I am native Czech speaker. So this is not going to be problem for me.
Because I am very good in music mixing & mastering, I can record this on the Macbook Pro, which is going to be better quality than on the phone for sure. I can even do the editing after that so it is going to be even higher quality.
But I can't do it for that price, as 1050 sentences is a lot.
If you also want to edit the recorded sentences, price would be negotiable.
Many thanks.
