sd_ibmtts crashes

[Gilles Casse]

Hi Jose,

Please found below three URLs and a summary of how I understand the
filter mechanism. Of course, my description can be more or less
accurate, but  well, hope it helps.

The filter is a kind of plugin which converts text. If several filters
are loaded, they will work in cascade: the first filter manages the text
supplied to eciAddText, the second filter manages the text returned by
the first filter and so on.

I implemented such a filter recently for the punctuation in voxin and
met two main issues:

- AFAIK, the filter API is not included in the public ibmtts sdk project
at sourceforge. It could raise questions on its license.

- the plugin must be built using an old c++ toolchain. I used crosstool
and provide a script for patching and building it.


Here are three urls:
- ibmtts api documentation from wizzard software (Dynamic Filters):
http://www.wizzardsoftware.com/docs/tts.pdf

- sources of the punctuation filter (except the filter header file), and
scripts for building the toolchain:
http://soft.oralux.net/punc-filter/

- the ibmtts sdk public project
http://ibmtts-sdk.sourceforge.net/

Best regards
Gilles
