Abstract

Apparatus, computer-readable storage medium, and method associated with speech recognition are described. In embodiments, a mobile phone may include a processor; and a speech recognition module coupled with the processor. The voice recognition module may be configured to recognize one or more voice commands and may include first echo cancellation logic and second echo cancellation logic to be selectively employed during recognition of voice commands. Employment of the first and second echo cancellation logic respectively may cause the mobile phone to variably consume a first and second amount of energy, with the second amount of energy being less than the first amount energy.

Claims

1. A mobile phone comprising:

a processor; and

a speech recognition module coupled with the processor, wherein the speech recognition module is configured to recognize one or more voice commands and includes first echo cancellation logic and second echo cancellation logic to be selectively employed during recognition of voice commands, and wherein employment of the first and second echo cancellation logic respectively cause the mobile phone to variably consume first and second amount of energy, with the second amount of energy being less than the first amount energy.

2. The mobile phone of claim 1, wherein the first and second echo cancellation logic are respectively configured to operate at first and second sampling rate, with the second sampling rate being a lower sampling rate than the first sampling rate.

3. The mobile phone of claim 1, wherein the first echo cancellation logic includes non-linear processing logic and the second echo cancellation logic omits the non-linear processing logic.

4. The mobile phone of claim 1, wherein the speech recognition module is further configured to determine a rendering delay between when an audio stream is processed by the mobile phone and when the audio stream is rendered by a remote speaker coupled with the mobile phone;

wherein the first and second echo cancellation logic are configured to incorporate the rendering delay into one or more calculations.

5. The mobile phone of claim 1, wherein the speech recognition module is configured to employ the second echo cancellation logic, while the mobile phone is in a low power state.

6. The mobile phone of claim 1, wherein the mobile phone further comprises a speaker and a microphone, wherein the speech recognition module is further coupled with both the speaker and the microphone, and configured to employ the second echo cancellation logic whenever the speaker is not outputting audio contemporaneously captured by the microphone.

7. The mobile phone of claim 1, wherein the speech recognition module is further configured to selectively initiate a private mode or a group mode of a conversational user interface (CUI) of the mobile phone in response to a first voice command or a second voice command, respectively, while the user is engaged in a voice or video call with one or more participants using the mobile phone.

8. The mobile phone of claim 7, wherein the private mode is configured to exclude the one or more participants from interaction with the CUI, and the group mode is configured to include the one or more participants, as well as the user, in interaction with the CUI.

9. The mobile phone of claim 7, wherein the first and second voice commands comprise a first and second voice trigger, respectively.

10-25. -25. (canceled)

26. One or more computer-readable media having instructions stored thereon which, when executed by a mobile phone provide the mobile phone with a speech recognition module configured to:

receive a voice command from a user of the mobile phone, while the user is in a voice or video call with one or more participants;

determine if the voice command is associated with a private mode or a group mode of a conversational user interface (CUI); and

initiate the CUI in either the private mode or the group mode based upon the result of the determining.

27. The one or more computer-readable media of claim 26, wherein to initiate the CUI in either the private mode or the group mode further comprises exclusion of the one or more participants from the user'"'"'s interaction with the CUI or inclusion of the one or more participants from the user'"'"'s interaction with the CUI, respectively.

28. The one or more computer-readable media of claim 26, further comprising, selective employment of first and second echo cancellation logic wherein the first and second echo cancellation logic respectively cause the mobile phone to consume first and second amount of energy, with the second amount of energy being less than the first amount energy.

29. The one or more computer-readable media of claim 28, wherein the first and second echo cancellation logic are configured to respectively operate at a first and second sampling rate, with the second sampling rate being a lower sampling rate than the first sampling rate.

30. The one or more computer-readable media of claim 28, wherein the first echo cancellation logic includes non-linear processing logic and the second echo cancellation logic omits the non-linear processing logic.

31. The one or more computer-readable media of claim 28, wherein the speech recognition module is further configured to:

determine a rendering delay between when an audio stream is processed by the mobile phone and when the audio stream is rendered by a remote speaker coupled with the mobile phone; and

incorporate the rendering delay into first and second echo cancellation logic.

32. The one or more computer-readable media of claim 28, wherein the speech recognition module is further configured to employ the second echo cancellation logic, while the mobile phone is in a low power state.

33. The one or more computer-readable media of claim 28, wherein the speech recognition module is further configured to employ the second echo cancellation logic whenever a speaker of the mobile phone is not outputting audio contemporaneously captured by a microphone of the mobile phone.

34. The one or more computer-readable media of claim 26, wherein the voice commands comprise a voice trigger.

35. A computer-implemented method comprising:

selectively initiating, by a speech recognition module, a private mode of a conversational user interface (CUI) in response to a first voice command or initiate a group mode of the CUI in response to a second voice command, while the user is engaged in a voice or video call with one or more participants using the mobile phone; and

selectively employing, by the speech recognition module, first echo cancellation logic and second echo cancellation logic, wherein employment of the first and second echo cancellation logic respectively cause the mobile phone to consume a first and second amount of energy, with the second amount of energy being less than the first amount energy.

36. The computer-implemented method of claim 35, wherein the private mode excludes the one or more participants from interaction with the CUI and the group mode includes the one or more participants, as well as the user, in interaction with the CUI.

37. The computer-implemented method of claim 35, wherein the first and second echo cancellation logic respectively operate at first and second sampling rate, with the second sampling rate being a lower sampling rate than the first sampling rate.

38. The computer-implemented method of claim 37, wherein the first echo cancellation logic includes non-linear processing logic and the second echo cancellation logic omits the non-linear processing logic.

39. The computer-implemented method of claim 35, further comprising determining a rendering delay between when an audio stream is processed by the mobile phone and when the audio stream is rendered by a remote speaker coupled with the mobile phone;

wherein the first and second echo cancellation logic is configured to incorporate the rendering delay into one or more calculations.

40. The computer-implemented method of claim 35, further comprising employing the second echo cancellation logic, while the mobile phone is in a low power state.

41. The computer-implemented method of claim 35, wherein the first and second commands comprise first and second voice triggers respectively.
