Thanks for your report.

Starting from v0.2.8, the build process is automated with a GitHub Actions workflow. Everyone can inspect the software code and the workflow code to know how the released files are built from source. But it's also from v0.2.8 that the released ZIP files have much more flags on VirusTotal.

There are two files that are flagged the most:

1. SpeechSDKPatcher.exe (15 flags)

Check its source code here.

From its behavior, it does seem suspicious, because it modifies DLL files. But that is to make those DLLs compatible with older Windows systems, such as Windows 7. It's completely unused on Windows 10 and later.

But an older version of SpeechSDKPatcher.exe somehow got less flags, so it's not the behavior that was detected. More likely it accidentally matches some malware signatures.

2. TtsApplication.exe (6 flags)

Check its source code here.

It is only a TTS sample program for testing, and its code is based on a Microsoft's sample project.

No malware behavior - but again, 6 flags.

Not sure why those files are flagged, though...
