Urgent help needed : translation of audio evidence

Hi,

A false 498a case has been lodged on me and I have some audio evidences to counter the same. However, they are in regional language.

What needs to be done so that the court can accept it as valid evidence ?

1. Transcribing the audio proof to documents ? Who is authorized to do so , and where can I find them in Hyderabad ?

2. Translating the audio proof to English recordings? Again, where can I find some one to do the same in Hyderabad ?

thanks

Siva
