Abstract :
A background noise suppression system used for preprocessing a speech codec for private mobile radio is described. The system is able to suppress the sounds of fire engine sirens and other background noises. Employing the system enabled the sound articulation of synthetic speech to be improved more than 5% at a signal-to-noise ratio of 5 dB
