A method for adjusting an instant messaging control mechanism can include the steps of determining a control setting for an instant messaging control mechanism based upon a calendar application entry, and responsive to the determining step, automatically adjusting the instant messaging control mechanism to the control setting. In one embodiment, the determining step can be performed by a calendar application to which the calendar application entry corresponds and can be performed responsive to a calendar event. In a further embodiment, the calendar application can establish a time at which the control setting is to be adjusted. The adjusting step can occur at approximately the established time, where the calendar event can occur in advance of the established time.

The method of identifying excess noise in a computer system includes first recording a silence sample; second recording an isolated noise sample while operating a computer system component in isolation from other computer system components; comparing signal characteristics of the silence sample with signal characteristics of the isolated noise sample; and, attributing the isolated noise sample to the isolated computer component when the signal characteristics of the silence sample differ by a preset threshold from the signal characteristics of the isolated noise sample. The inventive method can further include logging the signal characteristics of the silence sample and the isolated noise sample; reporting excess noise identified in the identifying step; and, suggesting a remedy for the identified excess noise.

Process for identifying excess noise in a computer system

An automatic gain control method in accordance with the inventive arrangements can include the following steps. Initially, an audio signal can be provided to an audio device which has a range of permissible signal level settings and a signal level controller for establishing a particular signal level setting. In addition, an actual signal level can be measured for the audio signal at an established signal level setting. The measured actual signal level further can be stored in a volume map along with the corresponding established signal level setting. Following the storage of the measured actual signal level in the volume map, a different signal level setting can be established using the signal level controller. Subsequently, the actual signal level can be re-measured and the re-measured actual signal level and corresponding established different signal level setting can be stored in the volume map. Finally, the volume map can be used during an audio processing session to determine a signal level setting for the audio device, wherein the signal level setting corresponds to a desired actual audio signal level. In one aspect of the present invention, the method can also include detecting a hysteresis condition in the volume map.

Audio device characterization for accurate predictable volume control

A method of automatically adjusting volume of speech generated by a text-to-speech application can include measuring an ambient noise level of an audio environment. A target volume for speech output generated by a text-to-speech application can be calculated based in part upon the ambient noise level. A volume of speech generated by the text-to-speech application can be automatically adjusted responsive to the performed calculation.

Compensating for ambient noise levels in text-to-speech applications

A method and a system for improving recall of speech data in a computer speech system can include a plurality of speech cache management steps including providing a speech cache, receiving a speech system input and identifying a speech event in the received speech system input, the speech event comprising speech data. Subsequently, the speech data can be compared to pre-determined speech cache entry criteria; and, if the speech data meets one of the pre-determined entry criteria, at least one entry can be added to the speech cache, the at least one entry corresponding to the speech data. Additionally, the speech data can be compared to pre-determined speech cache exit criteria; and, if the speech data meets one of the pre-determined exit criteria, at least one entry can be purged from the speech cache, the at least one entry corresponding to the speech data. The entry criteria can include frequently used speech data, recently used speech data, and important speech data. Similarly, the exit criteria can include least frequently used speech data associated with each entry in the speech cache, least recently used speech data associated with each entry in the speech cache and least important speed data associated with each entry in the speech cache.

Method of managing a speech cache

A computer system has a notification manager for playing a message to a user by selecting one of a plurality of audio notifications. The method includes the step of setting a priority level for each notification arriving into a queue. The notification is inserted into a position in the queue based upon the priority level of the notification, such that the audio notifications at the queue top have a generally higher priority than audio notifications at the queue bottom. The notification at the top of the queue can be selected if the priority level of the notification is greater than a predetermined gate level. Once a notification is selected, a message corresponding to the selected notification is played to the user.

Audio notification management system

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 adjusting audio input signal gain in a speech system can include seven steps. First, an upper and a lower threshold can be predetermined in which the upper and lower threshold define an optimal range of audio data signal amplitude measurements. Second, a frame of unpredicted digital audio data samples can be received. Each sample can indicate an amplitude measurement of the audio data signal at a particular point in time. Third, a maximum signal amplitude can be calculated for a configurable measurement percentile of the unpredicted digital audio data samples. Fourth, the audio input signal gain can be incrementally adjusted downward if the maximum signal amplitude exceeds the upper threshold. Conversely, fifth, the audio input signal gain can be incrementally adjusted upward if the maximum signal amplitude falls below the lower threshold. Sixth, additional frames of unpredicted digital audio data samples can be received. Finally, seventh, each of the third through the sixth steps can be repeated with the received additional frames until the calculated maximum signal amplitude falls within the optimal range of audio signal amplitude.

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.

In a computer system adapted for text-to-speech playback, a method for instructing a user in performing a task having a plurality of steps can include retrieving a textual instruction from a location in an electronic storage device of the computer system. The textual instruction can correspond to one or more of the steps in the task. The textual instruction can be displayed in a task automation user interface, and a text-to-speech (TTS) conversion of the textual instruction can be executed. The steps can be repeated until all textual instructions corresponding to each step in the task have been retrieved and TTS converted.
