An Artificial Talker Driven from a Phonetic Input

Talker-specific influences on phonetic category structurea)

A primary goal for models of speech perception is to describe how listeners achieve reliable comprehension given a lack of invariance between the acoustic signal and individual speech sounds. For example, individual talkers differ in how they implement phonetic properties of speech. Research suggests that listeners attain perceptual constancy by processing acoustic variation categorically while...

Phonetic richness can outweigh prosodically-driven phonological knowledge when learning words in an artificial language

How do Dutch and Korean listeners use acoustic–phonetic information when learning words in an artificial language? Dutch has a voiceless ‘unaspirated’ stop, produced with shortened Voice Onset Time (VOT) in prosodic strengthening environments (e.g., in domain-initial position and under prominence), enhancing the feature { spread glottis}; Korean has a voiceless ‘aspirated’ stop produced with le...

The effects of talker variability on phonetic accommodation

This paper compares spontaneous phonetic accommodation in high and low variability talker conditions. If multi-talker processing is a kind of increased cognitive load, we predict an increase in imitation in the low variability contexts. Our results suggest that, indeed, phonetic accommodation is greater in low variability contexts, but that this higher level of accommodation is moderated as per...

Acoustic-phonetic correlates of talker intelligibility for adults and children.

This study investigated acoustic-phonetic correlates of intelligibility for adult and child talkers, and whether the relative intelligibility of different talkers was dependent on listener characteristics. In experiment 1, word intelligibility was measured for 45 talkers (18 women, 15 men, 6 boys, 6 girls) from a homogeneous accent group. The material consisted of 124 words familiar to 7-year-o...
