Embodiment Construction

[0026] Attached below Figure 1-4 The technical solution will be further described with specific embodiments to help understand the content of the present invention.

[0027] Such as figure 1 As shown, a method for waking up a voice assistant with a headset without a low-power wake-up chip, which includes in-ear detection, opening detection, audio A circular buffer, audio B recording, and a wake-up judgment calculation unit.

[0028] The specific steps are: first perform the in-ear detection; start the opening detection and the audio A circular buffer at the same time after detecting the in-ear; when the user's opening is detected, start recording audio B and record audio A and audio B according to Timing is merged, and then transmitted to the wake-up judgment calculation unit, and the wake-up judgment calculation unit performs the wake-up judgment of the voice assistant on the combined audio A and audio B; when the voice assistant wake-up judgment condition is established, w...

Abstract

The invention discloses a method for awakening a voice assistant by an earphone without a low-power-consumption awakening chip. The method comprises an in-ear detection unit, an opening detection unit, an audio A circular caching unit, an audio B recording unit and an awakening judgment calculation unit. The method comprises the following specific steps: firstly, executing in-ear detection; starting the opening detection and the audio A circular cache at the same time after the in-ear detection is detected; when it is detected that the user opens the opening, starting to record audio frequency B, transmitting the audio frequency A and the audio frequency B to the awakening judgment calculation unit, and when the voice assistant awakening judgment condition is met, awakening the voice assistant; and when the voice assistant wake-up judgment condition is not satisfied, returning to the initial state to operate the ear detection algorithm. The method has the beneficial technical effects of saving space, increasing the design flexibility and reducing the cost.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a method for waking up a voice assistant by an earphone without a low power consumption waking chip. Background technique [0002] The function of true wireless Bluetooth headsets with intelligent voice assistants is convenient, easy to use, and intelligent, and has become more and more widely used in recent years. In order to enable users to wake up the voice assistant on the mobile phone by speaking into the headset without picking up the mobile phone, or manually waking up the headset or the mobile phone, some headset manufacturers choose to equip the headset with a low-power wake-up chip. [0003] In the solution equipped with a low-power wake-up chip, the main connection line is: the microphone on the headset—the low-power wake-up chip—the main computing unit. The microphone on the headset picks up the user's voice, and then uses the computing power of the low-power wake...
