This study examines the role of Artificial Intelligence (AI) and Machine Learning in Real Time Communications (RTC). Advances in consumer-oriented AI technologies are now finding new applications and use cases as these capabilities become democratized. The communications industry, which was once at the forefront of many of these technologies, is now presented with a plethora of new options for improving existing applications, finding new cost advantages, and redefining existing communications modalities.

This study examines the use of machine learning and AI technologies in 4 distinct domains:

  • Speech analytics - extracting transcription and paralinguistic information for speech to provide insights;
  • Voicebots - the role of conversational AI as a feature and enabler for applications such as Interactive Voice Response (IVR);
  • Computer vision (CV) - use of advanced vision processing algorithms on video calling streams;
  • RTC optimization - using machine learning to optimize end-to-end network architecture and lower-level VoIP protocols.

The report authors are active industry participants helping companies enhance and build products with years of experience in technical, product management, and consulting roles applying new technologies with recent practical work with speech analytics, computer vision, voice bots, and performance algorithms. The research was compiled from more than 40 in-depth 1-on-1 interviews with key industry technology stakeholders, a web survey with nearly 100 distinct company respondents, and detailed product reviews of leading machine learning-based products, and AI in RTC solutions.

The research is designed to help product, strategy, and business development decision makers communications service providers, technology vendors, communications-centric app providers, and enterprise information technology organizations.

The report indicates most AI efforts in communications companies are focused on speech analytics. Established vendors and a growing number of startups are looking into AI technologies to improve their product offerings, create better experiences for their customers and increase their competitiveness. With limited skills in AI available, it is crucial for companies to start early on in their journey towards AI support. Most communications vendors are only starting this journey and will require major effort to catch-up with current technology leaders.

"AI and ML will transform every industry. When computers were introduced they were like bicycles for the mind. The introduction of AI is like the space shuttle" Said Omar Javaid, Chief Product Officer at Vonage. "This is an excellent and thorough report. It is written by people that actually understand technology and how products are made."

"There is a real demand for AI in communication products. Our partners are expecting us to have a plan for AI and the timing of this research is spot on." Said John Logsdon, CEO and Founder of This is Drum Technologies Ltd. "This report contains a wide and detailed view of the industry, assisting us in honing our AI roadmap for our web collaboration product."

Communications developers are interested in leveraging machine learning, but lack qualified staff to drive these efforts. Major AI cloud platform providers like Amazon, Google, and Microsoft present both promise and peril for communications app makers. They provide advanced AI APIs that can be used in RTC applications, but at the same time they often use better versions of these same APIs in their own competing communications services. The report authors advise, "The RTC industry needs to take a more proactive role in training its existing employees around ML methods and attracting ML graduates or it will continue to lose ground to other industries and outside players who will eventually come back to take RTC customers."
