Method and apparatus for processing an input speech signal during presentation of an output audio signal

A method for processing an input speech signal during presentation of an output audio signal, the method comprising steps of:

• detecting the input speech signal;
• determining an identification corresponding to the output audio signal;
• and
• providing the identification to establish a context in responding to the input speech signal.

In a subscriber unit in wireless communication with an infrastructure comprising a speech recognition server, the subscriber unit comprising a speaker and a microphone, wherein the speaker provides an output audio signal and the microphone provides an input speech signal, a method for processing the input speech signal, the method comprising steps of:

• detecting a start of the input speech signal during presentation of the output speech signal;
• determining, relative to the output audio signal, an input start time of the start of the input speech signal;
• and
• providing the input start time to the speech recognition server as a control parameter.

In a subscriber unit in wireless communication with an infrastructure comprising a speech recognition server, the subscriber unit comprising a speaker and a microphone, wherein the speaker provides an output audio signal and the microphone provides an input speech signal, a method for processing the input speech signal, the method comprising steps of:

• detecting the input speech signal during presentation of the output audio signal;
• determining an identification corresponding to the output audio signal;
• and
• providing the identification to the speech recognition server as a control parameter.

In a speech recognition server forming a part of an infrastructure that wirelessly communicates with one or more subscriber units, a method for providing information signals to a subscriber unit of the one or more subscriber units, the method comprising steps of:

• causing an output audio signal to be presented at the subscriber unit;
• receiving, from the subscriber unit, at least an input start time corresponding to a start of an input speech signal relative to the output audio signal at the subscriber unit;
• and
• responsive at least in part to the input start time, providing the information signals to the subscriber unit.

In a speech recognition server forming a part of an infrastructure that wirelessly communicates with one or more subscriber units, a method for providing information signals to a subscriber unit of the one or more subscriber units, the method comprising steps of:

• causing an output audio signal to be presented at the subscriber unit, wherein the output audio signal has a corresponding identification;
• receiving, from the subscriber unit, at least the identification when an input speech signal is detected at the subscriber unit during presentation of the output audio signal;
• and
• responsive at least in part to the identification, providing the information signals to the subscriber unit.

A subscriber unit that wirelessly communicates with an infrastructure comprising a speech recognition server, the subscriber unit comprising a speaker and a microphone, wherein the speaker provides an output audio signal and the microphone provides an input speech signal, the subscriber unit further comprising:

• means for detecting a start of the input speech signal;
• means for determining, relative to the output audio signal, an input start time of the start of the input speech signal;
• and
• means for providing the input start time to the speech recognition server as a control parameter.
