Description
Technical Field
The invention relates to the technical field of voice interaction, in particular to a method for reducing false awakening of intelligent voice interaction.
Background
In an intelligent home environment, more and more electronic products can perform voice interactive operation by utilizing voice control. For example, the smart sound box can be woken up by speaking a preset wake-up word when in a sleep state, and then receives a voice instruction sent by a user to perform voice interaction. The problem exists at present that a series of products of the same merchant are provided with the same awakening word, so that in a scene with a plurality of products, any person utters the awakening word to awaken all devices in an awakening range, and the phenomenon of 'advocation of Baihe' occurs. However, usually, the main control device determines the awakened device through the authorization request module, and returns authorization information through one-to-one link (e.g., pairing) between the main control device and the interactive device, thereby ensuring that one device is awakened, thereby implementing one-to-one. The core of this method is the centralized control of the master device. The master control center is allowed to determine authorization, the center is excessively relied on, and the problem that the whole master control device cannot be used when an abnormal state occurs is solved.

when the intelligent voice equipment generating the token is disconnected, the token is automatically generated by the other intelligent voice equipment which accords with the preset rule; the synchronization and query mechanism ensures that a ring network structure with a token is finally formed to ensure the uniqueness of the responding device;
step S200: performing voiceprint registration on the intelligent voice equipment: when the intelligent voice equipment has the token, starting voiceprint registration, otherwise, continuously waiting until the token is transmitted to the intelligent voice equipment and then carrying out voiceprint registration; if the response of other intelligent voice equipment with the token is caused, the intelligent voice equipment with the token is suppressed by adopting a suppression language, so that the token is continuously transmitted and is known to be transmitted to equipment needing voiceprint registration; in the voiceprint registration process, other equipment can be offline through manual operation, so that only the current equipment in the environment has the token;
step S300: and awakening the intelligent voice equipment by the user who successfully registers the voiceprint by adopting an awakening word, waiting for the token by the intelligent voice equipment which receives the voice signal, executing the voice instruction of the user after the token is possessed, and releasing the token after the user operation is finished.
And the device with the token is awakened by adopting the voiceprint, so that the uniqueness of the awakened device is ensured. When the intelligent voice equipment generating the token is disconnected or abnormal, the next intelligent voice equipment generating the token is automatically determined according to the preset rule, the token is generated and circularly transmitted, and the design of a centralization and fault-tolerant error correction mechanism is removed, so that the excessive dependence on the central equipment is removed.
Further, the preset rule is as follows: the intelligent voice equipment with the equipment serial number as the lowest value in the equipment table generates a token; the preset transfer rule is as follows: the token is circularly transmitted in a mode that the serial number of the device is from low to high and then from highest to lowest. The preset rule and the preset delivery rule may also be other sorting manners of other fields, and the scheme is not limited to this rule.
Further, the intelligent voice device comprises a main control module, a broadcasting module, a token module, a voiceprint registration module, a voiceprint verification module and a voice content identification module, wherein:
the broadcasting module is used for broadcasting self state information to the local area network, wherein the state information comprises a device serial number, an ip address, a mac address and broadcasting time;
