What is single channel speech enhancement?

2.3.1 Single Channel Speech Enhancement

This algorithm estimates the clean speech signal from the noisy speech signal which is available in a single channel provided by one microphone, shown in Fig. 1. Noise Reduction Process. x(n)=s(n)+d(n)

What is single channel speech?

Single channel speech separation (SCSS) is widely used in many real-time applications such as preprocessing stage for speech recognition to control humanoid robots and in hearing aid. The performance of the separation is crucial for these applications.

What are the speech enhancement techniques?

A number of speech enhancement techniques have been reported in the literature [32]. They include spectral subtraction [33, 34, 41], Wiener and Kalman filtering [35], MMSE estimation [36], comb filtering [32], subspace methods [37, 38], and phase spectrum compensation [39, 40].

What do you mean by speech enhancement?

Speech enhancement aims to improve speech quality by using various algorithms. The objective of enhancement is improvement in intelligibility and/or overall perceptual quality of degraded speech signal using audio signal processing techniques.
