Hi all
Having far more trouble than expected trying to install anything to simply play anything out the 3.5mm socket on a pi4 (it will take triggers from a remote MQTT server & just be a trigger to audio converter).
I have tried about 4/5 modules via the palette manager and all seem to fail to install.
Running OS 2020-02-13-raspbian-buster-full
Node Red 1.0.5
Ultimately I would love to use TTS, but these all seem to be browser based. Thats for another day !
The simplest on Pi (3 at least) is to use an exec node with espeak - which you can sudo apt install espeak
(there are some bugs in espeak with various workarounds so you may need to google if it doesn't just work)
@dceejay thanks very much for that, OK not used an EXEC node before, I see how that works.
The voice is OK but not the best tbh I have tried using some of the other voices too.
IIs there a solution where I could use Watson AI to generate a better voice & play that to the speaker ?
Thanks
