Embodiment 1

[0038] This embodiment provides a wake-up word preset reliability threshold adjustment method, such as figure 1 shown, including steps:

[0039] S11. Acquiring user's daily use behavior data;

[0040] S12. Adjust the preset reliability threshold of the wake-up word according to the user's daily usage behavior data.

[0041] The wake word preset reliability threshold adjustment method in this embodiment is applied to a terminal device, which can be a mobile phone, a computer, a smart speaker, a toy, a home appliance, a digital broadcast terminal, a messaging device, a tablet device, a medical device, Fitness equipment, personal digital assistants, and any device with voice control.

[0042] The subject of execution of the wake word preset reliability threshold adjustment method in this embodiment is the above-mentioned terminal device.

[0043] It should be noted that the wake-up word is a word related to the voice control function of the terminal device, which is preset by ...

Embodiment 2

[0064] This embodiment provides a wake-up word preset reliability threshold adjustment system, such as figure 2 shown, including:

[0065] Data acquisition module 11, used to acquire user's daily use behavior data;

[0066] The adjustment module 12 is configured to adjust the preset reliability threshold of the wake-up word according to the user's daily use behavior data.

Abstract

The invention discloses a wake-up word preset confidence threshold adjustment method and system. The method comprises steps that S11, daily use behavior data of a user is obtained; S12, the wake-up word preset confidence threshold is adjusted according to the daily use behavior data. The method is advantaged in that the wake-up word preset confidence threshold is dynamically set and adjusted through acquiring the daily usage behavior data of the user, personal use characteristics of the user are fully considered, firstly, whether the preset confidence threshold is lowered overall is determinedthrough the daily behavior confidence average value of the user, the preset confidence threshold is further adjusted based on the use number for each time period, the device wake-up rate is effectively improved, and the false wake-up rate is reduced.

Description

technical field [0001] The invention relates to the field of speech processing, in particular to a method and system for adjusting a wake-up word preset reliability threshold. Background technique [0002] Speech recognition technology has made remarkable progress in recent years, and this technology has entered various fields such as industry, home appliances, and smart homes. Voice wake-up is a form of voice recognition technology. It does not directly contact the hardware device, and the device can be woken up and running by voice. Voice wake-up is to allow devices (smart speakers, mobile phones, toys, home appliances, etc.) to detect the user's voice (set voice commands, that is, wake-up words) even in the sleep or lock screen state, so that the device in the sleep state can directly Enter the state of waiting for instructions, and start the first step of voice interaction. In general, most devices rely on physical buttons to wake up or run the device. However, this i...
