follows. Please note that there is a wide variety of information
available on our website under "Speech Engine" pull-down menu. You
should also review Freeswitch section under "Soft-PBX" for free connector and
engine pricing information. Our website is: <a rel="nofollow" target="_blank" href="http://www.vestec.ca/">http://www.vestec.ca/</a></span><br><div><br></div><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;" lang="EN-GB">1) What languages
do you
support</span></font><br><br>We currently support American English and
working on major European and Asian language acoustic models as well.<br><br><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;" lang="EN-GB">2) What are your
recognition
stats per language?</span></font><br><br>Three points are worthy of note
here: <br><br>(a) we have rigorously benchmarked our recognition
accuracy against leading commercial engines in the market and can safely
say that we deliver among the highest recognition accuracy in the
industry; <br><br>(b) generally speaking, a native speaker can expect a
recognition accuracy - without "tuning" - in the 90% range while a
non-native speaker can expect a recognition accuracy - again, without
"tuning" - in the 80% range. Grammar "tuning" - for example, via
addition of custom pronunciations for difficult to recognize words -
generally improves recognition accuracy by an additional 5-10%; <br><br><span>(c)
in comparative testing against some of the leading commercial speech
engines, we scored an accuracy improvement of over 3%. See: <a rel="nofollow" target="_blank" href="http://www.vestec.ca/recog_acc">http://www.vestec.ca/recog_acc</a></span><br><br><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;" lang="EN-GB">3) What are the benefits
of
using this compared to Sphinx/Pocketsphinx?</span></font><br><br>There
are two fundamental advantages of using Vestec over Sphinx: <br><br>(a)
Vestec speech engine comes with a robust acoustic model while for Sphinx
you need to develop your own acoustic model. (Acoustic model is the
"ear drum" if you will that does the recognition). Now, development of a
high quality acoustic model is no mean feat, even if you have the
necessary tools. For starters you need high quality training data that
can cost tens of thousands of dollars. Next, you need highly specialized
knowledge in order to properly manipulate the various parameters of
training tools for optimal recognition quality. Finally, you need to be
fully prepared to undertake a trial-and-error process - sometimes
spanning 6-8 months - to achieve the desired recognition accuracy
results, with the right data and training tools. <br><br>(b) Unlike
Sphinx, Vestec speech engine supports industry standard
grammar writing format. This allows you to port your existing standard
grammars to the engine as well as make sure that your work is reusable.
Similarly, we provide a variety of useful grammar writing tools and
functions that are not available with Sphinx to make the developer's job
a lot easier.<br><br><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;" lang="EN-GB">4)
How does the (1)
installation of a license happen, (2) license check happen.</span></font><br><br>You
need to put the license files that you purchase from Vestec webstore
under a specific directory. The engine then takes care of the rest. The
license check is host based. In other words, every license is
bounded to one physical/virtual machine. You cannot buy one port license
and
expect to run the speech engine on several machines.<br><br><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;" lang="EN-GB"></span></font>

Does
the licensing server
support redundancy schemes? </span></font></p><br>We used to have a
redundancy scheme but recently disabled it in preparation for the
release of a new architecture. The redundancy scheme will be integrated
in the new architecture that will support MRCP. Please note that
software maintenance - covering patches and major upgrades - is free for
the first 12 months since date of license purchase. So, you will be
able to transition to the new architecture over next several months if
you were to purchase a license now.<br><br>Hope this helps.<br><br>Best
