Abstract :
Spectral cues are important for speech intelligibility, but they are distorted, in most popular multi-band compression algorithms for hearing aids, by being split into multiple bands and processed by different amplifiers. The paper presents a morphology-based method, which can preserve primary spectral cues and have low computation cost. Speech testing results demonstrate its efficiency.
