New blends of Speech Powered Interactive Voice Response (SEIVR) Systems have replaced the traditional time-consuming menu-driven IVRs. However, when broadcast across telecom networks using narrowband codecs, the voice signal’s quality and intelligibility degrade dramatically. Only a revolutionary technology of Artificial Band Width Extension may provide wideband quality signal without considerable alteration of the existing network infrastructure (ABWE). In this paper, ABWE is implemented with a QMF filter bank that band splits input speech into LF and HF components before compressing … Continue reading “Performance Improvement in Speech Enabled IVR Systems Using Artificial Band Width Extension: Recent Development”
