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.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
