Method and apparatuses for improving quality of digitally encoded speech in the presence of interference

A machine-readable medium that provides executable instructions, which when executed by a processor, cause the processor to perform a method comprising:

• encoding a first portion of a signal using a first encoding technique;
• encoding a second portion of the signal using a second encoding technique;
• creating a transmission packet having a plurality of bits such that a first number of bits represent the encoded first portion of the signal and a second number of bits represent the encoded second portion of the signal.

An apparatus comprising a processor and a memory coupled thereto, the memory having stored thereon executable instructions which when executed by the processor, cause the processor to encode a first portion of an analog speech signal using a first encoding technique, encode a second portion of the analog speech signal using a second encoding technique, and create a speech transmission packet having a plurality of bits such that a first number of bits represent the encoded first portion of the analog speech signal and a second number of bits represent the encoded second portion of the analog speech signal.

An apparatus comprising a processor and a memory coupled thereto, the memory having stored thereon executable instructions which when executed by the processor, cause the processor to receive a speech transmission packet having a plurality of bits, a first number of bits representing an encoded first portion of an analog speech signal encoded using a first encoding technique, and a second number of bits representing an encoded second portion of the analog speech signal encoded using a second encoding technique, decode the first number of bits in accordance with the first encoding technique, and decode the second number of bits in accordance with the second encoding technique.

A system comprising:

• a transmitter to transmit a speech transmission packet representing an encoded speech signal, the speech transmission packet containing a plurality of bits, a first number of the plurality of bits corresponding to a first portion of the encoded speech signal and a second number of the plurality of bits corresponding to a second portion of the encoded speech signal, the first portion of the encoded speech signal encoded using a first encoding technique, and the second portion of the encoded speech signal encoded using a second encoding technique;
• and
• a receiver to receive the speech transmission packet from the transmitter and decode the first number of bits in accordance with the first encoding technique and decode the second number of bits in accordance with the second encoding technique.
