The Microsoft online voices work again

• In 2026 Microsoft's classic voice server started refusing connections (HTTP 403) for many users, for every app built on edge-tts (edge-tts #490), and FluentVoice fell back to offline voices.
• When the classic server refuses, FluentVoice now switches by itself to Microsoft's newer server for the same voices and keeps using it for the session. All 80 online voices were tested on it. Nothing to set up.

Every language, the right voice

• Chinese, Japanese and Korean text with English names is detected correctly. A product name like "FluentVoice Pro" in a Chinese sentence used to make it count as English.
• Languages FluentVoice has no voices of its own for (Dutch, Polish, Turkish, Swedish, Vietnamese, Finnish, Greek and more) are read by a Multilingual voice, and Settings and notifications show the real language name ("Lang: Dutch (Multilingual voice)") instead of "English".

New: Components & sources (Settings → About & Developer)

• Test providers: a live health check of the online voices, offline HD voices, Windows voices, tray and hotkeys, audio output and the last 24 hours of errors. Each problem comes with a plain-language diagnosis, what to do, and the alternatives (no internet vs. a firewall vs. an outage on Microsoft's side; a hotkey owned by another app; no offline voice for your language).
• Verify / repair offline voices: checks every downloaded Piper / Kokoro file against its pinned SHA-256 and offers to download damaged ones again, only from the official sources.
• Components: the version, licence and source of each component, and Open log folder.
