The NIST SPeech HEader REsources (SPHERE) Package Version 2.6 Installation: $ aclocal && autoconf && automake $ ./configure $ make For a description of SPHERE, read the files, 'doc/sphere.rdm' and 'doc/sphere.doc'. UNIX-style man pages can be found in 'doc/man'. If you're linking the sphere library with code written for SPHERE version 2.0 or 2.1, the argument calls for sp_read_data and sp_write_data have changed. Section VI, "Linking to the SPHERE library" in the document "doc/sphere.doc" describe ways to use the old code without re-writing it.
