Automated Speech Recognition (ASR)

LumenVox designs, develops and deploys automated speech recognition software and solutions.

Through accurate speech recognition and powerful tools, our software helps hundreds of contact centers, platform providers, IVR developers, system integrators and IP–PBX vendors achieve their speech integration goals.

A speech engine or automatic speech recognizer (ASR) is the technology that allows you to interact with a computer by speaking to it. This is most often used in telephone systems, but can be applied to many other computer applications.

The real star of LumenVox is our Speech Engine. We've worked hard over the years to offer a speech recognition engine regarded as amongst the most accurate and reliable in the industry.

The LumenVox Speech Engine takes in audio guided by a list of words to be recognized called the grammar. Only the words in the grammar are considered during the conversion from audio to text, which in turn streamlines the Engine's processing. The most probable matches are what the Engine returns.

Our technology is a speaker independent solution. Anyone can speak to our Engine and as long as they're saying the words the Engine is expecting to hear they'll be understood.

The Speech Engine is distinguished from other speech solutions. It does not provide dictation or voice verification. Voice recognition is often used in security solutions where the software determines who you are not what you're saying.

LumenVox is a core technology provider, meaning our engine is integrated into your application. Developers can write applications using our application programming interface (API), a standards–based solution like media resource control protocol (MRCP), or using a voice platform that has already written an interface to our Engine.

We've completed interoperability testing on Avaya, Asterisk, Holly and many other speech platforms. We're always looking for more platform partners. If you're interested in becoming a platform partner email us for more information.

Our Windows–based Speech Tuner gives you the ability to fine–tune and maintain your speech applications. You can transcribe call data, make on–the–fly Engine changes and then test those new settings instantly for effectiveness with recorded calls. We have extensive documentation on the Speech Tuner on our Support site.

Case Studies

We've helped our customers build some great applications, too. Larry Rushing of AccelMark came to us with a program used by taxi–dispatching and other companies. We helped him rewrite incredibly complex grammars that now allow an IVR to take taxicab requests with complete addresses.

We also helped Redmond Software improve their Spanish language OnStar applications accuracy by 42%. Offering development assistance on projects like these is just another example of how we are willing to help our partners develop impressive IVR solutions. Read More
