John, 

Most of the answers to your questions can be found on the ITU website. 

http://www.itu.int/rec/T-REC-P/en

http://www.itu.int/ITU-T/studygroups/com12/index.asp

Other good references are companies who actually sell software based on these recommendations 
such as www.opticom.de, www.psytechnics.com (white papers). 

I hope this helps.

List,

Looking for some help in relation to information on ITU speech quality assessment standards.

1. Is P.563 and P.SEAM the same standard? (In other words P.SEAM is just another name for P.563?)

2. When did P.563 become a standrad, was it 2004 or 2006?

3. Apart from E-Model, PESQ and P.SEAM are there any other recent ITU standards on this area?

4. Are there any plans for new ones?

Thanks for help with this information. Some confusing information given out there so any info is appreciated.

Thanks......John
