Run time synthesizer adaptation to improve intelligibility of synthesized speech
First Claim
1. A method for modifying synthesized speech, the method including the steps of:
- generating synthesized speech based on textual input and a plurality of run-time control parameter values;
generating real-time data based on background noise contained in an environment in which the speech is reproduced;
converting the background noise into an electrical signal;
retrieving one or more interface models from a model database;
characterizing the background noise with the real-time data based on the electrical signal and the interface models; and
, modifying one or more of the run-time control parameter values based on the real-time data such that the intelligibility of the speech increases.

Abstract
A method and system provide for run-time modification of synthesized speech. The method includes the step of generating synthesized speech based on textual input and a plurality of run-time control parameter values. Real-time data is generated based on an input signal, where the input signal characterizes an intelligibility of the speech with regard to a listener. The method further provides for modifying one or more of the run-time control parameter values based on the real-time data such that the intelligibility of the speech increases. Modifying the parameter values at run-time as opposed to during the design stages provides a level of adaptation unachievable through conventional approaches.
