In this paper, we consider articulatory processes in a connectionist model of reading aloud to account for effects of manner of articulation of the initial segment in a variety of tasks. We first describe experimental results showing how flexibility in articulation can completely eliminate the a priori acoustic latency difference between plosives and non-plosives in some tasks, and exaggerate t...

We propose an e ective application of speech recognition to foreign language pronunciation learning. The objective of our system is to detect pronunciation errors and provide diagnostic feedback through speech processing and recognition methods. Automatic pronunciation error detection is used for two kinds of mispronunciation, that is mistake and linguistical inheritance. The correlation betwee...

The present study examines the temporal and spectral characteristics of Greek fricatives (duration and spectral moments, i.e. mean, variance, skewness, kurtosis) as distinctive cues for their place of articulation. The effects of voicing, speaker’s gender and post-fricative vowel on both duration and spectral moments are also investigated. The results indicate that noise duration does not disti...

In this paper we present our exploration of co-designing for supporting a collaborative articulation of rehabilitation process. Based on our reading of key CSCW literature, we describe three facets of a collaboratively articulated rehab process: Interdependence, Distributed Process, and Interoperability. We highlight Magic-MirrorSpiral, the design ideal guiding the co-designing of MyReDiary tha...

The issue of whether young children rehearse in auditory memory tasks was investigated across a series of three studies comparing individual differences in articulation rates and memory spans. Applying the principles of the working-memory model, children with faster rates of speaking should have superior memory spans if they engage in rehearsal. Two of the experiments, with 4-year-old children,...

We define as an ’articulation point’ in a lattice an element which is comparable to all the other elements, but is not extremum. We investigate a property which holds for both the lattice of a binary relation and for the lattice of the complement relation (which we call the mirror relation): one has an articulation point if and only if the other has one also. We give efficient algorithms to gen...

We investigated the speech recognition of a person with articulation disorders resulting from athetoid cerebral palsy. Recently, the accuracy of speaker-independent speech recognition has been remarkably improved by the use of stochastic modeling of speech. However, the use of those acoustic models causes degradation of speech recognition for a person with different speech styles (e.g., articul...

Philosophy invariably starts with the attempt to spell out ideas and beliefs that we already hold, whether on topics like time or causality, colour or value, consciousness or free will, democracy or justice or freedom. It may go well beyond such pre-philosophical assumptions in its further developments, regimenting them in unexpected ways, revising them on novel lines, even discarding them enti...

In this paper, a study on articulation rate variation within the prosodic phrase is presented. The dialect under investigation is south Swedish. South Swedish shares many prosodic properties with Danish, a language claimed to lack phrasefinal lengthening. The results of the present study nevertheless indicate that the articulation rate in south Swedish phrases is significantly lower in phrase-f...

Many potential applications of virtual agents require an agent to conduct multiple conversations with users. An effective and engaging agent should modify its behavior in realistic ways over these conversations. To model these changes, we gathered a longitudinal video corpus of humanhuman counseling conversations, and constructed a model of changes in articulation rates over multiple conversati...
