概要 Introducing the dereverberation process to the hearing aid device is considered to be effective. In recent research, dereverberation techniques have been divided into the following three classes: beamforming method, blind deconvolution method and speech enhancement method. In our previous research, an SS-based dereverberation method with the blind estimation of reverberation energy was proposed. We use only single-channel speech signals based on exponential averaging with attack and release time constants. In this research, the previously-proposed method was implemented on a prototype of an electronic board for hearing aid device, including the parameter settings. The system latency is about 8 ms. The parameter is set optimally according to the previously mentioned results. In addition, a listening experiment was also conducted using the prototype board to evaluate the system under the actual environment which has long reverberation.
