The goal of this paper is to introduce, by means of the detailed analysis of a single grammatical problem, the rudiments of a grammatical theory which assigns a central role to the notion of grammatical construction. To adopt a constructional approach is to undertake a commitment in principle to account for the entirety of each language. 2 This means that(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 thesis describes a proposal for the treatment of derivation as part of a lexical component for HPSG. The system is not based on a `syntax of words', but solely on a hierarchical structure of the lexicon. The approach is motivated by a detailed study of bar-adjectives in German. The analysis of data from corpora has shown that a word-syntax alone is not(More)
English 'dative-movement' or 'ditransitive' phenomena are examined within both a non-monotonic approach to Construction Grammar (CG) influenced by Cognitive Linguistics and a monotonic CG approach. It is argued that the latter gives better empirical coverage and is theoretically simpler. Also an account of the argument/adjunct distinction is developed(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)
One of the recent tasks for machine translation research has been development of translation capabilities in a time frame as short as 100 days. Such a task requires developers to consider what can be done with relatively small amounts of data in a small time frame. This inherently limits the type and complexity of the effort to be devoted to this task. In(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)
Though depression is a common mental health problem with significant impact on human society, it often goes undetected. We explore a diverse set of features based only on spoken audio to understand which features correlate with self-reported depression scores according to the Beck depression rating scale. These features, many of which are novel for this(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)
