Tmall Elf doesn't have the function of opening custom wake-up words, so Tmall Elf can't change the wake-up, but it can change the timbre. Click the bound Tmall Elf to enter the device details page, click the role supermarket, and select the tone you want to use.
At this stage, Tmall Wizard only supports modifying the name, and does not support custom wake-up words. At present, Tmall Elf has only two wake-up words, Tmall Elf, hello Tmall.
