Podcasting has become very popular, mainly as a medium for entertainment. But it also holds huge potential for the visually impaired and others, such as dyslexics, who have reading difficulties. Simultaneously reading and listening to read-aloud news articles and scientific papers, for example, could increase readers' concentration and absorption of information. Such audio files would open a new world for the blind or partially sighted.

Software is available that translates text from digital files or directly from the Internet into a listener-friendly audio file, but it is expensive. Some freeware has built-in 'read out-loud' functions, but the quality is generally inferior.

Several newspapers and magazines already offer subscribers podcasts containing complete and navigable issues in read-aloud format. But the scientific press seems to be lagging behind. The Nature podcasts are a good start, but when shall we be able to listen to sections such as Research Highlights, News and Correspondence as downloadable audio?
