First Claim

1. A method for communicating information in an environment that interferes with audible speech, the method comprising:
- choosing at least a first sub-audible word or phrase (SAWP) and a second SAWP to be first and second representational SAWPs (Rep-SAWPs), respectively, where each Rep-SAWP is chosen to provide optimal likelihood of recognition of the transmitted SAWP signal in an ambient environment,receiving at least one SAWP, from among the first SAWP and the second SAWP, at a wireless signaling module that processes and transmits sub-audible speech signals over a signaling channel to at least one recipient module;
determining if the at least one SAWP is a word or phrase in a SAWP lexicon associated with the module; and
when the at least one SAWP is recognized as belonging to the SAWP lexicon;
(i) transmitting the least one SAWP representing the received SAWP over the signaling channel; and
(ii) receiving the at least one SAWP from the signaling channel at the recipient module and converting the received at least one SAWP to at least one of visually perceptible alphanumeric text, audibly perceptible speech, and a coded signal representing the SAWP.

Abstract
Method and system for generating electromyographic or sub-audible signals (“SAWPs”) and for transmitting and recognizing the SAWPs that represent the original words and/or phrases. The SAWPs may be generated in an environment that interferes excessively with normal speech or that requires stealth communications, and may be transmitted using encoded, enciphered or otherwise transformed signals that are less subject to signal distortion or degradation in the ambient environment.

24. A system for communicating information in an environment that interferes with audible speech, the system comprising:
-
a receiver-evaluator for receiving at least one of a first sub-audible word or phrase (SAWP) and a second SAWP and for determining if the SAWP is a word or phrase in a SAWP lexicon associated with the evaluator; and a transmitter for transmitting a SAWP representing at least one of the first and second received SAWPs over a signaling channel to at least one recipient, when the received SAWP is determined to be contained in the SAWP lexicon, wherein the SAWPs associated with first and second received SAWPs are respective first and second representational SAWPs (Rep-SAWPs) that are chosen to provide optimal likelihood of recognition of the transmitted SAWPs in an ambient environment. - View Dependent Claims (25, 26, 27)
