espeak-ng compatibility issue on M3 chip with Phonemizer

[kqkqgithub]

Description:

I encountered an architecture compatibility issue when using Phonemizer with espeak-ng on a Mac with an Apple Silicon (ARM64) chip. The error message suggests that the espeak-ng library is not compatible with the architecture.

Error Message:

# filePath: /phonemizer/backend/espeak/api.py
espeak: CDLL = ctypes.cdll.LoadLibrary(str(library))
Error: tried: '/opt/homebrew/Cellar/espeak-ng/1.52.0/bin/espeak-ng' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')), '/System/Volumes/Preboot/Cryptexes/OS/opt/homebrew/Cellar/espeak-ng/1.52.0/bin/espeak-ng' (no such file), '/opt/homebrew/Cellar/espeak-ng/1.52.0/bin/espeak-ng' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64'))

Environment:

• Operating System: macOS 15.0.1 (24A348)
• Mac Chip: Apple Silicon (Apple M3 Pro)
• Python Version: Python 3.10.16
• Phonemizer Version: phonemizer-3.3.0
• espeak Version: /opt/homebrew/bin/espeak: Mach-O 64-bit executable arm64
• espeak-ng Version: /opt/homebrew/bin/espeak-ng: Mach-O 64-bit executable arm64

Steps to Reproduce:

1. Install espeak-ng using Homebrew on Apple Silicon:

   brew install espeak-ng

2. Install Phonemizer using pip:

   pip install phonemizer

3. Run a simple phonemization script in Python:

   from phonemizer import phonemize
   result = phonemize("Hello world!", language='en-us')
   print(result)

Expected Behavior:

Phonemizer should correctly load the espeak-ng library and perform phonemization without architecture-related errors.

Actual Behavior:

The espeak-ng library fails to load due to incompatible architecture, requiring x86_64 but having arm64.

Additional Information:

The issue seems to stem from a mismatch in the architecture between espeak-ng and the expected binary format. Running Rosetta 2 for emulation may not be ideal for performance-critical applications.

Possible Workaround:

Any recommendations or workarounds for ensuring compatibility with Apple Silicon would be appreciated.
