Speech technology helps to discover treasures of knowledge


The outcomes of the “transLectures” project: the video platform “” shows video lectures with automatic subtitles in five European languages – the project partner EML European Media Laboratory, Heidelberg/Germany, and the Institut Jozef Stefan, Ljubljana/Slovenia, will continue to make subtitles available in even more languages.

Courses, lectures and talks: On the internet, you can find a huge collection of educational video material - treasures of knowledge that are still waiting to be discovered and distributed. The EU funded research project “transLectures” has provided tools to help discovering these treasures.

Universities, research institutions and companies from Spain, France, Slovenia, the UK, and Germany built a set of easy-to-use tools to add multilingual subtitles to educational video lectures. By these means, users can search, classify and analyze the videos much easier and make them accessible to a broad international audience, as well as to people with disabilities.

“transLectures” was co-ordinated by the Technical University of Valencia and funded by the EU with € 3.1 million. The Heidelberg-based EML European Media Laboratory implemented its speech recognition and transcription system to convert the audio automatically into text.

That way, more than 18.000 English and Slovenian lectures were automatically transcribed during the project, besides that also lectures in German, French, and Spanish language. The transcribed text appears as verbatim subtitles that can be activated with a “cc” button on the bottom of the video window. Moreover, many lectures were translated into other languages using machine translation tools.

The system is open and interactive. If necessary the user post-edits selected segments of the automatically created output to correct the subtitles. This helps to improve not only the referred subtitles but also future subtitle generation in the transLectures system.

At the end of the project the independent reviewers of the European Commission awarded the project an excellent overall evaluation. The educational videos with a topic range from astronomy to social sciences are available on the platform hosted by the project partner Institut Jozef Stefan (IJS), Ljubljana/Slovenia. EML and IJS intend to continue subtitling educational videos and enhancing the system, e.g. making it available in even more languages, like Chinese or Arabic. The first videos with Chinese subtitles are already online – waiting to be discovered.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
