    1. The Effect of Lexical Frequency on Tone Production

      ICPhS XVI ID 1164 Saarbrücken, 6-10 August 2007 THE EFFECT OF LEXICAL FREQUENCY ON TONE PRODUCTION Yuan Zhao, Dan Jurafsky Department of Linguistics, Stanford University, CA 94305, U.S.A. {yuanzhao,jurafsky}@stanford.edu ABSTRACT Previous research has identified robust effects on segmental production of lexical factors like word frequency, predictability or neighborhood density. One question that remains unanswered is whether such lexical effects hold also at the suprasegmental level. This s

    2. Method to hierarchical pooling of opinions from multiple sources

      Disclosed is a system, method, and program storage device of aggregating opinions comprising consolidating a plurality of expressed opinions on various dimensions of topics as discrete probability distributions, generating an aggregate opinion as a single point probability distribution by minimizing a sum of weighted divergences between a plurality of the discrete probability distributions, and presenting the aggregate opinion as a Bayesian network, wherein the divergences comprise Kullback-Liebler distance divergences, and wherein the expressed opinions are generated by experts and comprise opinions on sentiments of products and services. Moreover, the aggregate opinion predicts success of the products and services. Furthermore, the ...

    4. Prosodic databases holding fundamental frequency templates for use in speech synthesis

      Prosodic databases hold fundamental frequency templates for use in a speech synthesis system. Prosodic database templates may hold fundamental frequency values for syllables in a given sentence. These fundamental frequency values may be applied in synthesizing a sentence of speech. The templates are indexed by tonal pattern markings. A predicted tonal marking pattern is generated for each sentence of text that is to be synthesized, and this predicted pattern of tonal markings is used to locate a best-matching template. The templates are derived by calculating fundamental frequencies on a pursuable basis for sentences that are spoken by a human trainer ...
