There are some models available [2], built from databases which are not themselves redistributable. There are also a number of model-building tools available [3-5], which may be sufficient for small command-and-control tasks. But you are right. For general-purpose voice recognition, we don't have the data we need. Still, I think it may be worth putting the software in place so that those who wish to purchase licenses to commercial data have everything else they need, and to encourage the production of better quality free data [6]. </pre> </blockquote> I also think that making the software available has a considerable effect in encouraging people to generate free data. When speech recognition software is available, community will be encouraged to generate data to make it more robust. But people will not generate required data when they can use it already! I have not much free time, but I'm interested to help you in this direction if I can. :) Good luck, Hedayat <blockquote style="border-left: 2px solid rgb(16, 16, 255); color: navy; background-color: rgb(245, 245, 245); padding-left: 15px;" cite="mid:870180fe0903251946s59ab8e56q31e58f28dbc36f23@mail.gmail.com" type="cite"> <pre wrap="">References: [1] <a class="moz-txt-link-freetext" href="http://www.speech.cs.cmu.edu/databases/">http://www.speech.cs.cmu.edu/databases/</a> [2] <a class="moz-txt-link-freetext" href="http://www.speech.cs.cmu.edu/sphinx/models/">http://www.speech.cs.cmu.edu/sphinx/models/</a> [3] <a class="moz-txt-link-freetext" href="http://www.speech.sri.com/projects/srilm/">http://www.speech.sri.com/projects/srilm/</a> [4] <a class="moz-txt-link-freetext" href="http://cmusphinx.sourceforge.net/html/download.php#SphinxTrain">http://cmusphinx.sourceforge.net/html/download.php#SphinxTrain</a> [5] <a class="moz-txt-link-freetext" href="http://cmusphinx.sourceforge.net/html/download.php/#cmulclmtk">http://cmusphinx.sourceforge.net/html/download.php/#cmulclmtk</a> [6] <a class="moz-txt-link-freetext" href="http://www.voxforge.org/">http://www.voxforge.org/</a> </pre> </blockquote> </body> </html>
