Abstract: This application relates to the artificial intelligence (AI) field, and specifically, to a voice quality enhancement method and a related device. The method includes: after a PNR mode is enabled, obtaining a noisy voice signal and target voice-related data, where the noisy-carrying voice signal includes a voice signal of a target user and an interfering noise signal, and the target voice-related data indicates a voice feature of the target user; and performing noise reduction on the noisy voice signal based on the target voice-related data by using a trained voice noise reduction model to obtain a noise-reduced voice signal of the target user, where the voice noise reduction model is implemented based on a neural network. In embodiments of this application, voice of a target person can be enhanced, and interference can be suppressed.

Abstract: Embodiments of this application provide an audio data processing method and apparatus, and a sound box system, which are related to the field of audio technologies, and improve sound quality of an audio playing device. The sound box system includes a full-frequency sound box and a low-frequency sound box. The full-frequency sound box is physically connected to the low-frequency sound box by using a first fastening part of the full-frequency sound box and a second fastening part of the low-frequency sound box. Furthermore, the full-frequency sound box communicates with the low-frequency sound box by using a first communication part of the first fastening part and a second communication part of the second fastening part, where the first fastening part and the second fastening part are a group of paired connection parts, and the first communication part and the second communication part are a group of paired communication parts.

Abstract: A method, device and system for judging a call type are disclosed in embodiments of the present invention. The method includes: receiving a call request from a calling terminal, where the call request carries a calling terminal number and a called terminal number; querying a number information storage server for plan information of the calling terminal number and/or the called terminal number according to the call request; and judging the call type of a call service corresponding to the call request according to the plan information of the calling terminal number and the called terminal number. In the embodiments of the present invention, a number information storage server stores and manages the number plan information uniformly, thus reducing the maintenance costs; and the method, device and system for judging a call type enable judging of the call type of a terminal.
