Description
Technical Field
The application relates to a method for adjusting a voice wake-up threshold.
Background
Some of the electronic devices having a sound collection unit (e.g., a microphone) provide a voice wake-up function. The voice wakeup (keyword spotting) refers to switching an electronic device from a sleep state to an operation state once the electronic device detects that a voice of a specific keyword (called a wakeup word) appears, so as to implement a mutual conversation, or execute an instruction of a subsequent voice, and the like. In smart audio amplifier, smart mobile phone, the smart watch that has the microphone, the intelligent bracelet that has the microphone, often be equipped with the pronunciation and awaken up the function. The quality of the voice awakening function directly determines the voice experience of the intelligent equipment. Voice wake-up ensures both correct wake-up when a wake-up word is detected and no wake-up when other sounds are received.
The voice wake-up threshold is a threshold for determining whether the voice detection unit is working. After the sound collection unit collects the audio signal, the voice detection unit carries out voice activation detection to judge whether the audio signal contains the specific keyword or not only when the energy of the audio signal is greater than or equal to the voice awakening threshold value. The prior art generally adjusts the voice wake-up threshold by determining the time, for example, raising the voice wake-up threshold at night, so as to prevent the electronic device from being mistakenly woken up at night and disturbing the user. However, it is hard to adjust the voice wake-up threshold only according to the time, and there is a large deviation for users with different work and rest laws.

Detailed Description
Referring to fig. 1, the method for adjusting a voice wake-up threshold based on router traffic provided by the present application includes the following steps.
Step S1: the voice wake-up device acquires the traffic of the specified device in the latest period of time through the connected router.
The voice awakening device is an intelligent electronic device with a voice awakening function, such as an intelligent sound box, an intelligent mobile phone, an intelligent watch with a microphone, an intelligent bracelet with a microphone, and the like.
The designated equipment and the voice awakening equipment are connected with the same router. The designated device may be the voice wake-up device itself, or may be other electronic devices connected to the router, such as a mobile phone, a desktop computer, a notebook computer, a tablet computer, an intelligent television, an intelligent projector, a game console, and the like, and may be set by a user.
The obtaining of the traffic of the specified device in the latest period may be obtaining the traffic of one specified device in the latest period; or the sum of the flow rates of a plurality of specified devices in the latest period of time, or the maximum flow rate value, or the minimum flow rate value, or the average flow rate value can be obtained; the total flow, or the maximum flow value, or the minimum flow value, or the average flow value of all the electronic devices connected with the router in the last period of time can be obtained; can be set by the user.
The latest period of time may be, for example, the latest 1 second, the latest 3 seconds, the latest 5 seconds, the latest 10 seconds, the latest 15 seconds, the latest 30 seconds, the latest 1 minute, the latest 3 minutes, the latest 5 minutes, the latest 10 minutes, the latest 15 minutes, the latest 30 minutes, the latest 1 hour, or the like, and may be set by the user.
Step S2: and the voice awakening equipment determines and updates the current voice awakening threshold value according to the acquired flow value. The general principle is as follows: if the acquired flow value is high, indicating that the user is likely to be in an active state, the voice wake-up threshold is made a conventional value. If the acquired flow value is low, indicating that the user is likely to be in a resting (e.g., sleeping) state, the voice wake-up threshold is increased over a conventional value. Raising the voice wake-up threshold helps to reduce the false wake-up rate, but also reduces the wake-up rate; when the acquired flow value is low, the user is likely to be in a rest or sleep state, and the intelligent device is not required to be awakened by voice, so that the awakening rate is reduced, and the voice awakening experience is not influenced.
In step S2, a flow rate determination threshold is set. When the acquired flow value is larger than the flow judgment threshold value, the acquired flow value is considered to be higher; and when the acquired flow value is smaller than the flow judgment threshold value, the acquired flow value is considered to be lower. When the acquired flow value is equal to the flow judgment threshold value, it can be classified as any of the above cases.
In step S2, the voice wakeup threshold has two values, which are respectively referred to as a normal value and a raised value. When the acquired flow value is higher, updating the voice awakening threshold value to a conventional value; and when the acquired flow value is lower, updating the voice awakening threshold value to an improved value.
Referring to fig. 2, the voice wake-up threshold adjusting system based on router traffic provided by the present application includes a traffic obtaining unit 1 and a threshold adjusting unit 2. The system shown in fig. 2 corresponds to the method shown in fig. 1.
The traffic acquiring unit 1 is used for acquiring the traffic of the specified device in the latest period through the router connected with the voice wake-up device.
The threshold adjusting unit 2 is configured to determine and update a current voice wake-up threshold of the voice wake-up device according to the acquired flow value. And if the acquired flow value is higher, the voice awakening threshold value is made to be a conventional value. If the acquired flow value is low, the voice wake-up threshold is increased on the basis of a conventional value.
According to the method and the system for adjusting the voice awakening threshold based on the router flow, the router is used for obtaining the flow data, and the user is judged to be in an active state or a rest state according to the assistance of the flow data, so that the voice awakening threshold is set to be a conventional value or a raised value in a targeted manner, and the probability that the voice awakening equipment is awakened by mistake when the user is in rest is reduced.
The above are merely preferred embodiments of the present application and are not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
