Good Try

The main problem with this is that America has so many different accents, for example I live in Texas and my uncle lives in Maine, both in the US, however ive talked to germans and brits whos accents are more similar.

Also, the girl on the app talks strange for anywere really. She sounds like she is shy or something. Im sure its just because its always more difficult to speak when recording, but this recording just isnt a good representation.

She has the "Omg, like that is so five minutes ago!" voice.

Advice, try having different recordings, male and female for different areas.
