Abstract:     A set of intonation intervals for a chosen dialect are applied to the intonational contour of a phomene string derived from a single set of stored linguistic units, e.g., phonemes. Sets of intonational intervals are stored to simulate or recognize different dialects or languages from a single set of stored phonemes. The interval rules preferably use a prosodic analysis of the phoneme string or other cues to apply a given interval to the phoneme string. A second set of interval data is provided for semantic information. The speech system is based on the observation that each dialect and language possess its own set of musical relationships or intonation intervals. These musical relationships are used by a human listener to identify the particular dialect or language. The speech system may be either a speech synthesis or speech analysis tool or may be a combined speech synthesis/analysis system.

First Claim:
Show all 42 claims
I claim:     1. A method of operating a speech synthesis system comprising the steps of:
  • generating a string of linguistic units containing pitch data by selecting linguistic units from a first memory segment of the system which correspond to characters in a text string and concatenating the selected linguistic units together in a second memory segment of the system;
  • selecting locations within the pitch data of the string of linguistic units;
  • retrieving a first set of dialect intervals for a first selected dialect, the first set of dialect intervals selected from a set of melodic intervals as being indicative of the first selected dialect and stored in a dialect table in a third memory segment of the system; and
  • applying the first set of dialect intervals to the pitch data at the selected locations so that synthesized speech of the first selected dialect produced.
