Taya is designed for Japanese language only. He does not have phonemes for other languages. His voice data is written in Kana, so Western users must convert the filenames into Romaji first before using him. A feature in Taya is that he can both sound like a male or female, hence being illustrated as a hermaphrodite. Taya is shown to be able to sing both high and low, and can succeed in singing in both octaves decently, but sounds best in between Alto 2 and Tenor 1 tone(s). Even though Taya has a pleasant voice, the pronunciations are a bit difficult to understand without proper tweaking.
