As described in detail below.
S101, searching a wireless network by the sound equipment; and S103, adding the searched wireless network into a network list by the sound equipment.
In this embodiment, the Wireless Network is, for example, a WLAN (Wireless Local Area Network), and networking devices are interconnected by using a Wireless communication technology to form a Network system capable of communicating with each other and implementing resource sharing. The wireless local area network is essentially characterized in that each device is not connected with the network by using a communication cable any more, but is connected in a wireless mode, so that the construction of the network and the movement of the terminal are more flexible.
Wireless local area networks based on the IEEE802.11 standard allow wireless connectivity in a local area network environment using the 2.4GHz or 5GHz radio frequency bands in the ISM band, which may not necessarily be licensed. They are widely used, from home to business to Internet access hotspots.
Voice interaction is one of key factors for distinguishing traditional intelligent products from intelligent sound boxes. Compare in early intelligent audio amplifier, present intelligent audio amplifier, intelligent screen have had completely different experience in speech recognition and smoothness, and mutual experience is more and more random and natural. In the field of interaction, it is the extremely guest mode (i.e., continuous dialogue technique) that changes the harsh scene of a question-and-answer for the first time. The extremely-guest mode realizes continuous conversation between people and the intelligent sound box, and greatly improves the experience that people cannot have multiple conversations and repeatedly awaken for multiple times in the prior man-machine interaction, the problem that answers are hard and the like.
What makes intelligent audio amplifier human-computer interaction appear "the matter become" is full duplex exempts from to awaken up the technique, has not only realized "once awakening up, the multiple round is interactive", can also realize human-computer interaction when talkying with other people noninterference each other, chat with the machine more and more like the natural interaction between people. The emergence of full-duplex wake-up-free technology is a milestone event for smart speakers. Before that, the user mostly needs to wake up the intelligent sound box once every time of giving an instruction, although continuous conversation can be realized in a specific scene under the extremely guest mode, the application scene is very limited, and the understanding and expression capability of the sound box is far inferior to that of human beings. Full duplex wake-up-free enables the communication capacity of the intelligent sound box to be leaped once.
The intelligent sound box mainly comprises a main control board, a communication component, a microphone array, a loudspeaker, a key, a light indicator, a processor, a memory, a Flash storage, a WiFi communication chip and the like on hardware. The intelligent sound box is more concentrated in speech processing, and the microphone is more, has constituted the array, and audio amplifier loudspeaker are more, and the sound chamber is bigger, and tone quality is better. From the aspect of software, the intelligent sound box processes natural language spoken by human beings and then sends out corresponding control instructions or gives out voice feedback. The software mainly comprises: voice detection (VAD), noise reduction, wake-up, recognition (ASR), understanding (NLU), speech production (NLG), speech synthesis (TTS). The voice detection is used for judging whether human language exists or not, if the human language is detected, the noise reduction (including echo cancellation AEC, sound source localization DOA and beam forming BF) processing is carried out on the part of signals, then whether wake-up words exist or not is identified, if not, the wake-up words are discarded, and if yes, the interactive state is entered. The interactive state mainly comprises parts such as recognition (ASR), understanding (NLU), language production (NLG), speech synthesis (TTS) and the like. The recognition (ASR) and the understanding (NLU) mainly depend on cloud service, namely the intelligent sound box processes the voice signals and sends the processed voice signals to background cloud service, then recognition is carried out, the recognized voice signals are changed into words and phrases, the words and phrases are analyzed and recognized, and the intention of a user is understood. After understanding the intention, some control signals can be sent, relevant information can be searched, relevant content can be searched, then response language is generated, natural language is changed into natural language through voice synthesis, and the natural language is output by a loudspeaker of the intelligent sound box, so that the interactive process is completed.
The intelligent sound box provides the working principle of content and service: supposing that a consumer sends an instruction of inquiring the air tickets from A to B to the intelligent sound box, a voice interaction system of the intelligent sound box collects voice, reduces noise, identifies awakening words and converts voice signals into digital signals through a voice algorithm local processing unit and an audio decoding unit, then the processed digital signals are uploaded to a cloud server, the cloud server carries out voice digital coding identification and semantic understanding, then the information in an air ticket reservation database is called to be transmitted to the intelligent sound box, and the digital signals are restored into the voice signals through an audio effect unit and played by the intelligent sound box.
The intelligent sound box controls the working principle of the intelligent home: supposing that a consumer sends an instruction of turning off an electric lamp to an intelligent sound box, the intelligent sound box carries out semantic understanding on voice digital codes through a cloud server after voice collection and voice recognition, and feeds back obtained information to a home router, the control instruction is broadcasted through the router, intelligent home equipment has unique IP numbers, the intelligent home can identify whether the instruction relates to the IP number of the intelligent home equipment, and finally the instruction of turning off the electric lamp is finished after socket recognition of the electric lamp is finished.
The intelligent voice interaction system of the intelligent sound box is a key technology for realizing the intellectualization of the intelligent sound box, and the intelligent voice interaction system needs to be provided with: 1) far field recognition, 2) awakening of awakening words, 3) voice recognition, and 4) semantic understanding. Any device supporting the intelligent voice interaction system can become a control center taking voice as a medium, so that the intelligent voice box can be applied to automobiles, mobile phones and wearable devices.

When the sound equipment is connected with a certain wireless network, the speed of the connection with the wireless network is recorded and stored in a network list. If the signal intensity of a plurality of wireless networks is greater than the signal intensity threshold value, the wireless networks basically meet the requirements, and the network which is connected with the wireless networks and has the maximum connection speed is selected from the wireless networks for connection, so that the wireless networks can be connected with the proper wireless network with the high connection speed, and the user experience is provided.
In some embodiments, the sound control method further includes: after the sound equipment is connected with the first wireless network, periodically detecting whether the connection speed is greater than a connection speed threshold value, and if the connection speed is less than the connection speed threshold value, reselecting the wireless network from the network list for connection. According to the method and the device, the wireless network is reselected for connection instead of being reselected for connection after the network connection is disconnected, whether the connection speed is greater than the connection speed threshold value or not is actively monitored, and if the connection speed is less than the connection speed threshold value, the wireless network is reselected from the network list for connection, so that the time of network interruption can be shortened and the user experience is improved when the network is abnormal.
