W3C Moves Forward on New Extensions for Voice Technologies and the Web

07.12.2005


New Version of SSML to include Internationalization features; VoiceXML 3.0 to incorporate Speaker verification



The World Wide Web Consortium (W3C) announced new work on extensions to components of the Speech Interface Framework which will both extend Speech Synthesis Markup Language functionality to Asian and other languages, and include speaker verification features into the next version of VoiceXML, version 3.0. Addressing both areas expands both the reach and functionality of the framework.

Working Group Internationalizing SSML


The Speech Synthesis Markup Language (SSML), a W3C Recommendation since 2004, is designed to provide a rich, XML-based markup language for assisting the generation of synthetic speech in Web and other applications. The essential role of the markup language is to provide authors of synthesizable content a standard way to control aspects of speech such as pronunciation, volume, pitch, rate, etc. across different synthesis-capable platforms.

While these attributes are critical, additional attributes may be even more important to specific languages. For example, Mandarin Chinese, the most widely spoken language in the world today, also has the notion of tones - the same written character can have multiple pronunciations and meanings based on the tone used. Given the profusion of cellphones in China - some estimate as high as over one billion - the case for extending SSML for Mandarin is clear in terms of sheer market forces. Including extensions for Japanese, Korean and other languages will ensure that a fuller participation possible of the world on the Web.

Speaker Verification Extension to Be Included in VoiceXML 3.0

Another feature users are demanding of telephony services and the Web is speaker verification.

"Identity theft, fraud, phishing, terrorism, and even the high cost of resetting passwords have heightened interest in deploying biometric security for all communication channels, including the telephone,” said Ken Rehor of Vocalocity, newly elected Chairman of the VoiceXML Forum and participant in the W3C Voice Browser Working Group. “Speaker verification and identification is not only the best biometric for securing telephone transactions and communications, it can work seamlessly with speech recognition and speech synthesis in VoiceXML deployments."

Until now, most vendors have compensated for this missing feature by making a custom fix for their services. The result has been a set of divergent technologies that do not interoperate. Thanks to requirements contributions from the VoiceXML Forum’s Speaker Biometrics Committee, the W3C Voice Browser Working Group has been able to identify the features needed for a standardized speech verification module. The Working Group is now beginning to address these requirements.

Timing Perfect for New Participants

Given the depth and breadth of the announced new work, as well as plans for additional features for VoiceXML 3.0, this is a perfect time for new companies, researchers and other interested parties to join W3C and participate in the latest developments for voice technologies and the Web. Among potential critical contributors are those from the research and industrial sectors throughout Asia in the areas of Asian languages and speaker verification, to allow for the best possible expertise in the development of standards that truly serve the needs of Web users worldwide. More information on the W3C Voice Browser Activity and on joining W3C is on the W3C Web site.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
