The Ideal Ratio Mask (IRM) has proven to be very effective tool in many applications such as speech segregation, speech enhancement for hearing aid design and noise robust speech recognition tasks. The IRM provides information regarding the amount of signal power at each Time-Frequency (T-F) unit in a given signal-plus-noise mixture. In this paper, we propose to use the IRM for non-intrusive quality...
In this paper, we propose to use modified Gammatone filterbank with Teager Energy Operator (TEO) for environmental sound classification (ESC) task. TEO can track energy as a function of both amplitude and frequency of an audio signal. TEO is better for capturing energy variations in the signal that is produced by a real physical system, such as, environmental sounds that contain amplitude and frequency...
To emulate the human perception in quality assessment, an objective metric or assessment method is required, which is a challenging task. Moreover, assessing the quality of speech without any reference or the ground truth is altogether more difficult. In this paper, we propose a new non-intrusive speech quality assessment metric for objective evaluation of speech quality. The originality of proposed...
