Coded text is converted to phonetic data to drive a synthesis filter. Accent data are also obtained to derive a pitch contour for a variable pitch excitation source. Recognition of the beginning of a paragraph causes a pitch contour of higher pitch than the pitch at a later part of the paragraph. The initial pitch falls following each subgroup into which phrases are divided. In another aspect of the invention, accents within a phrase are assigned pitch values which are high for the first accent, less high for the last; and the remainder alternate between higher and lower lesser values.
