INTERSPEECH 2006 Personality Factors in Human Deception Detection: Comparing Human to Machine Performance (2008)

Frank Enos, Stefan Benus, Robin L. Cautin, Martin Graciarena, Julia Hirschberg, Elizabeth Shriberg

Previous studies of human performance in deception detection have found that humans generally are quite poor at this task, comparing unfavorably even to the performance of automated procedures....

Detecting Deception Using Critical Segments (2008)

Frank Enos, Elizabeth Shriberg, Martin Graciarena, Julia Hirschberg, Andreas Stolcke

We present an investigation of segments that map to GLOBAL LIES, that is, the intent to deceive with respect to salient topics of the discourse. We propose that identifying the truth or falsity of...

Combining prosodic, lexical and cepstral systems for deceptive speech detection (2006)

Martin Graciarena, Elizabeth Shriberg, Andreas Stolcke, Frank Enos, Julia Hirschberg, Sachin Kajarekar

We report on machine learning experiments to distinguish deceptive from nondeceptive speech in the Columbia-SRI-Colorado (CSC) corpus. Specifically, we propose a system combination approach using...

Distinguishing Deceptive from Non-Deceptive Speech (2005)

Julia Hirschberg, Stefan Benus, Jason M. Brenier, Frank Enos, Sarah Friedman, Sarah Gilman, ...

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...

Progress on mandarin conversational telephone speech recognition (2004)

Mei-yuh Hwang, Xin Lei, Tim Ng, Ivan Bulyko, Mari Ostendorf, Andreas Stolcke, ...

Over the past decade, there has been good progress on English conversational telephone speech (CTS) recognition, built on the Switchboard and Fisher corpora. In this paper, we present our efforts on...

Progress in Meeting Recognition: The ICSI-SRI-UW Spring 2004 Evaluation System (2004)

Andreas Stolcke, Chuck Wooters, Nikki Mirghafori, Tuomo Pirinen, Ivan Bulyko, Dave Gelbart, ...

We describe the ICSI-SRI-UW team's entry in the Spring 2004 NIST Meeting Recognition Evaluation. The system was derived from SRI's 5xRT Conversational Telephone Speech (CTS) recognizer by...

Voicing feature integration in SRI’s Decipher LVCSR system (2004)

Martin Graciarena, Horacio Franco, Jing Zheng, Dimitra Vergyri, Andreas Stolcke

We augment the Mel cepstral (MFCC) feature representation with voicing features from an independent front end. The voicing feature front end parameters are optimized for recognition accuracy. The...

Rede neural para reconhecimento adaptativo de fonemas ruidosos (1998)
