A novel transform-domain speech bandwidth extension algorithm is proposed to transmit information about the missing speech frequencies over a hidden channel, i.e., the related encoded spectral envelope parameters are hidden within the narrowband spee

The present public switched telephone network (PSTN) transmits signals in a frequency range of 300-3400 Hz. But wideband speech lies in the region of 50-7000Hz where we are losing some information that falls under 3400-7000Hz, so we need to find a wa

Modern packet-switched networks are increasingly capable of offering high-quality voice services such as Voice over LTE (VoLTE) which have the potential to surpass the Public Switched Telephone Network (PSTN) in terms of quality. To ensure this devel
