Voice interactive method and system
First Claim
1. A voice interactive method comprising:
- a) performing voice recognition upon an input voice signal to detect presence of a predetermined keyword;
b) upon detecting that the input voice signal contains the predetermined keyword, performing semantic recognition upon the input voice signal;
c) generating a response according to result of the semantic recognition performed in step b);
d) simultaneous with step b), calculating an idle time between a current input voice signal and a previous input voice signal; and
e) disabling the semantic recognition of the input voice signal, and repeating step a) when the idle time calculated in step d) is larger than a predetermined threshold.

Abstract
In a voice interactive system, a detecting module detects presence of a predetermined keyword in an input voice signal. When the presence of the predetermined keyword is detected, the detecting module switches operation of a semantic recognition module from a disabled mode to an enabled mode, where the semantic recognition module performs semantic recognition upon the input voice signal. A response module generates a response according to result of the semantic recognition. A timer module operates simultaneously with operation of the semantic recognition module in the enabled mode so as to calculate and determine whether an idle time between a current input voice signal and a previous input voice signal is larger than a predetermined threshold. In the affirmative, a mode switching module enables the detecting module to switch operation of the semantic recognition module back to the disabled mode.
