An implementation scheme is: when the noise elimination algorithm is debugged, acquiring multiple voice control signals from a vehicle to be debugged, modifying a weight of a configuration parameter of the noise elimination algorithm in a digital signal processing to obtain an updated noise elimination algorithm; then adopting the updated noise elimination algorithm to perform noise elimination processing on the multiple voice control signals; if control results of noise-eliminated voice control signals on the vehicle to be debugged do not meet a preset condition, continuing to modify the weight of the configuration parameter until the preset condition is met, and then sending a noise elimination algorithm that meets the preset condition to the vehicle to be debugged. | 2021-10-21 |
| 20210327452 | Methods, Apparatus and Systems for Low Latency Audio Discontinuity Fade Out - The present document discloses a method for fading discontinued audio feeds for replay by a speaker. In particular, the method may first comprise receiving an input audio feed comprising a plurality of samples. The method may further comprise determining whether the input audio feed is discontinued. And, when discontinuity of the input audio feed is detected, the method may comprise generating an intermediate audio signal comprising a plurality of samples based on the discontinued input audio feed. In particular, the intermediate audio signal may be generated based on a last portion of the discontinued input audio feed that has been output for replay. In addition, the method may further comprise applying a fadeout function to the intermediate audio signal to generate a fadeout audio signal. Finally, the method may comprise outputting the fadeout audio signal for replay by the speaker. | 2021-10-21 |
| 20210327453 | AUDIO VISUAL CORRESPONDENCE BASED SIGNAL AUGMENTATION - A system includes a headset to capture sound and a visual signal of a local area including one or more sound sources.

An anomaly detection apparatus includes an anomaly degree estimating unit configured to estimate an anomaly degree indicating a degree of anomaly of anomaly detection target equipment from sound emitted from the anomaly detection target equipment (hereinafter, referred to as anomaly detection target sound) based on association between a first probability distribution indicating distribution of normal sound emitted from one or more pieces of equipment different from the anomaly detection target equipment and normal sound emitted from the anomaly detection target equipment (hereinafter, referred to as normal sound for adaptive learning). | 2021-10-21 |
| 20210327457 | METHOD AND SYSTEM FOR A HEADSET WITH PROFANITY FILTER - A gaming headset receives a plurality of audio channels comprising game audio channels and a chat audio channel during play of a particular game. The gaming headset monitors the received audio channels for predefined words that are associated with particular sounds in a data structure, and in response to detecting predefined words, filters out at least a portion of the detected predefined words from the received plurality of audio channels. The monitoring compares sounds on the received audio channels with the particular sounds in the data structure and also performs signal analysis on the audio channels during game play to detect the occurrence of the predefined words. The filtering mutes one or more of the plurality of audio channels so that the detected occurrence of the one of the predefined words is not output via speakers of the gaming headset. | 2021-10-21 |
