Voice Activity Detection in Noisy Environments Based on Double-Combined Fourier Transform and Line Fitting
Figure 11
Results of the proposed algorithm in the environment of high speed driving on highway: (a) noisy speech signal at SNR −8 dB, (b) speech obtained manually by applying noise reduction [19] to (a) signal, (c) the proposed feature, and (d) edge detection filter output based on the proposed feature.
