Brief HistoryIn the 1950s, Bell Laboratories developed the first effective speech

recognizer for numbers.

In the 1970s, the ARPA Speech Understanding Research project developed

the objective of automatic speech recognition as the understanding of

speech not merely the recognition of words.

By the 1980s, two distinct types of commercial products were available:

The first offered speaker-independent recognition of

small vocabularies useful for telephone transaction processing.

The second focused on the development of large-vocabulary

voice recognition systems so that text documentscould be created by voice dictation.

Over the past two decades, voice recognition technology

has developed to the point of real-time, continuous speech

systems that augment command, security, and content

creation tasks with exceptionally high accuracy.

BackgroundSIL

In March of 1999, AT&T, IBM, Lucent and Motorola founded

the VoiceXML Forum, to promote and to accelerate theadoption of VoiceXML-based applications worldwide.

The Voice Browser Working Group

, first established on 26March 1999, is charged with managing the W3C efforts in this area

and is currently chartered through 31 January 2009.

The W3C Speech Interface Frameworkisa suite of markup specifications addressing

the convergence of telecommunications

and the Web with the goal of bringing the

benefits of Web technology to the telephone.

the ImpactSIL

open-source platform creates a more flexible architecture that minimizes

integration and customization and enables multimodal communication

development is greatly simplifieddeveloper only needs to use the SILs thatcontain features required by a specific application

decreasing the programming time and effortlowers the entry

barrier for creating Web-based telephony applications.

on Web Development

on Mobile SolutionsThe convergence of telecommunications and the Web is now bringing the benefits

of Web technology to the telephone, enabling Web developers to create

applications that can be accessed via any telephone, and allowing people to

interact with these applications via speech and telephone keypads.

the MarketSIL

The overall market for voice-recognition

technology jumped 100% in just two years

-Opus Research

The market for speech technology embedded in

devices is expected to quadruple by 2010

-DataMonitor

2008 will be the first year that

VoiceXML-based IVR shipments will

exceed more traditional applications.
