Controller for voice-controlled device and associated method

摘要

A controller for a voice-controlled device is provided. The controller includes a setting module and a recognition module. The setting module generates a threshold according to an environmental parameter. The recognition module compares a confident score of speech recognition with the threshold to accordingly execute voice control.

1. A controller for a voice-controlled device, comprising:
an environment detector, configured to detect an environment to obtain an environmental parameter associated with a volume value; a setting module, configured to set a threshold according to the environmental parameter, wherein the setting module sets the threshold to a higher threshold when the volume value is higher and sets the threshold to a lower threshold when the volume value is lower; and a recognition module, configured to receive a speech, to perform speech recognition on the speech to generate a confidence score of speech recognition, and to compare the confidence score of speech recognition with the threshold to generate a control signal.
