US Patent 7340397 Speech recognition optimization tool

A method of optimizing audio input for speech recognition applications can include identifying a source waveform and at least one optimization parameter, wherein the optimization parameter is configured to adjust audio input to a speech recognition application. The source waveform can be modified according to the optimization parameter resulting in a modified waveform. At least one optimization parameter can be synchronized with the source waveform. At least two time dependant graphs can be displayed, where the time dependant graphs can include the source waveform, the modified waveform, and/or a graph for the optimization parameter plotted against time.
