Abstract: A portable radio may include a radio frequency (RF) transmitter, an RF receiver, and an audio input transducer. A controller may store command messages and speech messages, implement a stand-alone, speech recognition and text-to-speech (TTS) function for the stored command messages and stored speech messages. The controller may also control at least one of an RF transmitter and RF receiver of a remote radio based upon an input command matching one of the stored command messages using the audio input transducer and the stand-alone speech recognition and TTS function, and convert a speech message matching one of the stored speech messages into a text message. The RF transmitter may send the text message to the remote receiver.

A controller may store command messages and speech messages, implement a stand-alone, speech recognition and text-to-speech (TTS) function for the stored command messages and stored speech messages. The controller may also control at least one of an RE transmitter and RF receiver of a remote radio based upon an input command matching one of the stored command messages using the audio input transducer and the stand-alone speech recognition and TTS function, and convert a speech message matching one of the stored speech messages into a text message. The RF transmitter may send the text message to the remote receiver.

Abstract: A communications system includes a first communications device cooperating with a second communications device. The first communications device multiplexes a digital speech message and a corresponding text message into a multiplexed signal, and wirelessly transmits the multiplexed signal. The second communications device wirelessly receives the multiplexed signal, de-multiplexes the multiplexed signal digital into the speech message and the corresponding text message, decodes the speech message for an audio output transducer, and operates a text processor on the corresponding text message for display. The corresponding text message is displayed in synchronization with the speech message output by the audio output transducer. A memory is coupled to the text processor for storing the text message, and the text processor is configured to display the stored text message.
