Abstract: A speech processing method, a device and a storage medium. The method includes: segmenting (401) to-be-processed speech according to role change point information in the to-be-processed speech to obtain multiple speech segments, where the role change point information is used to indicate a position where a speaking role changes in the to-be-processed speech, the multiple speech segments include multiple first segments and at least one second segment, and a length of any first segment is greater than a length of any second segment; performing (402) clustering on the multiple first segments, and assigning the at least one second segment to a class obtained after the clustering, to obtain a role separation result of the to-be-processed speech. The accuracy and stability of role separation are improved effectively.

Abstract: The present disclosure relates to an audio signal processing method and apparatus, a device and a storage medium. The present disclosure performs a segmenting processing on an audio signal to obtain multiple audio segments, performs a clustering processing on the multiple audio segments according to feature information of each audio segment in the multiple audio segments to obtain one or more first sets, determines a first cluster center of each first set according to the feature information of the audio segment included in each first set, and performs a clustering processing on the multiple audio segments according to the first cluster center of each first set to obtain one or more second sets, where audio segments in a same second set corresponding to a same role label. In this way, an accuracy of an unsupervised role separation based on a single channel speech is improved.

Abstract: An automatic steering device of an agricultural machine is provided, which is connected with a steering axle of the agricultural machine and comprises: a data acquisition unit for acquiring data information of the agricultural machine, the data information comprises an actual steering angle value, a travelling position and a travelling direction; a driving unit for providing a rotating torque; a steering unit connected with the driving unit and the steering axle and used for transmitting the rotating torque to the steering axle; and a control unit connected with the data acquisition unit and the driving unit, used for obtaining a steering angle value according to the data information of the agricultural machine, and controlling the driving unit according to the steering angle value. The embodiments have simple structure, can be suitable for the agricultural machine with different steering angle ranges, and have high efficiency and simple operation.
