VTT introduces unique, human voice-based guidance system for mobile phones

08.06.2004


Route directions prove particularly useful for the visually impaired

VTT Technical Research Centre of Finland has developed a unique guidance system for mobile phones, directed and directing by voice. The system provides relief for the everyday life of the visually impaired, in particular for their use of public transportation, but is also suitable for guiding consumers with normal eyesight and people travelling a lot in their work.

The benefit of the guidance system developed by VTT is the introduction of a voice interface for a normal mobile phone. The system is of particular help when using public transportation, but it also contains a great number of other functions and data services.



The guidance system is constantly in touch with public and real time databases: bus, train and tram routes and schedules, information about roadworks, news and weather services, as well as other information useful for the visually impaired. In addition to planning your trip, the system is capable of guiding you to the bus/train/tram stop, informing you of the arrival of the vehicle and telling you where to get off, as well as guiding your path from the starting point to your destination. With the help of satellite positioning, a visually impaired person can also store walking routes that have already been tested and proven good, with precision of within a few metres. The system is not a replacement for the white cane or the guide dog, but serves as a complement and opens up new possibilities for the visually impaired.

This guidance system, developed by VTT, is currently undergoing a test run. The system can already utilise the walking and public transportation routes of the road works database of the city of Helsinki’s construction office. Useful information is also contributed by e.g. train schedules and real time data on domestic flight arrivals and departures.

The voice-based service, which utilises positioning, will become useful also for other parties in the future: companies, associations and individual consumers. Voice-guided queries while on the run have proved easy to use also for the seeing consumer.

Technically, the voice interface of VTT’s guidance system is based on voice synthesis carried out in the mobile phone, and an analysis and identification of speech made in the server computer. Voice recognition is independent of the speaker. The system server utilises textual data available on the Internet when making data searches, and also conducts searches from various databases. Results are sent to the user’s mobile phone. The voice interface is currently available only in Finnish.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
