SPEECH ENHANCEMENT FOR CROSS - TALKINTERFERENCEbyLevent
نویسنده
چکیده
Speech signals are often degraded by additive interference over single channel communication systems. For stationary and well deened noise sources, eeective solutions exist. However, it is often diicult to formulate a model for non-stationary and speech-like noise sources such as cross-talk or multi-speaker babble, which exist in real scenarios. In this paper, we propose a solution to this problem under the assumption that we have access to the clean speech signal prior to transmission. A novel method for tracking transmission noise characteristics is described. Based on this noise estimate , a new speech enhancement technique is proposed. The enhancement method is evaluated for multi-speaker babble noise, and shown to substantially improve both the quality and intelligibility of the processed speech signal.
