Since the last public release, 1.1.1, January 1999, there have been
a number of enhancements to the library system
- Free licence
To make the system more useful for more people and place
it properly in the free software community the system is now free
for both commercial and non-commercial use alike.
- Utterance consolidation
A number of tidy ups have been performed on the
EST_Utterance and related classes. This makes
the interface cleaner and should have littel affect on existsing code.
- Generalization of Features
Any new object can become a feature value after simple registration
of the object through a provided macro. We also make much
more use of this.
- SIOD tidy up
Scheme is no longer "in one defun" but "in one directory". The
system was split out into separate files. New objects are now
held as EST_Val and it is easier to add new
objects to the system.
- C++ class documentation
We now include documentation on a per class basis using the
DOC++ system and docbook for more general
descriptions and examples. This has improved the coverage and quality
of low level documentation for all classes in the system.
- Tilt Analysis/Resynthesis
For intonation analysis the tilt code has been completely rewritten.
