Appeal No. 1998-0650
Application 08/548,794
Significantly, the court concluded its analysis of the
mathematical algorithm issue as follows: "The question of
whether a claim encompasses statutory subject matter should
not focus on which of the four categories of subject matter a
claim is directed to . . . but rather on the essential
characteristics of the subject matter, in particular, its
practical utility." Id. With respect to the Freeman-Walter-
Abele test, the Federal Circuit held the district court erred
in applying it. According to the court, after Diehr and
Chakrabarty were decided by the Supreme Court, the test had
"little, if any, applicability to determining the presence of
statutory subject matter." Id. at 1601.
Appellant's claim 1 recites a
method for generating a statistical representation
of intonational feature information for a text-to-
speech system, the method comprising the steps of:
(a) annotating . . .; (b) with a computer means,
generating a set of structural information regarding
the predetermined text; (c) with the computer means,
generating said statistical representations of
intonational feature information based on the set of
structural information and the intonational feature
annotations; and (d) storing said statistical
representation for use in training a text-to-speech
system.
