This paper presents a method for separating speech of individual speakers from the combined speech of two speakers. The main objective of this work is to demonstrate the significance of the combined excitation source based temporal processing and short-time spectrum based spectral processing method for the separation of speech produced by individual speakers. Speech in a two speaker environment is simultaneously collected over two spatially separated microphones. The speech signals are first… CONTINUE READING

Key Quantitative Results

  • The SNR gain and MOS values show that the proposed combined temporal and spectral processing method provides an average improvement in the performance of 5.83% and 8.06% respectively, compared to the best performing individual temporal or spectral processing methods.
