چکیده

In this paper we describe the rapid prototyping of an adaptive speech beamformer, using the Graphical Rapid Prototyping Environment: GRAPE-II [1]. We used a general purpose, commercially available multi-processor with 4 TMS320C40 DSP-processors. Our work proves the feasibility of real-time prototyping using a multiprocessor and a powerful programming

Speech enhancement and recognition by integrating adaptive beamforming and wiener filtering

A robust adaptive beamforming method is presented in this paper for speech enhancement and speech recognition with microphone arrays. The proposal is based on a modification of the Generalized Sidelobe Canceller with adaptive blocking matrix and the use of a Wiener filter. Alternatively to most of the previous reported works based on microphone arrays with postfiltering, the new technique integ...
