How a talking iPhone app can help save lives

Haiti earthquake survivor Dan Woolley used an iPhone app called Phone Aid to heal his injuries while he was stuck under the shambles of the hotel he was staying at. The app uses screenshots and speech to give emergency instructions. This is an example of how speech can help users better understand the content they are trying to access. In this particular case, the speech component was particularly useful in conveying essential information in the tragic surroundings the survivor was trapped in.
