Abstract
A method of detecting an occurrence of splicing in a speech signal includes comparing one or more discontinuities in the test speech signal to one or more reference speech signals corresponding to the test speech signal. The method may further include calculating a frame-based spectral-like representation Sof the speech signal, and calculating a frame-based spectral-like representation Sof a reference speech signal corresponding to the speech signal. The method further includes aligning Sand Sin time and frequency, calculating a distance function associated with aligned Sand S, and evaluating the distance function to determine a score. The method also includes comparing the score to a threshold to detect if splicing occurs in the speech signal.
