Algorithms for Near-End Listening Enhancement (NELE) improve the intelligibility of speech from the far-end, played back in a near-end noisy environment, by adaptively filtering the speech signal and taking into account the near-end background noise characteristics. In contrast to previous works, th…
In announcement and communication systems, clean speech is often played back by loudspeakers in the presence of local background noise which decreases intelligibility. Speech reinforcement is a technique that enhances the intelligibility by adaptively filtering the speech, usually based on measured…
A novel noise-robust soft Voice Activity Detector (VAD) operating in the short-time Fourier domain is presented. A speech energy gain is obtained by frame-wise processing of a noisy speech signal with a speech codebook algorithm. This gain can be used for robust voice detection. A speaker-independen…
