How phonetic features project more talk

Distinctive features and phonetic dimensions

Learning phonetic features from waveforms

Unsupervised learning of broad phonetic classes by infants was simulated using a statistical mixture model. With the phonetic labels removed, hand-transcribed segments from the TIMIT database were used in model-based clustering to obtain data-driven classes. Simple Hidden Markov Models were chosen to be the components of the mixture, with Mel-Cepstral coefficients as the front-end. The sound cl...

Dynamic lexicon using phonetic features

In order to better model pronunciation variations, we present in this paper a method to build a lexicon whose content changes dynamically with the input speech. To achieve this goal, we proceeded in two steps. In the first step, a static augmented lexicon is created by adding new phone transcriptions to a basic lexicon. These new variants are derived from phonetic features that are automaticall...

Do arthritic patients talk more?

BACKGROUND The modification of speech properties in patients may indicate a more profound pathology. Ample research has been undertaken in relation to different demographic and genetic factors on arthritis but significant research on speech in arthritis had not been conducted globally. The objective of this study was to investigate the effect of arthritis on the duration of speech in patients. ...

Phonetic Detail and the Organisation of Talk-in-interaction

This paper examines some methodological and empirical issues concerning phonetic detail and phonetic variability and the work they accomplish in everyday talk-in-interaction. By considering the phonetic and sequential design of a variety of conversational practices I show that phonetic aspects of language should in the first instance be understood as shaped by interactional considerations. I ar...
