SYSTEM AND METHOD FOR METHOD FOR IMPROVING SPEECH INTELLIGIBILITY OF VOICE CALLS USING COMMON SPEECH CODECS
First Claim
1. A method to improve intelligibility of coded speech, comprising:
- receiving an encoded speech signal from a network;
extracting an encoded media data stream and one or more control data packets from the encoded speech signal;
decoding the encoded media data stream to produce a decoded speech signal;
boosting an upper spectral portion of the decoded speech signal to produce a boosted speech signal; and
outputting the boosted speech signal.

Abstract
System and method to improve intelligibility of coded speech, the method including: receiving an encoded speech signal from a network; extracting an encoded media data stream and one or more control data packets from the encoded speech signal; decoding the encoded media data stream to produce a decoded speech signal; boosting an upper spectral portion of the decoded speech signal to produce a boosted speech signal; and outputting the boosted speech signal. In another embodiment, the method may include: receiving an uncoded speech signal; processing the uncoded speech signal, wherein the processing comprises generating an unencoded data stream from the uncoded speech signal; boosting an upper spectral portion of the unencoded data stream to produce a boosted speech signal; encoding the boosted speech signal to produce an encoded speech signal; and outputting the boosted speech signal.
