Abstract

A method for dual channel monitoring on a radio device as provided enables efficient use of communication network resources. The method includes receiving at the radio device a first speech signal over a first channel, while simultaneously receiving at the radio device a second speech signal over a second channel. The first speech signal is then processed at the radio device to generate a text transcription of the first speech signal, and the text transcription of the first speech signal is displayed on a display screen of the radio device. An audible voice signal is then produced from a speaker that is operatively connected to the radio device simultaneously with displaying the text transcription of the first speech signal.

Claims

1. A method for dual channel monitoring on a radio device, the method comprising:

receiving at the radio device a first speech signal over a first channel;

receiving at the radio device, simultaneously with the first speech signal, a second speech signal over a second channel;

processing the first speech signal at the radio device to generate a text transcription of the first speech signal;

displaying the text transcription of the first speech signal on a display screen of the radio device; and

producing from the second speech signal an audible voice signal from a speaker that is operatively connected to the radio device, wherein producing the audible voice signal is performed simultaneously with displaying the text transcription of the first speech signal.

2. The method of claim 1, wherein processing the first speech signal at the radio device to generate a text transcription of the first speech signal comprises use of speech to text software.

3. The method of claim 1, wherein the first channel is a stealing channel of the second channel and the first speech signal comprises coded text that was previously transcribed using speech to text software.

4. The method of claim 1, further comprising transmitting a third speech signal from the radio device over the second channel using a push to talk feature of the radio device.

5. The method of claim 1, wherein the first channel and the second channel are distinct logical channels multiplexed over a single physical channel.

6. The method of claim 1, wherein the first channel and the second channel are time division multiple access channels.

7. The method of claim 1, wherein the first channel is used by a first talk group having multiple users.

8. The method of claim 7, wherein the second channel is used by a second talk group having multiple users.

9. The method of claim 1, wherein both the first channel and the second channel are transmitted from a single repeater station.

10. A radio device, comprising:

computer readable program code components configured to cause receiving, at the radio device, a first speech signal over a first channel;

computer readable program code components configured to cause receiving, at the radio device, simultaneously with the first speech signal, a second speech signal over a second channel;

computer readable program code components configured to cause processing the first speech signal, at the radio device, to generate a text transcription of the first speech signal;

computer readable program code components configured to cause displaying the text transcription of the first speech signal on a display screen of the radio device; and

computer readable program code components configured to cause producing from the second speech signal an audible voice signal from a speaker that is operatively connected to the radio device, wherein producing the audible voice signal is performed simultaneously with displaying the text transcription of the first speech signal.

11. The radio device of claim 10, wherein processing the first speech signal, at the radio device, to generate a text transcription of the first speech signal comprises use of speech to text software.

12. The radio device of claim 10, wherein the first channel is a stealing channel of the second channel and the first speech signal comprises coded text that was previously transcribed using speech to text software.

13. The radio device of claim 10, further comprising computer readable program code components configured to cause transmitting a third speech signal from the radio device over the second channel using a push to talk feature of the radio device.

14. The radio device of claim 10, wherein the first channel and the second channel are distinct logical channels multiplexed over a single physical channel.

15. The radio device of claim 10, wherein the first channel and the second channel are time division multiple access channels.

16. The radio device of claim 10, wherein the first channel is used by a first talk group having multiple users.

17. The radio device of claim 16, wherein the second channel is used by a second talk group having multiple users.

18. The radio device of claim 10, wherein both the first channel and the second channel are transmitted from a single repeater station.

19. A radio device, comprising:

means for receiving at the radio device a first speech signal over a first channel;

means for receiving at the radio device, simultaneously with the first speech signal, a second speech signal over a second channel;

means for processing the first speech signal at the radio device to generate a text transcription of the first speech signal;

means for displaying the text transcription of the first speech signal on a display screen of the radio device; and

means for producing from the second speech signal an audible voice signal from a speaker that is operatively connected to the radio device, wherein producing the audible voice signal is performed simultaneously with displaying the text transcription of the first speech signal.
