ayanami_v4_500st is a Japanese voice model that was created to perform songs. For her training, most of the lines from the original series were used, as well as a couple of songs performed by seiyuu Ayanami. As you might guess, it took me 4 attempts to take into account all my previous mistakes and create the best voice model with the Japanese voice of Ayanami (so far). The voice model was used mainly in changing the vocals of the songs, although it also copes with the usual dialogues acceptable.
