^Not 100% true, there are exceptions to this and you nee to read the agreement with any Vocaloid as some like the CFM ones or IA don't have a standard agreement.

For some vocaloids, you can use the voice but can't name or use the character, others you can. Luckily the majority of vocaloids by the 3rd party studios share the same set of rules among their studios vocals, so all Internet co ones share the same, all ah software, etc. There have been exceptions like Iroha, but Iroha has had that lifted.
