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: Goodbye, silicon? On the way to new electronic materials with metal-organic networks

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.

Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles

Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...

Im Focus: Disrupting crystalline order to restore superfluidity

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.

We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
