Re: [Bayonne-desktop] Re: GNOME "Telephony Application Programming Services" Proposed

[David Sugar <dyfet ostel com>]

Bill,

there was actually a couple of reasons and additional things brought up here 
which may have some relevance to gnome-speech and accessability efforts.  
While it has not been announced yet, we are also starting a seperate GNU 
package, GNU Alexandria, to develop e-government services for the blind.  
However, our interest in speech and accessibility, as it relates to GNU 
Bayonne, is in regards to supporting voice enabled devices and hosted 
services, rather than in directly solving desktop user accessibility issues.

Issues in supporting effective speech recognition and generation in Bayonne 
are ones that require support for many concurrent sessions simultaneously 
rather than one desktop user.  However, there is no reason why we should not 
make use of the same underlying speech or asr engines, api's, etc.  In 
particular, in Bayonne, we are already able to extend even limited concurrent 
speech generation resources through extensive use of smart caching which 
restricts the need for activily sythensizing voice for each and every 
instance of a caller.  

To date, I am only aware of several tts systems that potentially may be freely 
licensed; embrola, which I had never used, festival, which has license 
confusion and conflict right from the start (it has multiple licenses and 
parts of such as the "Edinburg speech tools" that it uses, are under a 
non-comm license, and many voices are proprietary licenses), and flite, which 
is under a BSD-like license, but has very limited voices.  Other things, like 
rsynth, are probably not all that usable in a practical sense though I 
suppose individual users can be "trained" to understand it's generated speech 
:).  What are the gnome speech people working with?
