Abstract

The device disclosed here provides both visual and auditory feedback of speech utterances, e.g., to help a user in learning a foreign language. Visual feedback is obtained by moving a cursor on a graph representing supra-segmental speech parameters (e.g., amplitude, intensity, pitch frequency, voicing, either in isolation or in combination), synchronously with the playback of the corresponding sounds. Auditory feedback is obtained by playback of recorded speech utterances, either at normal speed or at low speed with preservation of the pitch frequency using a technique known as "sped speech".

Foreign Language Training Using Low Speed Speech and Graphical Feedback

       The device disclosed here provides both visual and
auditory feedback of speech utterances, e.g., to help a user in
learning a foreign language.  Visual feedback is obtained by moving a
cursor on a graph representing supra-segmental speech parameters
(e.g., amplitude, intensity, pitch frequency, voicing, either in
isolation or in combination), synchronously with the playback of the
corresponding sounds. Auditory feedback is obtained by playback of
recorded speech utterances, either at normal speed or at low speed
with preservation of the pitch frequency using a technique known as
"sped speech".

      The device consists of:
      1.   A microphone
      2.   A loudspeaker or earphones
      3.   An acoustic component to determine various parameters,
including pitch frequency, and to perform low-speed speech playback
using recorded speech and the corresponding pitch frequency.
      4.   A color display screen.
      5.   A memory device.
      6.   A control mechanism to coordinate the device operation.
      7.   Interface devices (e.g., keyboard, mouse, etc.) to allow
the user to communicate with the control mechanism.

      Using the interface devices to drive the control mechanism, the
user can retrieve sample utterances by native speakers from the
memory device, display the corresponding graphs and listen to them at
various spee...
