For your reference, here are the reasons for failing to wake voice assistant up quickly again:
1. When you cancel the voice assistant interface, the voice assistant does not completely exit or shut down. In this way, when the voice assistant is in a “half-off” state, it will ignore subsequent wake-up commands. It takes some time for it to completely exit and be ready to receive wake-up commands again after you manually cancel it;
2. Voice assistants will have a short “cooling time” mechanism to prevent repeated wake-ups in a short period of time. After you cancel the voice assistant, it takes some time for it to wake up again and process commands. The length of this cool-down period varies depending on different devices and operating systems.
Does it help?
