Check which language "Speech Recognition Data, xxxxxx ASR" you want to install.
If you choose english only, now in the .System\ASR\ folder you have two files named "en_US.srd" and "en_GB.srd".
Now copy in .System\ASR\ folder, the rest of the "special for the 3490" files depending if you have Europe or North America CN.

For 3760-->3490, you don't delete anything because you didin't have any ASR folder in the device.

Thanks let me update and see if it works ...
Awesome now it works perfectly!
