The piper executable included in the piper_macos_aarch64.tar.gz package seems to be compiled for x86_64 architecture instead of arm64, contrary to what the package name suggests. This has caused compatibility issues on an Apple M2 MacBook Pro running MacOS, specifically with the dependency libespeak-ng.1.dylib expecting an x86_64 version.

Steps to Reproduce

1. Downloaded the piper_macos_aarch64.tar.gz package from [https://github.com/rhasspy/piper/releases/download/2023.11.14-2/piper_macos_aarch64.tar.gz].
2. Extracted the package and executed piper.
