Several board manufacturers have added hardware echo cancellation as an extra price option. On my side, this is perfect thought. The goal is to make an open source smart speaker for daily use. Echo Return Loss Enhancement (ERLE) Since you have access to both the near-end and far-end speech signals, you can compute the echo return loss enhancement (ERLE), which is a smoothed measure of the amount (in dB) that the echo has been attenuated.From the plot, observe that you achieved about a 35 dB ERLE at the end of the convergence period. It includes game linking, so voice from other players comes from the direction of their characters, and has echo cancellation so the sound from your loudspeakers won't be audible to other players.
