Aculab nears 100% accuracy with its highly responsive Deep Neural Network (DNN) live speaker/answering machine detection.

Aculab’s AI innovations enable businesses to work at peak efficiency whilst in line with modern compliance regulations.

Aculab, a leading provider of deployment proven telephony products to the global communications market, is pleased to announce that its Live Speaker Detection (LSD), also known as Answering Machine Detection (AMD), is now achieving near-perfect accuracy.

Aculab’s new industry-leading LSD / AMD algorithm will significantly reduce the proportion of misclassified calls. This is great for our customers, moving them a big step closer to getting their message through every time. stated Mark Luckin, Product Manager.

Exceptional levels of accuracy and responsiveness are required for three reasons: the minimisation of costs, the prevention of end-user annoyance, and compliance with legal and regulatory obligations. The cost issue is obvious - there are large savings to be made if agents do not have to waste time connecting to calls that are not answered by anyone. However the situation with regulatory compliance can be even more serious.

For example, in the UK, the regulator Ofcom specifies that no more than 3% of calls made within a 24-hour period can be abandoned, and that answered calls must be then connected to an agent, or the receiver played a message within two seconds of their initial “hello”. Similar regulations apply in many other countries, including the US.

Compliance with such regulations requires a quick and accurate method for detecting whether a call has been answered by a live person, as opposed to a machine.

Traditional technology has struggled to satisfy these demands, risking huge fines for call centres who cannot comply. This is an ongoing problem that still faces many companies on a regular basis.

The new Aculab Cloud LSD / AMD function comfortably exceeds legal requirements for accuracy and speed, producing a response within 1.5 seconds and with a typical error rate of less than 1.5%, meaning 98.6% accuracy and rising. This allows developers and service providers to meet regulatory obligations with room to spare. The new system is due for release in Q4 2020.

Aculab has a long history of innovation in the telephony IVR market, and has been continually at the forefront of developing technology, with cloud-based APIs and integrated Artificial Intelligence (AI). This has culminated in significant improvements in both accuracy and speed of response in its LSD / AMD technology.

The new system’s enhanced accuracy results from the inclusion of AI algorithms within a proprietary hybrid blend of traditional cadence-based analysis and state-of-the-art Deep Neural Network (DNN) technology. Together these technologies give best-in-class performance, running as part of a robust and reliable platform, Aculab Cloud.

This development provides important benefits for service providers and their end users. Those benefits include a significant reduction in the proportion of misclassified calls, an improved called-party experience, and the ability to meet strict industry regulations for agent connection times and abandoned calls.



Aculab hosted an informative webinar, titled “High Performance AI Broadcast Messaging in a Time of Crisis” on the 6th of October 2020 and the 14th of October.

We talked about the AI technology underpinning broadcast messaging, and how it helps companies and businesses to adapt their lines of communication in the wake of massive paradigm shifts, resulting from the global pandemic in this time of crisis.

We also have a practical demonstration of Aculab Cloud, showing you the ease of creating a Broadcast messaging service with all the cutting edge features Aculab Cloud offers.
