SUMMARY In this paper, we propose an adaptive noise canceler (ANC) with speech suppressors to reduce noise in car environment, where the noise consists of directional and diffuse noise signals. Although the ANC is useful for suppressing the directional noise, its capability is degraded when a desired speech signal is observed at both microphones simultaneously. Such situation is called as crosstalk. To solve this problem, we introduce two speech suppressors into the ANC, and employ one noise suppressor as a postfilter to suppress diffuse noise. Simulation results show that the proposed method effectively suppresses both of directional noise and diffuse noise.
