Abstract

Voice recognition is used to turn voice to text so that just the text and a digital voice characteristic (DVC) of the voice can be transmitted by a radio. The receiving radio would combine the text and the DVC to recreate the audio. The most frequent users of the system would not send their DVC on the air. They would send a DVC identifier on the air instead of sending the DVC to save bandwidth. The most frequent users of the system would store in their radios all of the DVCs and DVC identifiers for all of the most Frequent users in the system.

VOICE-TO-TEXT TRANSMISSION SYSTEM WITH SELECTABLE VOICE CHARACTERISTICS THAT CAN INDICATE A TRANSMISSION BY A

STRANGER TO THE SYSTEM

by Hans Christopher Sowa

SYSTEM BACKGROUND:

THE SOLUTION:

  Voice recognition is used to turn voice to text so that just the text and a digital voice characteristic (DVC) of the voice can be transmitted by a radio. The receiving radio would combine the text and the DVC to recreate the audio. The most frequent users of the system would not send their DVC on the air. They would send a DVC identifier on the air instead of sending the DVC to save bandwidth. The most frequent users of the system would store in their radios all of the DVCs and DVC identifiers for all of the most Frequent users in the system.

  The radio should analyze the voice of the radio user and determine if the DVC of the user matches the authorized user's DVC. Upon realizing that an unauthorized user is transmitting with the radio, the DVC used for the transmission would be a spe- cial DVC set aside for unauthorized users. Other radio users in the system would recognize the voice as the unauthorized user voice and take corrective action. Another option is to not allow the radio to transmit ifthe DVC ofthe user cannot be identified by the radio.

THE PROBLEM

An unauthorized user of a radio could transmit and thus represent themselves as an authorized user.
