This looks like it was previously known as Vocodes, made by echelon who is here on HN: https://news.ycombinator.com/item?id=23965787 https://news.ycombinator.com/item?id=23965787 The code repos used are listed in their credits section, and it looks like a mixture of (customised?) Tacotron2, Glow-TTS, HifGan, and others. Videos are generated using Wav2Lip. Text-To-Speech (TTS) has improved greatly over the past several years, but there's still a lot of metallic sounds in "pure" TTS implementations. I've started exploring voice style conversion, otherwise known as "voice cloning", and there are some interesting repos out there with decent results. These work differently from TTS, in that you don't type out the text to be spoken, but rather pass in an audio file of what you want the cloned speaker to say, and the system outputs an audio file with the same sounds (words, intonation) but with a different speaker identity. This may be easier to get the right cadence and emotion in the generated audio, as text doesn't capture proper emotion and intonation. I suspect game character audio will use more of voice-style conversion instead of pure TTS simply to get the right emotional cadence of the lines being delivered.
