Concatenative data-driven synthesis methods based on a large database of sounds and a unit selection algorithm are gaining more interest in the computer music world. We briefly describe recent related work and then focus on new developments in our CATERPILLAR synthesis system: the advantages of the addition of a relational SQL database, work on segmentation by alignment, the reformulation and e...

PURPOSE The purpose of the study was to determine whether distinct subgroups of preschool children with speech sound disorders (SSD) could be identified using a subgroup discovery algorithm (SUBgroup discovery via Alternate Random Processes, or SUBARP). Of specific interest was finding evidence of a subgroup of SSD exhibiting performance consistent with atypical speech motor control. METHOD N...

We present anatomic and acoustic data from a pilot study on the Finnish vowels [A, e, i, o, u, y, æ, ø]. The data were acquired simultaneously with 3D magnetic resonance imaging (MRI) and a custom built sound recording system. The data consist of a single static repetition of each vowel with constant f0. The imaging sequence was 7.6 s long and had an isotropic voxel size of 1.8 mm. We report re...

Dynamic analyses struggle to detect all of a program’s dataraces, since some data races do not manifest in observedexecutions. Predictive analyses detect true data races thatexist only in other, unobserved executions. Smaragdakiset al. introduce the causally-precedes (CP) relation and apolynomial-time analysis for sound (no false races) predic-tive data race detection. H...

In analyzing abstract data sets, it is useful to represent them in several alternative formats, each format bringing out different aspects of the data. While most work in data mapping has focused on visual representations, we have found that sonic representations can also be effective aids in interpreting complex data, especially when sonification is used in conjunction with visualization. We h...

In order to recognise speech in a background of other sounds, human listeners must solve two perceptual problems. First, the mixture of sounds reaching the ears must be parsed to recover a description of each acoustic source, a process termed ‘auditory scene analysis’. Second, recognition of speech must be robust even when the acoustic evidence is missing due to masking by other sounds. This pa...

This paper presents a system for exploring different dimensions of a sound through the use of haptic feedback. The Novint Falcon force feedback interface is used to scan through soundfiles as a subject moves their hand horizontally from left to right, and to relay information about volume, frequency content, envelopes, or potentially any analysable parameter back to the subject through forces a...
