AI Technical Summary
Technical Problem
Existing voice wake-up technology is sensitive to changes in the speaker's speaking speed, which leads to a decrease in wake-up accuracy, especially with frequent false wake-ups when the speaking speed is fast or slow.
Method used
By classifying Chinese characters into categories with different levels of pronunciation clarity, the search order for the core wake-up character is determined by the characteristics of the vowel nucleus. Within the wake-up word search range, the wake-up is triggered when the score of each character reaches a preset threshold.
Benefits of technology
It improves the accuracy of voice wake-up, reduces false wake-ups, and enhances the user experience.

Abstract
Embodiments of the present application provide a Chinese speech wake-up method, system, electronic device and storage medium. The method comprises: dividing the characters in the Chinese speech into different categories of pronunciation clarity by using the rime; determining the category search order of the wake-up core characters in the Chinese speech based on the category of pronunciation clarity of each character in the wake-up word of the intelligent device; determining at least one wake-up core character in the Chinese speech through the category search order; determining the wake-up word search interval in the Chinese speech according to the at least one wake-up core character; and performing speech wake-up when the score of each character in the wake-up word in the wake-up word search interval reaches a preset threshold. Embodiments of the present application start from the composition of Chinese pinyin, consider the pronunciation characteristics of the initial and final consonants, select the final consonant with loud pronunciation, and then take it as the reference point to find other characters. Thus, the influence of speech speed on the wake-up accuracy is solved, the accuracy of wake-up is ensured, and the experience of users using Chinese speech wake-up is improved.
