Overview

This page contains downloads and information for the Delta-style General Purpose English List, made as an UTAU English recording list for Japanese people.

Unlike Japanese, which has CV, rentan, CVVC, VCV, etc. an English voicebank must be CVVC.

Although Japanese CVVC is much smaller than Japanese VCV, English CVVC can be up to 10 times larger than Japanese VCV, which is impractical.

Given that, these 8 versions range from the most unlimited no-compromises list to the most limited and condensed list.

List Principles

Each list’s properties and recording amount comparison are in the following table:

Number	Similarly sized Japanese reclist	Recording time	Notes
0	full VCV with CCV, etc.	10 hours	Theoretical list, not practical
1	VCV	6 hours
2	mimirobo-style VCV	3 hours	Recommended
3	Mixed VCV and CVVC	2 hours 30 minutes
4	eve-style CVVC	2 hours
5	Delta-style/Tsubasa-style CVVC	1 hour 30 minutes	Recommended
6	CV	1 hour 30 minutes	Smallest
7	CV	1 hour	Smallest, quick to record, for advanced users

Note: “Similarly sized Japanese reclist” is only an example. Every version of the list is actually CVVC.
Note: If you take into account the amount of time you spend rerecording samples, version 5’s length is the closest to Japanese VCV.

General principles

• CVVC-based voicebanks
• Assuming the pronunciation of Japanese people who are unfamiliar with English, similar-sounding vowels are grouped together.
