RuntimeError: espeak not installed on your system

[valentinweyer]

Environment

• macOS Sonoma 14.3.1
• M1 Max 64GB

Issue Description I am attempting to run the inference_tts.ipynb notebook on an Apple Silicon Mac. As part of adapting the code for Apple Silicon, I replaced CUDA references with MPS (or CPU where MPS isn't an option). However, I encountered a runtime error related to espeak not being recognized by the system despite being installed.

Steps taken

1. Installed espeak via Homebrew using brew install espeak.
2. Confirmed espeak installation with espeak --version, which outputs 'eSpeak NG text-to-speech: 1.51.1'
3. Ran the inference_tts.ipynb notebook after making necessary modifications for MPS compatibility.
4. Encountered the RuntimeError: espeak not installed on your system upon executing Cell 4.

Behavior Despite espeak being installed (confirmed via command line), a RuntimeError is thrown indicating that espeak is not installed on the system.

Troubleshooting Steps Taken

• Verified that espeak is accessible via the command line and shows the installed version.
• Attempted to reinstall espeak through Homebrew.
• Checked the system's PATH to ensure it includes the directory where espeak is installed.

Full output with error

RuntimeError: espeak not installed on your system

I would also really like to do it without e.g. Docker, because I want to try to use MPS for the Apple Silicon GPU.

Would appreciate any guidance on resolving this issue so that espeak is correctly recognized by the system and the notebook can run as intended.

Adding this solved it:

from phonemizer.backend.espeak.wrapper import EspeakWrapper
_ESPEAK_LIBRARY = '/opt/homebrew/Cellar/espeak/1.48.04_1/lib/libespeak.1.1.48.dylib'.  #use the Path to the library.
EspeakWrapper.set_library(_ESPEAK_LIBRARY)

Thanks.

I am attempting to use phonemizer with espeak. I set the library path as above after installing phonemizer and espeak etc. I have tried all tricks but keep getting the following error despite following the thread
