You can extract the energy from the encoded frames, but knowing which 
energy to choose is another matter. Just taking the greatest energy will 
lead to rapid hoping amongst speakers. If you are more relaxed about 
switching speaker you will miss the start of voice spurts. The loudest 
might not even be the most relevant speaker.
