Abstract
Methods and systems for communicating data on a cellular telephone voice channel are disclosed. The method includes segmenting a data stream into one or more n-bit symbols; identifying a human vocal sound corresponding to each n-bit symbol according to a predetermined assignment of each n-bit symbol to a human vocal sound; and retrieving data representing the human vocal sound, wherein data representing the human vocal sound is configured to be passed through a vocoder.

A method for communicating data on a cellular telephone voice channel, comprising:
- segmenting a data stream into one or more n-bit symbols;
- identifying a human vocal sound corresponding to each n-bit symbol according to a predetermined assignment of each n-bit symbol to a human vocal sound;
- and
- retrieving data representing the human vocal sound,
- wherein data representing the human vocal sound is configured to be passed through a vocoder.
A method for communicating data on a cellular telephone voice channel, comprising:
- decoding, from a cellular telephone voice signal, data representing one or more human vocal sounds, wherein each of the one or more human vocal sounds corresponds to an n-bit symbol according to a predetermined assignment of each n-bit symbol to each human vocal sound, wherein the data representing the human vocal sound is configured to be passed through a voice decoder;
- and
- identifying each n-bit symbol corresponding to each human vocal sound.
An apparatus, comprising:
- an in-band modem configured to segment a data stream into one or more n-bit symbols;
- and
- a data store operably coupled to the in-band modem, the data store configured to store a predetermined assignment of each of the one or more n-bit symbols to a human vocal sound,
- wherein data representing the human vocal sound is configured to be passed through at least one of a vocoder and a voice decoder.
A system comprising:
- a processor;
- a memory coupled to the processor;
- an in-band modem coupled to the processor and configured to segment a data stream into one or more n-bit symbols;
- and
- a data store coupled to the in-band modem, the data store configured to store a predetermined assignment of the n-bit symbol to a human vocal sound,
- wherein the human vocal sound is configured to be passed through at least one of a vocoder and a voice decoder.
