The text on the video says ONE CeVIO AI Song voice is α版 (alpha version).
The song is catchy and reminds me of an anime OP.
At 13:20 and on, they say:
This month and next month, there will be lots of news. New CevIO software (probably their song banks, I guess), live concert, crowdfund.
They say they forgot to talk about HIPPI, but say she is waiting and they plan to have things like a special ARIA station video to talk about HIPPI in particular.
They do these ARIA Station things at the end of the month, so we'll have to wait a while for next month's.
