User blog comment:Animekyusie/Should there be Vocaloids other than Japanese, Chinese, Engish and Spainish/@comment-53539-20171010180846

Each vocaloid is made from a dev kit, the kit is only developed if there is a company who would use it.

Take note that while Yamaha have a Spanish kit, there currently isn't any Spanish vocaloid being developed. This is what each new language faces... Out of 3 of the new V3 languages only 1 has taken off, Chinese. Korean is struggling and Spanish is... Just there.

There is a lot more to things and its difficult to determine what languages Yamaha will release next, but they do not do this for charity and they do it for profit. Companies generally get charged more if they exist outside of Japan because it counts as a export license. And if the language is as complex as English, then it takes a while to make and cost to make. So Vocaloid ends up being a low profit product. On top of it... It only rakes in a profit if it even meets a certain amount of unit sales.

At this stage of the game, Yamaha has more chance of producing language dev kits for vocaloids in languages like German, simply because the audience is bigger.

As Viper pointed out, you can produce a vocaloid in a language but the fans are not committed to buy it. The issue with why Luan and Lucia were so ill received were both were too close to Clara, producing a supposed lack of variety. On top of that, Spain Spanish is not as in demand, as though there are many Spanish fans they are not typically Spain Spanish ones and of 5 vocals that were going to be, all 5 had that accent.

Vocaloid is more or less in this situation where the fans demand more languages but Yamaha may never give that language. The guys who tried to do Alys tried to get Yamaha to produce a French Vocaloid, but Yamaha maybe will, but not produce one simply because people come to them with demands for it.
