A wideband signal creates challenges, as it has a significant amount of consonant energy in addition to vowel sounds. Consonants are low in intensity when compared to the voiced low frequency content of the signal and have a noise-like structure, making them prone to noise distortions. The increased susceptibility of wideband systems for noise distortions need careful development of noise reduction algorithms for wideband. Algorithm developers need to modify the existing noise reduction algorithms for wideband applications or account for structural differences between narrowband and wideband signals and device different algorithmic strategy for wideband signals. They need to take these measures to develop algorithms for wideband systems. ER -
