I assume they just used the VocaListener-ish plugin and probably didn't tweak what it automatically created due to time constraints.Hate to say it, but maybe the "explosive" quality indicates they're using one of her new appends? Wat said they were going for a less human (but more understandable, which may/may not be the case here) direction, IIRC. I don't know if the makers of this video would even have access to the as-yet-unreleased appends.
Maybe she just wasn't tuned ideally.
I have VocaLisener and have done many tests with it, when your voice frys or goes low/a bit growly (ideally the recording has to be very clear and high range in your throat, almost opera-ish, for results that match the human recording almost exactly), it gets confused and makes the Vocaloid low pitched and odd-sounding (loud burst of mechanical noise similar to a fax machine), which is what seems to be happening in this commercial. VocaListener also gets confused when the human sample sings too quickly (ie, not good for talking).
I think it is using her new Append, because that's what they've been using for her talkloid stuff and Wat said they wanted the vowels to be less strong, which is probably why the consonants sound overly loud.
I do not think that the Appends will sound bad, I just think that the plugin can not properly handle the nuances of talking (especially with the plugin being unable to handle low voices, which happens when you talk). Using a singing voice to make talking requires a lot of hard work for proper tuning. This just proves to me once again that the Cryptonloids need a proper talking voice.
