Our R&D on technologies for application services makes effective use of the network. Technologies for information navigation, user-centric appliances, and Quality of Experience (QoE) design offer friendly support to users by providing appropriate information. Speech, audio & language, and video & image technologies combine to realize natural and high-valued-added communication services. We are also studying an information integration platform, which makes it possible to develop large and highly reliable information systems.

Technology for Business Intelligence

Voice Mining for Contact Center

This technology efficiently extracts information that is useful for operating a contact center efficiently, increasing revenue, and enhancing customer satisfaction, from a huge amount of communication speech logged in the contact center. We are developing voice mining technology, which consists of extremely large vocabulary speech recognition technology (supporting 10 million words) that converts conversational speech data into text with high accuracy, complaint extraction technology that supports the identi?cation of issues for business improvement, and anger detection technology that utilizes non-verbal information such as the tempo of a dialog.

We are undertaking R&D on the core network technologies for the next-generation network (NGN) towards the realization of a ubiquitous broadband society, network platform technologies which support a variety of services on our next-generation network (NGN), advanced security technologies for safe and secure broadband ubiquitous services and various environmental and energy technologies towards the earth-friendly information sharing society.

Technology that Supports Public Services

Healthcare Platform for EHR and PHR Services

Health and medical records of an individual are stored piecemeal in different places: hospital, pharmacy and home. To realize EHR/PHR^*1 that securely integrates all these, it is essential to integrate different technologies in a sophisticated manner, such as technologies for mapping the IDs of individual records and controlling access to records. We are developing software that allows interworking between the EHR infrastructure that handles sensitive medical data, such as medical history and test results, and the PHR infrastructure that handles daily health data, such as weight and blood pressure, in order to allow integration of and secure access to health and medical data.

We are undertaking R&D in the areas of broadband and ubiquitous technology, electronics technology, photonics technology, communication science, physics and materials science to create new principles and concepts that will bring about a dramatic change in society, and to exploit ICT to realize such deep communication that is capable of conveying what users have in mind.

Optical Transmission Technology for
an Ultra-High-Capacity Optical Network

Digital Coherent Optical Transmission Technology

To accommodate the Internet trafficc growth in the future, NTT is studying digital coherent optical transmission technology that makes it possible to build a highly-reliable, high-capacity optical backbone network economically. By introducing massive DSP^*2 into the field of optical transmission technologies, we have developed real-time DSP technology to operate at a data rate of 100 Gbit/s per wavelength. We have further evolved this technology to achieve a long-haul, high-capacity transmission experiment with the record spectral efficiency of 10 bit/s/Hz at 400 Gbit/s per wavelength.
