الملخص

In a number of speech applications, such as coding, synthesis or recognition, it is crucial to
make a reliable discrimination between voiced/unvoiced segments and accurately determine
the pitch period. The problem of an accurate estimation and decision in noisy condition
remains open; Higher-order statistics (H.O.S) have inherent properties that make them well
suited when dealing with a mixture of Gaussian and non-Gaussian processes.
This paper explores the fourth order cumulant using autoregressive model (AR(p)) and
presents a new algorithm for pitch detection of voiced sounds with and without colored
Gaussian noise and shows the superiority of the novel method over the classical methods such
as cepstral method.
