Espeak NG on Windows & Mac
I had some trouble getting it up running on windows 11.
I got it working by installing the espeak-ng from the github (1.51 64x.msi version)
And adding this to the python code:
import os
Set the environment variables
os.environ["PHONEMIZER_ESPEAK_LIBRARY"] = r"C:\Program Files\eSpeak NG\libespeak-ng.dll"
os.environ["PHONEMIZER_ESPEAK_PATH"] = r"C:\Program Files\eSpeak NG\espeak-ng.exe"
Verify that they are set
print("PHONEMIZER_ESPEAK_LIBRARY:", os.environ.get("PHONEMIZER_ESPEAK_LIBRARY"))
print("PHONEMIZER_ESPEAK_PATH:", os.environ.get("PHONEMIZER_ESPEAK_PATH"))
Hope it helps if anyone else gets stuck on the same problem.
Thanks, something similar was posted on Discord a couple days ago, but it should also be here for visibility.
I think you can also use EspeakWrapper.set_library, but I do not have access to a Windows machine so I cannot confirm.
For Mac users:
At the top of kokoro.py (before import phonemizer) put:
from phonemizer.backend.espeak.wrapper import EspeakWrapper
EspeakWrapper.set_library('/opt/homebrew/Cellar/espeak-ng/1.52.0/lib/libespeak-ng.1.dylib')
or whatever the correct path is for your system.
(Anyone can open a PR if you know how to detect & do this automatically for Windows and/or Mac.)

it helped to override lack of espeak installation but now i get AttributeError: 'Munch' object has no attribute 'to'
Using scoop
scoop install espeak-ng
home = pathlib.Path.home()
os.environ["PHONEMIZER_ESPEAK_LIBRARY"] = str(
home / "scoop/apps/espeak-ng/current/eSpeak NG/libespeak-ng.dll"
)
os.environ["PHONEMIZER_ESPEAK_PATH"] = str(
home / "scoop/apps/espeak-ng/current/eSpeak NG/espeak-ng.exe"
)
os.environ["ESPEAK_DATA_PATH"] = str(
home / "scoop/apps/espeak-ng/current/eSpeak NG/espeak-ng-data"
)
