Speech Enhancement Based on Hilbert-Huang Transform Theory


Speech enhancement is effective in solving the problem of noisy speech. Hilbert-Huang transform (HHT) is efficient for describing the local features of dynamic signals and is a new and powerful theory for the time-frequency analysis. According to the theory of HHT, this text introduced a new method of speech enhancement to improve the speech quantity and… (More)
