Diagnostic tests of segmental duration models

Conditional Moment Tests for Parametric Duration Models

This paper develops and compares specification tests for parametric duration models estimated with censored data. The tests are based on generalized residuals (the integrated hazard), which is exponentially distributed if the model is correctly specified. I present several conditional moment tests based on the generalized residuals: a raw moments test, a test based on Laguerre polynomials, and ...

Assessing the Validity of Diagnostic Tests

Quantitative Modeling of Segmental Duration

In natural speech, durations of phonetic segments are strongly dependent on contextual factors. Quantitative descriptions of these contextual effects have appfications in text-to-speech synthesis and in automatic speech recognition. In this paper, we describe a speakerdependent system for predicting segmental duration from text, with emphasis on the statistical methods used for its construction...

Segmental duration modeling in Turkish

Naturalness of synthetic speech highly depends on appropriate modeling of prosodic aspects. Mostly, three prosody components are modeled: segmental duration, pitch contour and intensity. In this study, we present our work on modeling segmental duration in Turkish using machinelearning algorithms, especially Classification and Regression Trees (CART). The models predict phone durations based on ...
