LAS VEGAS — At a press conference at the recent Consumer Electronics Show (CES) in Las Vegas, NPR, Harris Corporation, and Towson University announced the global accessible radio technology initiative and provided the first live demonstration of the accessible radio technology.

 The group also announced a new research center for developing future technologies on the campus of Towson University near Baltimore. Additional plans call for the establishment of an international consortium of equipment manufacturers, broadcasters, and other organizations to help foster broad adoption of the initiative.

The initiative will be spearheaded by the three founding organizations and will leverage cutting-edge HD Radio™ technology to enable hearing-impaired people to “see” live radio content on specially equipped receivers by applying television closed-captioning processes to radio broadcasts. The technology also will provide audio cues and voice prompts, as well as advanced radio reading services, for those visually impaired and blind.

“Digital radio technology makes it possible–for the first time–to serve the sensory impaired,” says Mike Starling, vice president and chief technology officer of NPR. “Beyond developing the technology, this initiative will ensure the accessibility of these radio services at minimal costs.”

HD Radio enables station operators to split their broadcasts up into multiple channels, providing several CD-quality channels for their audiences. Through this accessible radio initiative, a small amount of the total data capacity will be used to carry textual data that will be shown live on a screen on new versions of HD Radio receivers, essentially providing a closed-captioning transcript of live broadcasts for the deaf. Initially, the closed-captioning text will be created by live, court-reporting-type captioners at individual stations and networks. Ultimately, the initiative is hoping to leverage advanced speech-to-text translation software applications that one day allow expansion of captioning across the radio dial. Specially equipped HD Radio receivers are in development with several features to provide the visually impaired audience with better access to broadcasts, such as audio prompts that notify which direction the tuner is going, what channel the radio is on, and larger, easier-to-read text on the radios.

More than 1,500 radio stations are currently broadcasting in HD Radio in the United States. Over half of the CPB-qualified stations have been awarded HD Radio conversion grants by the Corporation for Public Broadcasting. According to current estimates, by 2010, all 825 public radio stations should be broadcasting digitally.

During the press conference, the organizations showcased the first over-the-air transmission of the accessible radio technology using a signal from WX3NPR, a special temporary station authorized by the FCC for the live broadcast. Attendees at the press conference watched the text transcript of the NPR flagship morning news magazine “Morning Edition” on the HD Radio receiver’s viewing screen, which is what a hearing-impaired listener will see using the technology. Additionally, the demonstration carried a digital radio reading service that will assist the visually impaired with daily readings of current books, newspapers and magazines.

Following the demonstration, the participating organizations unveiled details for the International Center for Accessible Radio Technology (ICART), which will be headquartered at Towson University in Towson, Md. Towson will house the primary administrative and academic research office for the initiative, with NPR Labs in Washington, DC, providing technology R&D and software development, and Harris Corporation supplying transmission and research support at its radio broadcast technology center in Cincinnati.

Members of the global initiative went on to detail plans to further study and understand the challenges faced by the sensory-impaired population in accessing radio broadcasts, and develop methodologies to address those issues through cutting-edge technologies. To ensure that the effort represents the widest range of participants and fosters the broadest possible adoption, organizers said they will work to bring together policymakers, broadcasters, transmission equipment companies, and receiver manufacturers from around the world. Presently, the initiative has more than a dozen members, representing virtually every aspect of the “microphone to loudspeaker” chain: broadcasters, network content providers, infrastructure and transmission equipment companies, and receiver manufacturers.

In addition to founding members NPR, Harris, and Towson University, supporting organizations include iBiquity Digital Corporation, Delphi, NDS, Radiosophy, Helen Keller Institute, Carl and Ruth Shapiro Family National Center for Accessible Media at WGBH(NCAM), Northern Virginia Resource Center for Deaf and Hard of Hearing Persons, and the G3ict, an Advocacy Initiative of the United Nations Global Alliance for ICT and Development.

NPR, Harris, and Towson will jointly determine strategic direction of the organization, with assistance from the initiative’s full membership. NPR will provide much of the content, Harris will provide much of the transmission-related technologies, and Towson will provide research into the needs of the sensory-disabled population and will house the primary ICART facility on its campus.

“We’re working very closely with radio stations around the world to ensure they have the right technical infrastructure in place for this initiative,” says Howard Lance, chairman, president and CEO of Harris Corporation. “The new HD Radio transmission systems we’re installing are tailor-made for this effort, as their digital capabilities will make it relatively easy for stations to transmit live textual transcripts to HD Radio receivers.”

“There is tremendous need for accessible radio for sensory-impaired people, including the deaf, hard-of-hearing, blind, visually impaired, print impaired, deaf/blind, and mobility impaired,” said Dr. Ellyn Sheffield, assistant professor of psychology at Towson and co-director of ICART. “There is no question this initiative will have a profound impact on the quality of millions of people’s lives. Finally, sensory-disabled individuals will have access to all radio programming, as well as radio emergency alerts and vital disaster recovery information.”
