I am a new owner of the Voice Preview device, but I cannot get it to recognise me saying “Hey Jarvis”. The other two wake words work fine, but I can’t get Hey Jarvis to work.
Are the wake words affected by the locale? I use German language so I don’t know how I am expected to pronounce Jarvis, although Mycroft works fine when pronounced English.
I speak English (with a New Zealand accent) and I too cannot get Hey Jarvis to work.
Think Texas. You’re German so this should make sense.
The J is Dsch… Like Dschungel
Ar is American not like arzt. Not ‘ah’ ‘ar’ and Don’t roll the r.
V like in Vater
Is like wissen
Jahr-wis. Where the vis is short and staccato.
Thanks for the advice, I will try different pronunciations and report back.
Interesting, have you tried different pronunciations too?
I pronounce hey like hay.
How else could I say it?
From Google:-
The word “hey” is pronounced with a short “e” sound, like in “hay”, and is often used as a casual greeting or to get someone’s attention
It’s less about the hey and more about the Jarvis 
“Hey Mycroft” works fine for me, pronounced what I think is English 
Same issue here in Germany. At least it usually does not work at the first attempt.
I’m German and I have this issue too. OK Nabu works best for me. But I don’t like it much.
It’s the same for me (also Germany), Hey Jarvis works sometimes, Okay Nabu works best.
Same here. Hope this is going to be improved in future releases in sense of it would accept more variations.
Would be also very cool if they would add a Jarvis like voice 
Fun story here from Austria (so sort of german ;-))
“Hey jarvis” works perfectly for me, but me wife gets refused 95% (although she doesnt speak it any different from me)
It’s a bit of a showstopper at the moment
