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: Electron highway inside crystal

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...

Im Focus: Significantly more productivity in USP lasers

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:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

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...

Im Focus: Quantum Particles Form Droplets

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...
