Re: [AUDITORY] PESQ and other speech quality algorithms

[Graham Paul Rousell <gr@xxxxxxxxxx>]

Dear Nicolas,

Thank you for your very detailed and precise response.  My apologies for 
not being able to come in earlier on these posts.



Yes, in summary, publication within a book of previously copyrighted 
material is itself an infringement of copyright, and then the fact that 
patents may be incorporated within that is further infringement. If the 
code within Loizou's Speech Enhancement book does not use the same code or 
patents then this might not be an infringement (other than trade name).  I 
would hope so since to the best of our knowledge Mathworks don't have a 
license agreement to be able to publish or distribute PESQ. 

Regardless of source or application it is everyone's liability to care 
about third parties' intellectual property rights, whether they are 
patents, copyrights or trademarks.



There are various examples that could be considered, but probably that of 
pharmaceutical R&D is most analogous here. Papers are published all the 
time of copyrighted and patented material, but it is very well understood 
that those developments are strongly defended if there is ever indication 
of infringement.



Once again, I will say that the offer is there, to use a fully conformant 
time limited version of PESQ, for qualified academic purposes, on 
application from OPTICOM. 



Best regards,



Graham
