Subjective Quality Estimation Using PESQ For Hands-Free Terminals

Sachiko Kurihara, Masahiro Fukui, Suehiro Shimauchi, Noboru Harada

ICASSP 2020accepted

Previous reports have mentioned the possibility that subjective quality of the echo-suppressed speech signal can be estimated based on perceptual evaluation of speech quality (PESQ), but there are few experimental results. We propose third-party listening and conversational test procedures to assess…

On relationships between amplitude and phase of short-time Fourier transform

Suehiro Shimauchi, Shinya Kudo, Yuma Koizumi, Ken'ichi Furuya

ICASSP 2017accepted

The relationships between the amplitude and phase of the short-time Fourier transform (STFT) are investigated. By choosing the Gaussian window for the STFT, we reveal that the group delay and instantaneous frequency of each signal segment, both of which are derived from the phase by definition, can…
