Echo residue is detected using speech application data. The echo residue is detected using a method that includes correlating audio data from an input channel with audio data from an output channel to obtain a correlation result. A determined value of the correlation result is compared with a predetermined threshold. The audio data for the input channel is categorized in a first category when the determined value of the correlation result is greater than the predetermined threshold. The audio data for the input channel is categorized in a second category when the determined value of the correlation result is less than the predetermined threshold. The first category includes audio data that is determined to include an acceptable level of residual echo. The second category includes audio data that is determined to include an unacceptable level of residual echo.
