Voice and language recognition yields city information

03.08.2004


New in town and don’t know a soul! An evening free, but no idea where to go. What do you do? According to CATCH-2004, you consult one of their interactive systems for the information you need in your native language, and go straight to your preferred venue!

Working prototypes in Athens, Cologne and Helsinki

The CATCH 2004 IST project aimed to provide EU citizens with interactive, multilingual and multimode access to a wide range of information services and systems, offered by providers from both the public and the private sector.



By project close in June 2002, the participants had developed working prototype systems in three European cities, Helsinki, Athens and Cologne. These systems offered information on city events such as sporting activities, local cultural happenings and even TV and radio programme data, and could all be interrogated and reply in more than one language.

Participants in the project included IBM France (lead contractor), additional IBM technical units in Athens, Heidelberg and Prague, Nokia of Finland and OTE in Greece, as well as the Olympic Committee and the cities of Athens, Cologne and Helsinki.

Voice and language recognition

To achieve their ends, the project participants developed a multilingual interface that could handle both direct and spoken-language interrogation, a unified architecture that could handle input from a variety of client devices, and voice-enabled access to the Web databases connected to this architecture.

Key to the success of the system were the voice and language recognition capabilities, based on IBM’s proprietary ViaVoice™ technology, that were inbuilt. This core technology allowed the system to recognise a user’s native language without the need to select from any menu. The system was able to recognise the user’s language simply from the first sentences spoken, then would switch automatically to that language.

In addition, the CATCH-2004 system was a multimode interface, in that this information could be provided not only via city information kiosks, but also via the telephone, using either landline or mobile phones, or the PC. Interaction with the user had to be possible via speech, text or graphics, depending on the characteristics of the access device.

“It was the multilingual and multimode aspects together that were the real test,” says project coordinator Jacques Saint-Blancat of IBM France. “Integrating these two capabilities together into one system, and then making sure it all worked for the system trials, was quite a challenge.”

Multilingual information interface

In Helsinki, the system was set up as a ‘City Events Information’ source that could be interrogated either in Finnish or in English. The application proved so successful that it was extended to include details of radio and TV programmes, allowing users to consult radio and TV programme information on various channels, and enabling them to ask for a list of programmes based on programme name, type, channel, date, time and performer.

The Athens installation was provided with two distinct applications, one focusing on local cultural activities, the other on Olympic sporting events in preparation for the Athens Olympics in 2004. Here the project participants were provided with a database of information on events at the Olympics, for which they developed a voice XML interface based on the contents. Both applications could be consulted using either a Web browser or the telephone. Equally, both applications were capable of handling queries in three languages, English, German or Greek.

Results incorporated into working systems

During system trials, the Helsinki installation handled around 300 calls during the month of October 2001 alone. The results from this pilot were then analysed and used to fine-tune the application, and the final version was exhibited at the IST 2001 conference and exhibition. In addition one of the participants, the city of Cologne, has integrated parts of the CATCH-2004 technology into its existing city information booths.

The project has certainly helped the participants involved, believes Saint-Blancat. “The experience has been very positive for IBM. For our part, what we have learnt has helped us give our voice-response systems greater reliability, as well as making them more versatile.”

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

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,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

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...

Im Focus: Circular RNA linked to brain function

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...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

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...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

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...
