VoiceXML – Business Benefits

VoiceXML is the natural voice user interface for bringing web–enabled services to telephony usersMigration of IVR systems to web technologies

The web offers forums for standardizing proprietary protocols and APIsThe web offers solutions to distribution, scaling, security and robustnessWeb deployment mechanisms reduce time and cost of service introductionThe web is rich with tools and skilled developers

VoiceXML – Place in the Market

IVR replacement – cost savings through…Reduced development and deployment costsLeveraging existing web–enabled customer servicesEfficient exploitation of costly speech processors

Application portability and reusable componentsDeploying on a different voice browsers with little or modifications to the application code

Minimal coupling between the application server and the telephony infrastructure

Use of dynamic content is invisible to the voice browserCompetition makes for a healthy hosting marketplace

VoiceXML – Place in the Market

Reuse of Web concepts and tools for the development of speech applications

HTTP Server (Apache, ISS, ..)Application servers (BEA, WebSphere, Tomcat, ..)Languages (Java, ….)

Maintenance of different service access can be synchronizedDifferent media are published in a uniform way for different services (e.g. voice services, Web, WAP)

Multimodal servicesTreat voice access as one of a coherently handled set of customer–contact modesAsynchronous and simultaneous voice/visual modal services now possible

What Do the Analysts say??IVR is still the dominant Self-Service channel but is moving from Touch Tone to Speech.

Companies are moving from Touch-Tone IVR to Speech application as it supports more complex functionality and provides higher completion rates (Forrester)Well-designed voice user interfaces (VUI) can reduce call time by as much as 30% and compared to traditional IVR systems cut opt-out rates by 50% (Forrester - 2003)Increased IVR retention rate. Companies are up to 60% more likely to retain a caller within the IVR using speech vs. touch tone (Giga)Nearly a third of contact centers use speech recognition technology and a further 17% plan to install it during 2006. If contact centers implement these plans, almost 50% will be using speech recognition within a year …..and…those organizations considering speech solutions have mostly delivered on their plans (Merchants – 2006)

Hardware Partition: Each End User/Business Unit has own hardware.

Software Partition: Each End User/Business unit has own Application Server Instance but on shared hardware.

Logical Partition: End Users/Business Units share Application Server instances, but this enables 1000s of users of the platform.

Shared infrastructure and more efficient usage of resources.
