We describe an experimental text-to-speech system that uses information about syntactic constituency, adjacency to a verb, and constituent length to determine prosodic phrasing for synthetic speech. A central goal of our work has been to characterize "discourse neutral" phrasing, i.e. sentence-level phrasing patterns that are independent of discourse(More)
Our goal is to use natural language processing to identify deceptive and non-deceptive passages in transcribed narratives. We begin by motivating an analysis of language-based deception that relies on specific linguistic indicators to discover deceptive statements. The indicator tags are assigned to a document using a mix of automated and manual methods.(More)
In automatic speech recognition (ASR) enabled applications for medical dictations, corpora of literal transcriptions of speech are critical for training both speaker independent and speaker adapted acoustic models. Obtaining these transcriptions is both costly and time consuming. Non-literal transcriptions, on the other hand, are easy to obtain because they(More)
While various aspects of syntactic structure have been shown to bear on the determination of phrase-level prosody, the text-to-speech field has lacked a robust working system to test the possible relations between syntax and prosody. We describe an implemented system which uses the deterministic parser Fidditch to create the input for a set of prosody(More)
This paper focuses on some characteristics of disfluencies in human-human (HHI) and human-computer (HCI) interaction corpora to outline similarities and differences. The main variables studied are disfluency rates and prosodic features. Structured, table-like input increases the disfluency rate in HCI and decreases it in HHI. Direct exposure (visibility) to(More)
In this paper, we concern ourselves with an application of text-to-speech for speech-impaired, deaf, and hard of hearing people. The application is unusual because it requires real-time synthesis of unedited, spontaneously generated conversational texts transmitted via a Telecommunications Device for the Deaf (TDD). We describe a parser that we have(More)
Of the various subdisciplines in Artificial Intelligence , only a few have matured to the state that practical application seems imminent. Of these, computational linguistics appears to be a leading contender for real world applications in the immediate future. One area of special interest to the Naval Research Laboratory (NRL) is the application of(More)
