From this, a subset of the customer orders is selected as a test set. An architecture is presented which allows filled pauses and repairs to be detected and corrected. A language repair module removes fillers and reparanda and transforms utterances containing them into fluent utterances. An experiment on filled pauses using this module and architecture is then described. A speech recognition grammar for recognising fluent speech is used to provide a baseline. This grammar is then enriched with filled pauses, based on their placement in relation to syntactic boundaries. Evaluation is done at the level of understanding, using a metric on feature structures. Initial results indicate that incorporating filled pauses at syntactic boundaries improves the recognitio...

The three dimensions proposed are arousal, pleasure and power. This paper reports the findings of a perception study where 31 normally-hearing subjects rated utterances said in the emotion of happiness, sadness, two forms of anger (hot and cold) and a neutral state on the dimensional scales of arousal, pleasure and power. Findings show that the concept of the dimensions of emotion is useful to describe and distinguish emotions; and that emotions with a similar level of arousal, and sometimes a similar level of power, share acoustic characteristics in terms of F0 range and mean, and particula rly intensity mean. It is suggested that this contributes to perceived similarity between emotions, and consequently confusions, especially in the hearing-impaired.
