  • Description

    An electronic device that makes it possible of speed up recorded speech while retaining the normal tone of the voice has been built by the American Foundation for the Blind......
    The American Foundation for the Blind records hundreds of Talking Books every year -- recordings made available to blind persons through the Library of Congress. Soon, many texts and magazines will be condensed by the Harmonic Compressor and added to libraries for the blind.

    SYNOPSIS: If this speech sounds unusual, it's because it's been compressed by a new electronic device to help blind persons hear a spoken text in half the normal time.

    The American foundation for the Blind makes these recordings at double speed by using the new Harmonic Compressor. Bell Telephone Laboratories provided the designs and the Foundations built the unit. Here, speech is recorded on tape at the usual speed.

    When the recorded tape is played back at double speed without using the Harmonic Compressor, it gives the voice the familiar "Donald Duck effect":
    However, when the tape is fed through the Harmonic Compressor's complex circuitry, the speed is doubled but the normal tone of the voice is retained.

    Thanks to this new electronic device, blind persons can now speed-hear books being read at about 400 words per minute, the same rate most sighted persons can read them in print.
