Impact of speaking style and speaking task on acoustic models

The loss in performance caused by mismatch between train and test material suggests a need for task specific acoustic models, especially for highly demanding tasks. However, since the training of these models is extremely expensive, general pur­ pose models are more attractive. In this paper we address the impact of mismatch in speaking style and task. We trained three sets of acoustic models o...

Effect of Speaking Style on LVCSR Performance

SRI collected a corpus to study how spontaneous speech differs from other types of speech. The corpus was collected in two parts: (1) a spontaneous Switchboard-style conversation on an assigned topic, and (2) a reading session in which participants read transcripts of their conversation from part 1. Experiments were conducted on sentences with identical transcripts that varied in speaking style...

Perceptual compensation for differences in speaking style

It is well-established that listeners will shift their categorization of a target vowel as a function of acoustic characteristics of a preceding carrier phrase (CP). These results have been interpreted as an example of perceptual normalization for variability resulting from differences in talker anatomy. The present study examined whether listeners would normalize for acoustic variability resul...

Speaking style dependency of formant targets

Previous work on formant targets has assumed that these targets are independent of the speaking style. In this paper, we estimate consonant and vowel targets in a database of “clear” and “conversational” speech, using both style-independent and style-dependent models. The test-set errors and clustering of the estimated target values indicate that for this corpus, formant targets depend on the s...
