Abstract
A method for configuring an audio interface for a speech recognition application in a computer system comprises the steps of: (a) identifying at least one sound card present in the computer system capable of supporting speech; (b) displaying a at least one graphical user interface (GUI) prompting a user selection and connection of a microphone as an audio input device to the at least one sound card; (c) in the event the selected microphone is of an electret type and the selected sound card is of a type having a high gain range, displaying a second GUI prompting the user to connect a signal strength attenuator in series with the microphone, the microphone and the attenuator together having an operating characteristic corresponding to a dynamic microphone; (d) in the event the selected microphone is of a dynamic type, omitting step (c); and, (e) testing the connected microphone without regard to whether the connected microphone is of the electret or dynamic type.
