Abstract

Disclosed is a method combining modules from text-to-speech conversion programs to produce lifelike animations of characters speaking. Such animations can be combined with other forms of computer-generated simulations or with hand-drawn cartoons.

Realistic Animation using Baseforms and Phonological Rules

      Disclosed is a method combining modules from text-to-speech
conversion programs to produce lifelike animations of characters
speaking.  Such animations can be combined with other forms of
computer-generated simulations or with hand-drawn cartoons.

      In this method, the following modules from text-to-speech
conversion programs are combined:
  1.  A set of phonological rules.
  2.  A list of spelled words and corresponding baseforms.
  3.  A program for applying the phonological rules to the
       baseforms.
  4.  Optionally, a computer program for generating baseforms
       from spellings.

The list of spelled words and corresponding baseforms may be produced
by hand or from an on-line dictionary.  The optional program for
generating baseforms is used to handle proper names and other words
not in the list.

      In addition to these modules, a new module is developed for
associating and time-aligning the pronunciations generated using the
first four modules with corresponding mouth and facial movements
needed for lifelike animation.

      This method is independent of the natural language to be
spoken, as these modules can be constructed for any language.  This
method may be used, for example, in the translation of animations
from one language to another.
