Tested Loquendo7 on the following versions of Primo :
Primo 2.4 18.104.22.1683722
Primo 2.4 22.214.171.1247029
Primo 2.0 126.96.36.199577 (I3)
Copied all the Loq7*.dll files to the root of primo, copied the tts_loq_7 folder to the root of primo, and copied the voice files (zip) to the content/voice folder.
Same thing happens on all of the above versions. When I choose the loquendo7 voice, there is no sound coming out (no test sound), and when I click on back button, it shows the previous voice chosen (Samantha, Nuance).
So in short, this set of loquendo7 TTS does not work on the above versions of primo.
My device is a generic GPS, with MTK3351 CPU, windows CE 5.0 operating system.
