Pink-Trombone VS xVA-Synth

Too late to edit, but to any one who needs "convincing" of the flexibility of a formant synthesizer, you should 1) play with Pink Trombone[1], a Javascript formant synthesizer with a UI that lets you graphically manipulate a vocal tract, and 2) have a look at this programmable version of it[2]

Can I do it automatically without any audio/voice recordings at all, such as taking advantage of the pink trombone linguistics tool, (for which there is some source code)?

This is a source-available project, not an open source project. https://github.com/DanRuta/xVA-Synth/issues/7 pointed out in January of 2021 that the project has no license, implying that the creator reserves all rights except those they must waive to comply with GitHub’s terms of service. The project still has no license today.

Also, it’s not as easy to download the project binaries as the README makes it sound. The README links to https://github.com/DanRuta/xVA-Synth/releases, but no releases have been published. The README also says to “download the app from the Nexus websites”, but that doesn’t seem possible either. For one thing, the README mentions “the nexus.com website” further down, but https://nexus.com/ is unrelated – they actually mean https://www.nexusmods.com/. Even on Nexus Mods, searching for “xva synth” brings up results like “xVASynth 2 - SKVA Synth”, which sound like specific voice models, not the app itself. The one place I was able to find the app for download was on Steam as a free app: https://store.steampowered.com/app/1765720/xVASynth_v2/.

Second, this was made by a new tool for bethesda games modding called xVA-Synth a tool that lets you synthesize the voices of many bethesda game characters. Unlike 15.ai, this tool allows for way more customizability in voice clips, allowing you adjust the pitch and lengh of individual letters, and adjust the tonation of each segment. I've only just started playin with the tool myself, and I'm super impressed. I'm really excited to see what comes of this, both for mods and shitposting.
