I have installed Google Assistant on Raspberry Pi 3. My program has some output as fixed audio. Can I use Raspberry Pi 3 to speech it? The problem is that when using other programs to read, I have to turn off google assistant and turn on when finished speechding. Because they all use the same output device
You can send text queries to the Assistant, and you could theoretically send a query in the background of "Repeat after me X" and the Assistant will repeat it. That may work for static or simple text.
