BACKGROUND Pharyngoesophageal spasm is a known entity to cause hypertonic/failed tracheoesophageal speech and is successfully treated by botulinum toxin A injection. However, success of botulinum toxin treatment is based on the accurate localization of the pharyngoesophageal segment. METHODS A 65-year-old man who had a laryngectomy using voice prosthesis with hypertonic speech underwent ultra...

The quantal response equilibrium (QRE) notion of McKelvey and Palfrey (1995) has recently attracted considerable attention, due in part to its widely documented ability to rationalize observed behavior in games played by experimental subjects. However, even with strong a priori restrictions on unobservables, QRE imposes no falsifiable restrictions: it can rationalize any distribution of behavio...

ATR-MATRIX is a multi-lingual speechto-speech translation system designed to facilitate communications between two parties of different languages engaged in a spontaneous conversation in a travel arrangement domain. In this paper, we propose a new evaluation method for speech translation systems. Our current focus is on measuring the robustness of a language translation sub-system, with quick c...

Speech-based training agents can be described as virtual humans posing as interactive training characters with the capability to communicate in a spoken conversational manner. While creating this technology, developers face two stumbling blocks: 1) modeling the agent and its training knowledge is a time-consuming and tedious task, and 2) modern speech recognition software suffers from high Word...

Recent empirical research has shown conclusive advantages of multimodal interaction over speech-only interaction for map-based tasks. This paper describes a mul-timodal language processing architecture which supports interfaces allowing simultaneous input from speech and gesture recognition. Integration of spoken and gestural input is driven by uniication of typed feature structures representin...

Kurzfassung: It has been shown that dialogue systems benefit from incremental architectures to produce fast responses and to interact with the interlocutor in a more human-like way. The advantage of quick responses yields the disadvantage of running out of things to say for a while. In such occasions, humans tend to produce disfluencies as a listener-oriented strategy to signal the ongoing prod...

We describe a continuous-speech interface for Quick Medical Reference (QMR), which allows physicians to input spoken descriptions of physical-examination findings, or observations. We analyze the difficulties in designing a continuous-speech interface for systems that use medical terminology. We present a method for matching spoken findings names expressed in natural language to QMR terms. The ...

We have previously proposed a fast spoken term detection method that uses a suffix array as a data structure. By applying dynamic time warping on a suffix array, we achieved very quick keyword detection from a very large-scale speech document. In this study, we modify our method so that it can deal with multiple recognition results. By using these results obtained from various speech recognizer...

In this paper we present a novel spectral distortion measure with interframe memory. The memory gives the possibility to take into account the dynamics of the time evolution of the speech spectrum, which has shown to have a significant importance on the perceived speech quality. Memory is introduced by linear filtering of the time evolution of the difference log spectrum. This facilitates smoot...
