users’ query concepts, and how to measure perceptual similarity. To learn subjective query concepts, most systems use relevance feedback techniques. However, these traditional techniques often require a large number of training instan...

Texture classification and segmentation have been extensively researched over the last thirty years. Early on the Brodatz album[1] quickly became the de facto standard in which a texture class comprised a set of nonoverlapping sub-images cropped from a single photograph. Later, as the focus shifted to investigating illuminationand pose-invariant algorithms, the CUReT database[3] became popular ...

Both phonological and morphological reasons have been suggested to account for mismatched elements in reduplicative outputs (e.g. gbóná is reduplicated as gbí-gbóná in Yoruba). However, the mismatched tonal sequences in Cantonese vocative reduplication are not amenable to either account (namely, the Emergence of the Unmarked account and the Morphological Doubling Theory account). This study pro...

This paper extends a study on music similarity perception presented at ISMIR last year, in which subjects ranked the similarity of excerpt-pairs presented in triads [1]. The larger number of subjects and stimuli in the current study required a modification of the methodological strategy. We use here two nested incomplete block designs in order to cover the full set of song-excerpts comparisons ...

This paper describes the correlations between various acoustic features and perceptual voice quality similarity. We focus on identifying the acoustic features that are correlated with voice quality similarity. First, a large-scale perceptual experiment using the voices of 62 speakers is conducted and perceptual similarity scores between each pair of speakers are acquired. Next, multiple linear ...
