Evaluation of microphone arrays for enhancing noisy and reverberant speech for coding
Z. Li, Marci Hoffman · IEEE Transactions on Speech and Audio Processing · 1999
A robustly constrained minimum variance adaptive array algorithm for general noise suppression and subsequent speech coding is applied in realistic room environments. The results indicate that the robust algorithm is suitable for enhancing speech for subsequent coding. Results also show that the array processing gains are transparent to a CELP coder but not necessarily to an LPC-10 coder.
