Current Public Switched Telephone Networks (PSTN) band limit, speech to 4 kHz to cater to the bandwidth limitation in their transmission medium. Narrow-band speech when compared to normal speech has a muffled characteristic, which results in reduced intelligibility. This is particularly noticeable in high frequency fricatives sounds in speech such as Id, /sh/ and /fl.
