Call Progress Analysis (CPA)


LumenVox Call Progress Analysis Features

The LumenVox Call Progress Analysis represents a new approach to increasing the effectiveness of your outbound dialing application. By leveraging our experience and technology in speech recognition, we can offer you assurance that the right message is being delivered to the right recipient.


Tone-based Detection - Let Our Experience Ensure Your Application's Success

Our tone-based detection represents a significant innovation compared to many other energy-based answering machine detection technologies. Most systems guess whether the call is connected to a human based on energy levels and timing queues, resulting in unacceptably inaccurate messaging applications.

Proven Technology - Trust in the Reliability of an Existing Product

LumenVox’s Call Progress Analysis technology is actually a specialized functionality of the LumenVox Speech Recognizer, version 9.5 or newer. You now have the dependability of LumenVox’s flagship ASR product driving your analysis.

Standards Support

Let industry standards simplify development. 

Media Server

supports MRCP v1 and 2

Compliant With

any VoiceXML or CCXML platform that also supports MRCP.


Product Familiarity - Use Your Experience to Ease Development

We have designed the technology to be easily dropped into existing platforms. From a technical perspective, you are simply loading a special grammar file and waiting for a return from the Speech Recognizer. This also means that it can run on any modern Windows release or supported Linux distribution.


Scalable Deployments - Grow Your Environment With Your Business

System resource requirements are relatively minimal, but may scale up for very large numbers of simultaneous detections. This extra system load is in addition to any speech recognitions the ASR may be performing.
