Experience LumenVox’s Industry Leading Accuracy through its Next-generation ASR Engine with Transcription

Industry leading accuracy

With its end-to-end Deep Neural Network (DNN) architecture, not only does the engine deliver industry leading accuracy but makes it easy for our customers to quickly add new languages and non-native speaking accents through our single language model approach.


Migrate legacy speech applications

Customers can migrate over 80% of grammars and confidence values from legacy applications to the LumenVox ASR with ease.

Deploy in any environment

LumenVox provides complete flexibility in the way our customers deploy their speech applications whether it is on-premises, multi-cloud, or a hybrid model.

Build Dynamic Voice Experiences Affordably and at Scale

The new engine, built on a foundation of artificial intelligence (AI) and deep machine learning, far exceeds competitors to deliver the most accurate speech-enabled customer experiences. 

What makes the new LumenVox ASR engine unique is its end-to-end DNN architecture and its state-of-the-art speech recognition processing capabilities. The new ASR engine not only accelerates the ability to add new languages and dialects but provides a modern toolset to expand the language model that can serve a more diverse base of users. 

Standards & Language Support

Our adoption of standardized protocols and development tools make it easy to replace your existing ASR with LumenVox. Our Media Server supports MRCP v1 and 2, we are VXML and PCI compliant, and our grammars can be written in GrXML or ABNF, with SISR and SRGS capabilities.

By ensuring that industry standards are at the core of our technology, developers can build speech-enabled applications quickly and efficiently through the LumenVox API or MRCP (media resource control protocol).


Extensive language support

LumenVox accelerates the ability to add new languages and dialects through its end-to-end Deep Neural Network (DNN) architecture and state-of-the-art speech recognition processing capabilities.

How Speech Recognition Works


Speech recognition represents an exciting and dynamic set of opportunities to create great customer experiences. Speech applications today range from self-service applications such as banking, voice enabled chatbots, and mobile applications that allow users to speak commands and compose messages using your voice. There are also burgeoning applications such as virtual assistants and audio mining for industries to use for research and analysis.

LumenVox does not need a complete phonetic lexicon for training new language models, it needs only transcribed audio, which allows for universal understanding of accents in any language model. It also speeds up the process of adding new language models or enhancing existing models. This also allows our customers to easily extend and adapt the default language models for their own needs, without having to deal with phonetic spellings and lexicons.
