Is your feature request related to a problem? Please describe.
I have a Music Bot that checks if the message.author is an vc. If not it send an error

Describe the solution you'd like
Make a function so that corde joins a vc with e.g. the id

Describe alternatives you've considered
there are no

@kaaax0815 the bot check if the message.author is in a voice channel. That is it?
If so, right after release the function for issue #722, I will work on this one. Sorry about the delay, college is taking more of my time than I wish

@lucasgmagalhaes Take your time for school it important. But thanks for taking your time

@lucasgmagalhaes Cool would also be, to check if the bot (not corde) joins a vc or the same as corde and if it speaks.
Because I have many dynamic responses regex test or something like that would be nice to have
