A method for enabling a user to proactively reduce the likelihood of audio feedback in an application requiring audio input and output, comprising the steps of: generating a graphical user interface (GUI) display screen including a first area for displaying information about preventing audio feedback and a second area for user selections and controls; displaying a list of available audio outputs in the second area; prompting the user to select one of the audio outputs from the list; prompting the user to select one of a plurality of muting options for each selected one of the audio outputs; and, displaying in the GUI display screen an explanation for each one of the plurality of muting options, whereby muting selections for proactively reducing the likelihood of audio feedback can be made based on user experience and knowledge. Only one of the muting option explanations is displayed at a time, responsive to the user selection of one of the muting options.

Preventing audio feedback

A method for guiding a user through trouble shooting a wrong audio source among a plurality of audio sources, comprises the steps of: (a) generating a GUI display screen including a first area for displaying information about testing an audio input device, a second area for displaying instructions and status information and for providing dynamic feedback and a third area for user selections and controls; (b) displaying a list of available audio sources in said third area; (c) prompting said user to select an audio source from said list; (d) prompting said user to test said selected audio source; (e) in the event said test is unsuccessful, prompting said user to select any other audio source identified in said third area; (f) prompting said user to test said any other audio source in said list; and, (g) repeating steps (e) and (f) until one of said audio sources is tested successfully or each of said audio sources is tested unsuccessfully.

Trouble shooting a wrong audio source

A method for connecting and optimizing audio input devices, comprises the steps of: determining an audio input type; generating a first GUI display screen for prompting and enabling user selection of an audio input device; generating a second GUI display screen for prompting and enabling user connection of the audio input device; testing the connected audio input device; configuring audio settings of the connected audio input device; and, storing for later retrieval an association of the connected audio input device and the configured audio settings. The audio settings are configured and the association is stored only if the testing step is successful. The second GUI display screen can include a device specific image and device specific instructions.

Connecting and optimizing audio input devices

A method and system for improving the speech command recognition accuracy of a computer speech recognition system uses event-based constraints to recognize a spoken command. The constraints are system states and events, which include system activities, active applications, prior commands and an event queue. The method and system is performed by monitoring events and states of the computer system and receiving a processed command corresponding to the spoken command. The processed command is statistically analyzed in light of the system events and states as well as according to an acoustic model. The system then identifies a recognized command corresponding to the spoken command.

Method and apparatus for improving speech command recognition accuracy using event-based constraints

A method for enabling user selectable input devices for dictation or transcription in a speech application, comprising the steps of: establishing a registry of dictation and transcription device descriptions, each of the descriptions including a device specific image, a device specific set of device-connecting instructions and a device specific list of audio configuration parameters; building dynamic tables containing information retrieved from the registry; establishing and storing a plurality of enrollments, each of the enrollments representing a speech file of user specific training data corresponding to at least one of a specific audio input device and a specific audio environment; and, generating GUI display screen using the information in at least one of the dynamic tables to enable user selection any input device in the registry for which one of the enrollments is available, for use as a dictation or transcription input to the speech application.

User selectable input devices for speech applications

A method for maintaining input device identity in a speech application, comprising the steps of: storing a plurality of enrollments, each of the enrollments representing a speech file of training data associated with at least one of a specific audio input device and a specific audio environment for a specific user; generating a graphical user interface (GUI) display screen for prompting and enabling user selection of at least one of an audio input device and an audio environment; and, retrieving one of the enrollments responsive to the user selection, for use in a dictation or transcription session.
