[Q] ok google while recording video

Just wondering if anyone is able to activate ok google while recording video. Only reason this is an issue for myself is I run sygic and the dashcam while driving, this recording of course also means I am driving, and ideally I like to be able to have hands free options since getting a ticket and demerits would suck.

Does anyone have a potential work around or am I the only person experiencing this?
Any help would be appreciated ladies and gents of XDA.
