Abstract: In this paper, a novel method based on the phase of noisy speech and noise signals is proposed. Phase ratio based two gain functions (G1 and G2) are developed and used for correction in noisy phase to suppress noises coming from angles 0 to ±π/2 and π/2 to ±π, respectively. For the reconstruction, both gains G1 and G2 were multiplied and lower values of the phases were neglected, which gives enhancement in speech. Objective speech intelligibility measures, informal subjective listening tests and spectrogram analysis were used for finding the effectiveness of the proposed method. © 2017 IEEE.
