Abstract (en)

The invention provides a speech synethesising apparatus in which a character string translator 1 converts each word in an encoded input character string into a phoneme string corresponding to the characters in the word using a word memory 2. Next, a variable phoneme detector 3 detects those phonemes in the string the values of whose prosodic parameters may be modified due to the existence of an influencing phoneme at another location in the phoneme string, by comparing each phoneme with phonemes stored in variable phoneme memory 4. If a variable phoneme is detected in the phoneme string, a search is made by an influencing phoneme detector 5 for influencing phonemes at the location in the phoneme string indicated by the variable phoneme detector. The variable phoneme memory stored, along with each variable phoneme, the predetermined relative location at which an influencing phoneme may be found. If an influencing phoneme is detected at the appropriate location relative to the variable phoneme the influencing phoneme detector will output data representative of a modification in the value of a selected parameter (duration, pitch or power) of the variable phoneme. The phoneme string is then delivered to a parameter value determining unit 7, where standard and modified data are combined. Finally, the phoneme string, parameter values, and modification data are supplied a parametric synthesizer 7, which assembles them into synthetic speech.
