Speech to Text Support in OLPC

[satya komaragiri]

Hello,

Thank you very much. I did not know sphinx 3 is written in C till you
pointed that out.

I did some more searching following your reply on the Speech To Text
engines in the Open Source world I still find Julius a good choice to
go ahead with.

Julius is better suited for dictation purposes as compared to HTK
(which is not Open Source anyway) and Sphinx [1] (the major
consideration as I believe we will need that application a lot). Also,
a comparison by an open source project Simon[2] suggests that Julius
is better than Sphinx in terms of various factors [3].

More or less this conclusion was based on exisiting research. Our
actual experience on XO is subject to actual implementation and
tryouts. But so far Julius has a better weight-age.
As another plus, Simon uses Julius (and QT) and is meant for the
Physically challenged children. It might serve as a nice reference.
Julius also supports DBUS.

The language model can be obtained from VoxForge and can be developed
over time as a side task too.

Kind Regards
Satya
