Patent ID: 6889183

Claim:
A method of generating a new audio segment for an audio signal, the audio signal having a plurality of audio segments, the method comprising: receiving a stream of Internet Protocol (IP) packets, each IP packet encoding one of a plurality of segments of the audio signal; determining that a given audio segment associated with an IP packet that is missing from the stream of IP packets is not ascertainable, the location of the given audio segment within the audio signal being ascertainable; locating a set of consecutive audio segments in the audio signal, the set of consecutive audio segments decoded from IP packets in the stream immediately preceding the given audio segment and having a formant; removing the formant from the set of audio segments to produce a set of residue segments having a pitch; processing the pitch of the set of residue segments to produce a new set of residue segments; and adding the formant of the consecutive set of audio segments to the new set of residue segments to produce an output audio segment.
