FluentVoice Pro 1.6.4: online voices back on Microsoft's original server
FluentVoice Pro 1.6.4 is out: the Microsoft online voices are back on their original server.
In October 2026 Microsoft's classic voice server started refusing connections (HTTP 403) for every app built on edge-tts (edge-tts #490). FluentVoice 1.6.3 worked around that by switching to Microsoft's newer server. Upstream edge-tts 7.3.0 / 7.3.1 fixed the outage, so 1.6.4 requires edge-tts 7.3.1 and reads from the classic server again. The 1.6.3 failover stays as a safety net.
Also new: if Microsoft briefly limits requests after many readings (HTTP 429), Test providers now says so in plain words and suggests waiting a minute or using an offline voice.
