6. The method of claim 1 , further comprising synthesizing speech according to the corrected stress patterns.
1. A method comprising: receiving a stress pattern for both a language and an accent in the language; detecting, according to the stress pattern, incorrect stress patterns in selected acoustic units representing speech to be synthesized, wherein the selected acoustic units were selected by a separate unit-selection speech synthesizer; performing an analysis of the incorrect stress patterns, wherein the analysis comprises a word level analysis, a phrase level analysis, and a sentence level analysis on the incorrect stress patterns, wherein the word level analysis, the phrase level analysis, and the sentence level analysis are performed in series; and modifying, via a processor and prior to waveform synthesis, the incorrect stress patterns in the selected acoustic units according to the analysis, to yield corrected stress patterns, wherein the corrected stress patterns conform to the stress pattern for the language.
