• Resumen

  • A new program can convert whispers into normal-sounding speech. Whispering is useful if people don't want to be overheard, but it's also unavoidable if their vocal cords are damaged. So an app that turns whispered words into full speech could be invaluable. One hurdle is that whispering cannot produce all the tones achieved by the vocal cords. That missing ingredient means it doesn't have an actual pitch. Hideaki Konno and his colleagues at Hokkaido University of Education in Japan played sounds with just one frequency to five people and asked them to whisper at those pitches. This established a link between their whispers and intended pitch.
