1. A method comprising:
- receiving an acoustic input signal at a speech recognizer;
identifying a user that is speaking based on the acoustic input signal;
determining speaker-specific information previously stored for the user;
determining, by a computing device, a set of responses based on the recognized acoustic input signal and the speaker-specific information for the user;
determining if the response should be output; and
outputting the response if it is determined the response should be output.

Abstract
In one embodiment, a method includes receiving an acoustic input signal at a speech recognizer. A user is identified that is speaking based on the acoustic input signal. The method then determines speaker-specific information previously stored for the user and a set of responses based on the recognized acoustic input signal and the speaker-specific information for the user. It is determined if the response should be output and the response is outputted if it is determined the response should be output.

16. A method comprising:
-
receiving a signal from a first stage recognizer based on recognition of an acoustic input signal and classification of portions of the acoustic input signal into a classification in a plurality of classifications using a first speech recognition algorithm, the first stage recognizer being configured to recognize the acoustic input signal in an always on mode; activating, by a computing device, the second stage recognizer upon receiving the signal to recognize the acoustic input signal, the second stage recognizer configured to use a second speech recognition algorithm; identifying a user that is speaking based on the acoustic input signal; determining speaker-specific information previously stored for the user; determining a response to the recognized acoustic input signal based on the speaker-specific information; determining if the response should be output based on a ranking of the response; and outputting the response if it is determined the response should be output. - View Dependent Claims (17, 18, 19, 20)

21. A system comprising:
-
a first stage recognizer configured to recognize the acoustic input signal using a first speech recognition algorithm in an always on mode, the first stage recognizer configured to; receive an acoustic input signal; identify a user that is speaking based on the acoustic input signal; determine speaker specific information previously stored for the user; classify portions of the acoustic input signal into different classifications using a first speech recognition algorithm; determine a second stage recognizer should be triggered based on a selection of a classification based on classified portions being classified with the selected classification and the speaker-specific information; and a second stage recognizer configured to; receive a signal from the first stage recognizer to activate the second stage recognizer; activate the second stage recognizer upon receiving the signal to recognize the acoustic input signal, the second stage recognizer configured to use a second speech recognition algorithm different from the first speech recognition algorithm to recognize the acoustic input signal; determine a response to the recognized acoustic input signal using the speaker-specific information; determine if the response should be output based on a ranking of the response; and output the response if it is determined the response should be output. - View Dependent Claims (22, 23)

24. A method comprising:
-
receiving a trigger phrase; activating a speech recognizer based on receiving the trigger phrase; receiving an acoustic input signal at the speech recognizer; identifying a user that is speaking based on the acoustic input signal or the trigger phrase; determining speaker-specific information previously stored for the user; determining, by a computing device, a set of responses based on the recognized acoustic input signal and the speaker-specific information for the user; and outputting the response if it is determined the response should be output. - View Dependent Claims (25, 26, 27)
