Japanese vocals at their quickest take 2-4 months to produce, 6 for a half decent one at least.

English vocals take about 4-6 months at their quickest and 8-1 year for a decent vocal.

There about a dozen companies at this point, the ones who are doing regular releases are;
 * Crypton Future Media
 * Internet co
 * i-Style
 * PowerFX
 * Zero-G
 * AH software
 * Bplats
 * Voctro Labs

Thats 8 companies regularly churning out Vocals, so you might get at least 8 vocals if each produces 1 a year (doesn't tend to happen). Theres been several one off vocals too from other companies like Piko or IA.
