Singularity is one profile for all voicepacks, which also introduced the ability to have multiple voicepacks active at the same time, with each voice taking the role of certain roles on your ship. Just like the bridge of a certain space ship.

Just need to import the new profile, let it initialise (when it says "this profile can do stuff", click yes), restart voice attack.

There is no method to automate the importing of the profile although we are working towards the updating of other stuff though (fingers crossed, etc etc).
