Modern technology could quickly and easily determine if the two men in an audio clip conspiring to bring former PM Thaksin Shinawatra back to Thailand were actually Thaksin and Deputy Defence Minister Yuthasak Sasiprapha.

Besides the voices, listening to background noise can be a giveaway. Fake clips do not have the same background noise. However, it is harder to detect a voice modified to sound like a specific person.

The government turn to the National Police's Scientific Crime Detection Institute and the Justice Ministry's CIFS for forensic investigation.

The National Electronics and Computer Technology Center's equipment is 80% accurate in terms of voice manipulation analysis. They are now developing a program to check voice authenticity that is 100% correct.
