A few months ago I uploaded a document proposing a new English UTAU recording script with detailed specifications. As an attempt to basically replicate a unit-selection based speech synthesizer in UTAU, the new standard was named Arpasing. Thanks to a few users who recorded the very first Arpasing voicebanks in spite of the lack of clear instructions, we're now able to further explore the uncharted land with Moresampler 0.8.0's built-in support for Arapsing oto generation. Here I'm launching another tool, and this time for actually creating USTs with Arpasing.
Please keep in mind that Arpasing is an experiment, and we don't yet know if it's going to work well, until more efforts are made to revise the tools & voicebanks.
