Mp3 file converter with language detection!

Avg Bid (USD)
Project Budget (USD)
$30 - $500

Project Description:
I have some mp3 files in which short sentences in German, English and Japanese are in this order.
(You can check a file on
and the sex of speaker will change)

Would you make a converter written in Java that can get rid of Japanese sentences?
I think it should detect languages because the length differs from sentence to sentence.

With this converter program (CLI maybe), we should be able to convert like below.
[German, English, Japanese] x N sentences -> [German, English] x N sentences

If you cannot catch the image nicely, please let me know!
