The wave of voice signal is narrow and unstable. Besides, it has a non-continuity in time domain and an inconsistent decline of the radio channel, especially the short wave channel, which makes estimating the time delay of the radio’s voice signal very difficult. To solve such problems, the authors creatively combine the voice activity detection with the short-segment processing technology. Meanwhile, by using Weighted Least Squares Phase Fitting method to work out the time delay, we conduct a research in the time delay estimation of radio’s voice signal. The laboratory finding finally shows that this method is far better than the typical Generalized Correlation Method for estimation of time delay.
