Abstract: The present disclosure discloses a method and an apparatus for judging termination of sound reception and a terminal device. The method including: performing a voice activity detection on a current sound clip to obtain a first value; performing a semantic relevance detection on the current sound clip and a next sound clip by deep learning to obtain a second value; performing a weighted calculation on the first value and the second value to obtain a third value; comparing the third value with a preset threshold; and determining whether sound reception of the current sound clip is terminated based on the comparison result.

Abstract: The present disclosure provides a robot and speech interaction recognition rate improvement circuit and method thereof. In the circuit, the main controller transmits a pre-recorded servo sound file to the first decoder in response to detecting the robot being in a motion state; the first decoder decodes the servo sound file to obtain a first sound analog signal of a servo sound; the analog-to-digital converter converts the first sound analog signal of the servo sound into a first sound digital signal, and converts a second sound analog signal collected by the microphone into a second sound digital signal; and the main controller further performs a suppression process on the servo sound in the second sound digital signal based on the first sound digital signal and the second sound digital signal. As a result, the influence of the sound of the servo of the robot is effectively reduced.
