Table 1 The ERLE achieved by the proposed echo cancelation solution in four truck models while the engine is off
From: An acoustic echo canceller optimized for hands-free speech telecommunication in large vehicle cabins
Truck model | ERLE | WER during DT (before and after AEC) | Total code execution time (MATLAB) | Average processing time per buffer (DSP) |
|---|---|---|---|---|
FM 928 | 25.54 dB | 0.28 → 0.08 | 9.6 s | 20.3 ms |
FM 930 | 25.43 dB | 0.46 → 0.1 | 9.7 s | 20.4 ms |
FH 2099 | 27.26 dB | 0.4 → 0.08 | 10.7 s | 25.5 ms |
FH 2250 | 30.9 dB | 0.5 → 0.1 | 10.1 s | 25.2 ms |
