W3C published yesterday-- 14 October 2008 -- a standard that will simplify the development of Web applications that speak and listen to users. The Pronunciation Lexicon Specification (PLS) 1.0 is the newest piece of W3C's Speech Interface Framework for creating Web applications driven by voice and speech.
PLS can reduce the cost of developing these applications by allowing people to share and reuse pronunciation dictionaries. In addition, PLS can make it easier to localize applications by separating pronunciation concerns from other parts of the application.
"Standard pronunciation lexicons were a missing piece in the W3C Speech Framework," said Paolo Baggia, Director of International Standards at Loquendo and editor of the PLS 1.0 specification. "I'm very happy to have actively contributed to filling this gap. As a result, starting today people can create '100% standard' voice applications."
Voice Interaction Part of W3C's One Web Vision
Real-world voice-driven Web applications abound, though people may not always realize they are interacting with a Web service; examples include airline departure and arrival information, banking transactions, automated phone appointment reminders, and automated telephone receptionists. By one estimate, over 85% of Interactive Voice Response (IVR) applications for telephones (including mobile) use W3C's VoiceXML 2.0 standard.
"There are 10 times as many phones in the world as connected PCs. Phones will become the major portal to the Web," said James A. Larson, co-Chair of the Voice Browser Working Group, which produced the new standard. "Speech recognition is not yet widely associated with the 'visual Web', but this will change as devices continue to shrink and make keyboards impractical, and as cell phones become more prevalent in regions with low literacy rates."
Asking for directions while driving and hearing the response through speech synthesis illustrates how practical "hands-free" applications can be to mobile users. Voice applications also benefit people with some disabilities (such as vision limitations) and people who cannot read.
W3C considers voice access to be one piece of more general "multimodal" access, where users can use combinations of means to interact: voice input, speech feedback, electronic ink, touch input, and physical gestures (such as those used in some video games). The Voice Browser Working Group and the Multimodal Interaction Working Group are coordinating their efforts to make the Web available on more devices and in more situations.

AI implications: Engineer's model lays groundwork for machine-learning device

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
