Details | A speech enhancement technology for auditory barrier-free between elderly and younger persons was introduced. In the first study, an acoustic feature associated with the auditory impression was investigated. Then, the enhancement technology based on the feature was proposed and evaluated. The results suggested that the proposed technology was effective to improve the auditory impression. Furthermore, speech analysis methods for atypical speech such as shout and hoarse speech and noise suppression methods for noisy speech were also proposed. Evaluations for these methods were carried out, and their effectiveness was demonstrated. |
