A VOCALOID is a voice synthesizer. Any character that runs on the VOCALOID engine is a VOCALOID. It's a franchise and brand owned by Yamaha.

So not any "virtual idol" is a VOCALOID. "Virtual idol" is more of an umbrella term and can be a character who runs on a synthesizer or not. Kizuna Ai is a virtual idol for example because she is an virtual character, but is voiced by a live person.

So every VOCALOID can be considered a "virtual idol", but not every virtual idol is a VOCALOID.

Does that make any sense?
