Figure 13From: Real-time spectrum estimation–based dual-channel speech-enhancement algorithm for cochlear implant Speech enhancement results for different lengths of the ambient-noise before the desired speech segment. (a-1), (a-2), (a-3) and (a-4) are the situations of 1 s, 450 ms, 300 ms and 200 ms lengths of the noise-only interval before the speech segment respectively, and the corresponding speech-enhancement results are shown in (b-1), (b-2), (b-3) and (b-4).Back to article page
