I guess i exhausted my research in here in finding a 100% local solution in playing MP3 file in my house. I tried TTS, but locally TTS sounds like the robot in space invaders. So I gave up the tts idea. Since I don’t have that many messages I want to use (may be 5 or 6) I thought to create the mp3 and store them on a raspberry pi.
The HU and the raspberry pi are on the same local network which is a different network than my normal wifi. This is to make sure they are never on internet. They talk just fine.
I do not use Sono or GH. I really really want to stick with the pi. I’m sure somewhere there are drivers for that. But where? I searched and searched.
Anyone can lead me to the right direction?
