Abstract
A radio communication system includes a voice recognition system (218), a transmitter (202) and a processing system (210). The voice recognition system is utilized for receiving caller initiated messages, and the transmitter is used for transmitting messages to a plurality of SCRs (selective call radios) (122) of the radio communication system. The processing system, which is coupled to the voice recognition system, and the transmitter, is adapted to cause the voice recognition system to convert a voice signal representative of a voice message originated by a caller of the radio communication system to a text message (401, 417), wherein the text message is intended for a SCR, to then generate a likelihood of success that the voice signal has been flawlessly converted to a text message, to have a human listen to an audible representation of the voice signal, and to cause the transmitter to transmit the text message to the SCR (432). The converting step includes autocorrelation by Fourier transform, measure a degree of voiceness for each band, applying the degree of voiceness to a corresponding plurality of phenome models, and deriving a text equivalent by searching through a phenome…
