I have a player who decided to play a droid, and when I was going through the rules to create custom droids, I couldn't find anywhere what automatic languages they have.
The best aproximations to rules I found were in the Communication subsection within the Accesories section (Core Rulebook, page 193).
All droids are capable of emitting the sounds necessary to speak Binary, a language used by droid an computers [...].
Vocabulator: The droid is equipped with a speaker that enables it to emulate speech, rather than simply spout machine code. This device is standard if the droid has ability to speak any language other than binary.
Is a custom PC droid able to speak (or, at least, understand) Basic by default, hence owning vocabulator by default too, or do it needs to pay for it?
Is there any place in the rules where it's described which are the automatic languages for a droid?
