To adopt a constructional approach is to undertake a commitment in principle to account for the entirety of each language. This means that the relatively general patterns of the language, such as the one licensing the ordering of a finite auxiliary verb before its subject in English as illustrated in (1), and the more idiomatic patterns, such as those(More)
1Above all, I’d like to thank Paul Kay for hours of discussion and useful feedback at every stage in the seemingly endless process of writing this chapter. I’m also grateful to Chuck Fillmore and Laura Michaelis for many useful discussions of both content and exposition and for comments on an earlier draft, which was also been improved by the comments of(More)
To date, studies of deceptive speech have largely been confined to descriptive studies and observations from subjects, researchers, or practitioners, with few empirical studies of the specific lexical or acoustic/prosodic features which may characterize deceptive speech. We present results from a study seeking to distinguish deceptive from non-deceptive(More)
This paper describes a prototype system for near-real-time spontaneous, bidirectional translation between spoken English and Pashto, a language presenting many technological challenges because of its lack of resources, including both data and expert knowledge. Development of the prototype is ongoing, and we propose to demonstrate a fully functional version(More)
Reverberation in speech degrades the performance of speech recognition systems, leading to higher word error rates. Human listeners can often ignore reverberation, indicating that the auditory system somehow compensates for reverberation degradations. In this work, we present robust acoustic features motivated by the knowledge gained from human speech(More)
We summarize recent progress on SRI's IraqComm™ Iraqi Arabic-English two-way speech-to-speech translation system. In the past year we made substantial developments in our speech recognition and machine translation technology, leading to significant improvements in both accuracy and speed of the IraqComm system. On the 2008 NIST-evaluation dataset our(More)
We study the question of how intrinsic variations (associated with the speaker rather than the recording environment) affect text-independent speaker verification performance. Experiments using the SRI-FRTIV corpus, which systematically varies both vocal effort and speaking style, reveal that (1) “furtive” speech poses a significant challenge; (2)(More)
