Abstract
Official abstract text for this publication.
Disclosed herein are systems, methods, and non-transitory computer-readable storage media for detecting and correcting abnormal stress patterns in unit-selection speech synthesis. A system practicing the method detects incorrect stress patterns in selected acoustic units representing speech to be synthesized, and corrects the incorrect stress patterns in the selected acoustic units to yield corrected stress patterns. The system can further synthesize speech based on the corrected stress patterns. In one aspect, the system also classifies the incorrect stress patterns using a machine learning algorithm such as a classification and regression tree, adaptive boosting, support vector machine, and maximum entropy. In this way a text-to-speech unit selection speech synthesizer can produce more natural sounding speech with suitable stress patterns regardless of the stress of units in a unit selection database.
First claim
Opening claim text (preview).
We claim: 1. A method comprising: receiving a stress pattern for both a language and an accent in the language, the stress pattern being associated with words in the language; detecting, based on 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; and modifying, via a processor and prior to waveform synthesis, the incorr…
