Resonator-based creaky voice detection
Thomas Drugman, John Kane, Christer Gobl · 2012
Creaky voice is used by speakers for a variety of interactive, expressive and stylistic reasons. As a result the accurate detection of creaky regions in speech can yield important information not captured within the propositional content of spoken utterances. Hence, we describe a new method for automatically detecting creaky regions following the observation that secondary peaks occur in the linear prediction residual signal. The proposed approach was shown to significantly outperform the state-of-theart in an objective evaluation on a range of speech databases.
