      A major challenge in the field of automatic recognition of emotion and affect in speech is the subjective nature of affect labels. The most common approach to acquiring affect labels is to ask a panel of listeners to rate ...
    • Identifying Uncertain Words within an Utterance via Prosodic Features 

      Pon-Barry, Heather Roberta; Shieber, Stuart M. (International Speech Communication Association, 2009)
      We describe an experiment that investigates whether sub-utterance prosodic features can be used to detect uncertainty at the wordlevel. That is, given an utterance that is classified as uncertain, we want to determine which ...
    • The Importance of Sub-Utterance Prosody in Predicting Level of Certainty 

      Pon-Barry, Heather Roberta; Shieber, Stuart M. (Association for Computational Linguistics, 2009)
      We present an experiment aimed at understanding how to optimally use acoustic and prosodic information to predict a speaker's level of certainty. With a corpus of utterances where we can isolate a single word or phrase ...
    • Inferring Speaker Affect in Spoken Natural Language Communication 

      Pon-Barry, Heather Roberta (2013-03-15)
      The field of spoken language processing is concerned with creating computer programs that can understand human speech and produce human-like speech. Regarding the problem of understanding human speech, there is currently ...

      Pon-Barry, Heather Roberta; Shieber, Stuart M. (Hindawi Publishing Corporation, 2011)
      We address the problem of inferring a speaker’s level of certainty based on prosodic information in the speech signal, which has application in speech-based dialogue systems. We show that using phrase-level prosodic features ...
