LumenVox Automated Speech Recognizer (ASR)
LumenVox Automated Speech Recognizer (ASR) is a software solution that converts spoken audio into text, providing users with a more efficient means of input. Resources can be utilized more effectively when less time is spent on data input.
Speech recognizer software compares spoken input to a list of phrases to be recognized, called a grammar. The grammar is used to constrain the search, enabling the ASR to return the text that represents the best match. This text is then used to drive the next steps of your speech-enabled application.
Speech recognition is typically used in Interactive Voice Response (IVR) systems, which allow computers and humans to communicate with one another through speech. You have used speech recognition on an IVR If you have ever had to “Say the name of the person you want to talk to…”
LumenVox’s ASR is integrated with more than 25 voice platforms. Developers can write applications using our application programming interface (API) or a standards-based solution such as media resource control protocol (MRCP). This makes installation, implementation, and deployment easy for users of those platforms.
The LumenVox Speech Recognizer also supports Natural Language Understanding (NLU) applications through the development of Statistical Language Models (SLM). These advanced speech development techniques provide end users with a more natural speech interface.
Available in 32 and 64-bit versions of Linux and Windows, the hardware-independent Speech Recognizer powers speech solutions and platforms deployed in Enterprise and SMB environments worldwide.
LumenVox Supported Languages

LumenVox also supports the W3C’s Semantic Interpretation for Speech Recognition (SISR) recommendation, Speech Recognition Grammar Specification (SRGS), and Voice Extensible Markup Language (VXML). Developers familiar with these types of industry standards will be able to quickly and effectively write applications.
The LumenVox Speech Recognizer 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. Our technology is a speaker-independent solution. Anyone can speak to our Recognizer, and it will match their spoken audio to phrases from the grammar.
How LumenVox Speech Recognition Works
- The engine loads a list of words to be recognized. This list of words is called a grammar.
- Audio from a speaker is captured by a microphone or telephone. This audio is turned into a waveform, a mathematical representation of sound.
- The engine looks at features — distinct characteristics of sound — derived from the waveform and compares them with its own acoustic model. The engine searches its acoustic space, using the grammar to guide this search.
- It determines which words in the grammar the audio most closely matches and returns a result
