九州電力 KYUSHU ELECTRIC POWER enters the smart speaker (like Amazon
Echo) market with a service named QUUN.  The standard voice that
it uses will be by 雨宮天 AMAMIYA sora.  You can have her read the news
to you or talk with her, and with additional hardware have her do home
automation (sensor readings, control your home appliances) and home
security (security alarms, tie-up service with SECOM) , etc.

Not sure if it is limited to Kyushu area.
They also mentioned there will be more voices to choose from later.
