Trend detection noisy speech signal. (a) Standardized empirical mean of the fine-to-coarse EMD reconstruction, evidencing as the change point; (b) top: original signal, middle: estimated trend obtained from the partial reconstruction with IMFs 3 to 7 + the residual, bottom: noise (detrended) signal obtained from the partial reconstruction with IMFs 1 to 2.
