8results about How to "Improve search speed" patented technology

The application discloses a multimedia resource search method, related device and vehicle, and relates to the field of human-computer interaction. When a user performs resource search, it is first judged whether there is a running multimedia application. When it is judged that there is a running multimedia application, it is further judged whether to perform search in the multimedia application according to the obtained search voice content. When it is judged that search is performed in the multimedia application, the multimedia application is directly called to perform in-application search according to the search voice content, so that the searched multimedia resource is more consistent with the user's expectation, the user's use experience is improved, the search speed is improved due to the direct search in the application, and the user's use experience is further improved. When it is judged that there is no running multimedia application, search can be performed in a media resource library outside the multimedia application, so that the user's resource search demand is met, and the user experience is ensured.
