LumenVox Distributed Architecture

Though the LumenVox Speech Engine is commonly run on a single machine, it can also be run in a distributed manner, with multiple clients and servers working together. This allows it to function well in high-volume speech recognition solutions, as the computing demand can be split across multiple machines (this is known as load balancing, since the workload is balanced across several computers). It also enables users to set up redundancy: if one Speech Engine server goes down in a multi-server environment, clients can switch servers seamlessly. Learn More

Using speech recognition can be intimidating at first, even if you're a seasoned developer. It requires learning new interfaces, understanding new technology, even mastering new jargon.

But the LumenVox speech recognition software is so simple, we believe you can get your first speech application running in less than an hour. If you started installing our software at the same time you ordered a pizza, you could probably get speech recognition working before the pizza showed up.

So if you've been putting off building speech applications because you don't have the time, now is the time to try out LumenVox and see how quick it is.

The following links will take you to detailed instructions for installing the LumenVox speech recognition software and running a speech application, depending on how you plan to use speech recognition.

If you follow these instructions, you should be able to start controlling applications with speech by the time your lunch hour is finished.

And if you don't believe that it's this simple, each of the links includes a video demonstration ? you can watch (and time) us as we go through the entire process.
