In this paper, a method for generating broadband speech from band-limited speech using spectral linear mapping is proposed. This method is based on LPC analysis and synthesis. It first extracts sound source information (residual waveforms) and vocal

Spectral band replication (SBR) is the bandwidth extension technology for the MPEG-4 audio extension 1 standard. Its principle is based on mapping the low-frequency portion of an audio signal coded at low bitrate to the missing high-frequency region,

On the analog telephone and the mobile telephone system, the bandwidth of the speech is limited from 300 Hz to 3.4 kHz. This paper proposes a new recovery method of wideband speech (50 Hz–7.4 kHz) from narrow‐band speech based on piecewise linear
