Dear Sir/Mrs

My research field is speech enhancement and want to know about bandwidth
extension more.
If any one have comprehensive information about these methods please help me to
solve my problem about codebook method.

I can not convert my LSF's coefficients for narrow band speech to wideband
speech LSF's.

Regards.

Seyed Farid Mousavipour
