Efficient Signal Quality Improvement Approach for Wideband VoIP System in Pervasive Environment

Voice over Internet Protocol (VoIP) is a the best alternative to the traditional voice communication system, since VoIP system converges the data, voice and video data and reduces the cost of call transmission by passing packets through the available bandwidth through internet protocol. Since the environmental noise may affect the intelligibility of the speech signal, so it is desirable to use the speech processing methods to enhance the quality and intelligibility of the speech signal. The proposed scheme, Interpolated Finite Impulse Response (IFIR), is implemented as post-processor after decoding the signal in wideband VoIP system.
