LumenVox is committed to improving speech recognition applications, and part of that process is to help educate the next generation of speech designers and developers. That's why we offer free software and resources to students and faculty who wish to use our software for educational purposes.

What You Get

The LumenVox Speech Engine is a speaker-independent automatic speech recognizer, capable of performing speech recognition on a variety of audio types. It is grammar based, meaning it is not suitable for dictation, hotword spotting, or audiomining.

It was designed primarily for use in telephone interactive voice response (IVR) applications, though it can be used for many other tasks, particularly where user speech can be broken into short, discrete utterances. Good candidates include applications such as command and control applications, where users speak a word or short phrase to control an application.

The Speech Engine is particularly well suited for academic use as it provides full-featured C and C++ API's for programmers, allowing them to have very fine control over the recognition process. Support for Media Resource Control Protocol v1 and MRCPv2 is also available for developers working in telephony environments that wish to use those protocols.

LumenVox supports open standards such as the Speech Recognition Grammar Specification (SRGS) and Semantic Interpretation for Speech Recognition (SISR). Though the Speech Engine is not an application server and thus cannot run applications, it is fully compatible with the VoiceXML standard. Support for these open standards makes it easy to compare our products with other speech recognition software.

LumenVox software runs on both Windows and Linux (Linux binaries are available for select versions of Red Hat Enterprise Linux, CentOS, Fedora Core, and Debian).

You can learn a lot more about the product by browsing our help files, watching our online training videos, or reading through our extensive resources section.

If you are a faculty member or administrator and would like to make the LumenVox speech recognition software available to a large number of students, please use the form below to contact us for details.

What It Costs

Nothing. We really do want to help new developers get exposure to speech recognition. At LumenVox, we feel that the world has only seen the tip of the iceberg when it comes to using speech recognition, and we want to see what the academic community can do with the software.

We do require that if you talk about your research or project anywhere publicly, you mention LumenVox and provide a link back to our Web site where possible. So, depending on the project and nature of publication, something like:

LumenVox: high-quality, free
<a href="http://www.lumenvox.com">
speech recognition software</a> for academic users.

or

This project is powered by LumenVox <a href="http://www.lumenvox.com">speech recognition software</a>.

If you are submitting a paper for publication in a print journal where you can't include links, include a line like:

The LumenVox Speech Engine was used as part of this research.

If you end up publishing your research or putting together a really great application, we'd also like to hear about it.

If you build something you think other people might be interested in, we'd even be interested in posting some audio (or video, if you have it) of the application on our Web site.
