Apparently, neither AHS nor Dreamtonics bothers giving an extensive documentation / manual for using VOICEPEAK without the GUI. For comparison, VOICEVOX doesn't do great but at least you can get a grip scavenging through what they have in the repo.

So, half of this is translation of the aforementioned Japanese blogs, the other half is what I found out by trying.

Basic usage

./voicepeak.exe [OPTION..]

Starting with ./voicepeak.exe -h: {{code|lang=pwsh| -s, --say Text Text to say
