I'm having trouble getting speech produced on a 2024 MacBook Pro with a M4 chip.

I went through their troubleshooting list and they read me file and everything's OK except that the bin sub directory espeak-ng-data/ is missing. Insread, there is a bin/bin subfolder that contains espeak, espeak-ng speak, and speak-ng. Is this an outdated folder name in the README.md?

I get the following error messages with two attempts:

I tried the suggested configuration without success.
I'm now using the following configuration suggested to me by Claude 3.7 Sonnet, also without success.

(use-package piper-mode
:straight (piper-mode
:type git
:host github
:repo "snowy-0wl/piper-mode"
:files ("*.el" "bin" "models" "setup-piper.sh"))
:init
;; Enable debug logging - moved to :init
(setq piper-debug t)
;; Adjust process timeout (default: 30 seconds) - moved to :init
(setq piper-process-timeout 60)
:config
;; Set the voice model AFTER the package is loaded
(setq piper-voice-model (expand-file-name "models/en_US-joe-medium.onnx"
(file-name-directory (locate-library "piper-mode"))))

;; Run setup script if model doesn't exist
(when (not (file-exists-p piper-voice-model))
(let ((default-directory (file-name-directory (locate-library "piper-mode"))))
(shell-command "chmod +x setup-piper.sh")
(shell-command "./setup-piper.sh .")))
(piper-mode))
