Low-latency smartphone app for real-time noise reduction of noisy speech signals

This papers presents a low-latency smartphone app to achieve real-time noise reduction of speech signals in noisy sound environments. This app overcomes the two shortcomings of high latency and musical noise artifact that are associated with the previously developed apps for the same purpose. The results of both objective and subjective evaluations are reported which show the effectiveness of this app towards reducing noise for speech signals in noisy environments, in particular in babble background noise.
