aquest doesn't have any qualms with distribution but it can't be defoko. ameya has said on twitter that only japnese aquestalk1-f1 can use the defoko or utane uta name

that being said, aquest has very strict terms regarding monetization. so long as this is a purely hobbyist project and it cannot be monetized or used to advertise, then you are free to use and distribute anything using aquestalk samples.
