Sapi5 version of espeak ng


I was wondering if there is some progress for a sapi5 version of espeak ng?
The reason I am asking is because I would like to be able to use espeak with narrator on windows 10.
I tried downloading the sapi5 version from but narrator doesn't recognise espeak.
I guess the reason is because this particular version of espeak is 32 bit but my computer is 64 bit.
Is there a way which we can make narrator to see espeak as 64 bit instead?
