"OK Google" to unlock phone not working

[anon(10411243)]

I've recently discovered this cool feature of unlocking the phone by just saying "OK Google" but it doesn't work.

I set up everything and turned on the Voice Match option but it doesn't unlock. I tried to clear the cache and I tried to retrain the voice options multiple times.

I have a Huawei P8 Lite 2017 please help me out!
