Investigating the emotional content in speech from acoustic characteristics requires separating the semantic content from the acoustic channel. For natural emotional speech, a widely used method to separate the two channels is the use of cue masking. Our objective is to investigate the use of cue masking in non-acted emotional speech by analyzing the extent to which filtering impacts the perception...
In this paper, we proposed a novel approach to combine sub-bands SNR for Voice Activity Detection. In the proposed algorithm, a nonlinear method based on cochlear model is used to divide sub-bands. In each sub-band, two Order Statistic Filters are used to estimate the signal SNR. Through the use of the above methods, the sub-bands SNR is combined by a linear dicriminant function calculated under the...
Speech is one of God's gifts to humans. Speech is the main way of communication. But unfortunately the dumb people are deprived of this gift. They are unable to express themselves through the act of speaking. “Virtual Voice” helps the dumb people to overcome this difficulty and speak as the normal people do. This device makes use of AG-500 Articulograph sensor which is fixed over the lips of the user...
The Multi-pulse Maximum Likelihood Quantization (MP-MLQ) algorithm with high complexity and high quality in its analysis-by-synthesis optimization has been used by many speech coding standards. To reduce the computational complexity of MP-MLQ in ITU-T G.723.1 speech codec, in this paper, we propose a fast search algorithm by using a designed function and the multi-track positions structure to predict...
