Is this the real voice of male/female in the examples of voiceover or it is some bot / software converting the voice into male or female ?
By listening the above audio, the voice does not look natural.
It sounds like a computer, not like a human. That's too bad, because this could be a good service. I've seen many promotional Youtube videos that use a digitally created voice-over. If you could provide a human voice, you may find more buyers.
