Where exactly should I install espeak-ng? I will tell you about the project through the virtual environment.

[WhiteTeaDragon]

It doesn't matter where you install espeak-ng. You just have to set environmental variables properly in order to use it. For Linux I set those two:

import os

os.environ["PHONEMIZER_ESPEAK_LIBRARY"] = "/home/alsenderovich/lib/libespeak-ng.so"
os.environ["ESPEAK_DATA_PATH"] = "/home/alsenderovich/share/espeak-ng-data"

There are some discussions on github about this, you can find some advice for Windows users there: bootphon/phonemizer#117, rhasspy/piper#73, bootphon/phonemizer#44
