  • Patent number: 10714114
    Abstract: The present disclosure provides a noise reduction processing method, system and terminal device. In the present disclosure, a position angle of a far-field audio input sound source and a microphone array as well as a rotation angle of a head servo of a robot are obtained, and then a target rotation angle of the robot is calculated. The head servo of the robot is controlled to rotate according to the target rotation angle such that the robot moves along with the far-field sound source, and a beam area is changed according to the target rotation angle to enable a sound source enhancement area to process far-field audios. As a result, the noise reduction performance of the microphone array beam is effectively improved.

  • Publication number: 20200074992
    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.

  • Publication number: 20190361664
    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.
