| Abstract(in English) | This paper reports the results of the preliminary experiments for interfacing sound stream segregation systems to speech understanding system. Its main issue is spectrum distortion of input sound caused by three processing of sound stream segregation-harmonic structure extraction, head transfer function (HRTF), and grouping. The experiments with a discrete single codebook HMM-LR shows that spectrum distortion caused by harmonic structure extraction is negligible. Spectrum distortion caused by HRTF and grouping are considerable large and can be overcome by re-learning of the parameters of HMM-LR by training data applied by HRTF. |
