Portable executable (Win)

Syllavox v0.1.0

Syllavox v0.1.0 is the first public MVP release: a portable Windows desktop
application for reading text aloud locally with Piper voices.

What is included

• Portable Windows application; extract the ZIP and run Syllavox.exe.
• Local Piper text-to-speech and WAV playback.
• Voice discovery and explicit installation from the in-app catalog.
• Loading, unloading, and deletion of installed voice files.
• Language-grouped voice selection shared by the window, hotkey, browser
  extension, and local API.
• Clipboard hotkey, pause/resume, stop, playback interruption, and explicit
  WAV export.
• Chrome and Edge browser extensions, with experimental unsigned Firefox
  support.
• Local FastAPI API at 127.0.0.1:8765.
• Piper compatibility diagnostics and local temporary-audio cleanup.

First use

1. Download Syllavox-portable.zip from the GitHub release.
2. Extract it to a folder and run Syllavox.exe.
3. Open the window from the system tray.
4. Choose Find more voices..., install a voice, select it, and speak a
   short test sentence.

Voice models are intentionally not bundled. An internet connection is needed
to browse and download a voice; speech synthesis itself runs locally after the
voice is installed. Some Chinese voices also download Piper's shared g2pW
resource on first use.

Important limitations

• Windows is the only supported platform in this release.
• There is no conventional installer or automatic updater yet.
• Firefox support is experimental and requires temporary extension loading.
• Some Piper voices have language-specific model or phonemization problems.
  In particular, some Hebrew voices currently fail to load with
  hebrew is not a valid phoneme type.
• Voice pronunciation and text-formatting behavior remain under active
  compatibility investigation.

Privacy and licensing

Syllavox performs synthesis locally and does not use a cloud TTS service.
Downloaded voices, settings, logs, and runtime audio are stored under
%LOCALAPPDATA%\Syllavox\. Voice models are separate works with their own
model-card and dataset terms; they are not covered by Syllavox's MIT license.
