Title:
ARRIVAL REMINDING METHOD AND DEVICE, TERMINAL, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/115232
Kind Code:
A1
Abstract:
An arrival reminding method and device, a terminal, and a storage medium, relating to the field of artificial intelligence. The arrival reminding method comprises: in the case of a public transport means, collecting ambient sound by means of a microphone (201); performing time-frequency domain feature extraction on audio data corresponding to the ambient sound to obtain a time-frequency domain feature matrix (202); inputting the time-frequency domain feature matrix into a sound identification model to obtain a target alarm bell sound identification result output by the sound identification model (203); when it is identified that the ambient sound comprises target alarm bell sound, updating the number of traveled stations (204); and when the number of traveled stations reaches a target number of stations, performing arrival reminding (205). Ambient sound is collected in real time, the number of traveled stations is updated when target alarm bell sound is identified, and arrival reminding is performed when the number of traveled stations reaches a target number of stations; the terminal performs time-frequency domain feature extraction on the ambient sound, and inputs the obtained time-frequency domain feature matrix into the sound identification model, thereby improving accuracy and effectiveness of arrival reminding.
