CONDENSED SOLAR RADIATION DATA BASE
An essential part of the development of computer based solar energy system design and sizing is the acceptance of a common solar radiation data base to minimize calculation time and to facilitate comparative studies made by different organizations. The data records used in the Australian Solar Radiation Data Handbook are available in computer compatible form, […]
Two-Stage Algorithm for One-Microphone Reverberant Speech Enhancement
Under noise-free conditions, the quality of reverberant speech is dependent on two distinct perceptual components: coloration and long-term reverberation. They correspond to two physical variables: signal-to-reverberant energy ratio (SRR) and reverberation time, respectively. Inspired by this observation, we propose a two-stage reverberant speech enhancement algorithm using one microphone. In the first stage, an inverse filter […]
Single Channel Speech Dereverberation based on Spectral Subtraction
Speech signals recorded with a distant microphone usu- ally contain reverberation, which degrades the ¯delity and intelligibility of speech in devices such as ‘hands{free’ conference telephones, auto- matic speech recognition and hearing aids. One important e®ect of re- verberation on speech is overlap{masking, i.e. the energy of the previous phonemes is smeared over time, and […]
