Abstract: In one example embodiment, audio characteristics of audio signals are adjusted by a first machine learning model to reduce effects of a facial covering and produce adjusted audio signals. The audio signals correspond to resulting voice signals produced from the facial covering affecting original voice signals. Speech characteristics are predicted for the adjusted audio signals by a second machine learning model. Transformed audio signals corresponding to the original voice signals are produced based on the adjusted audio signals and predicted speech characteristics.

Abstract: In one embodiment, a method includes obtaining a request for a notification regarding an event associated with a first party and a first location. The request is received or otherwise obtained from a second party. The method also includes determining whether the second party is permitted to receive the notification, determining whether the event has occurred, sending the notification if the event has occurred and the second party is permitted to receive the notification. Sending the notification regarding the event includes sending the notification to the second party.

Abstract: A system for sharing presence-based time-zone information includes a database, and a controller. The database includes a plurality of presence profiles, each presence profile maintaining, for an associated network user, one or more network device identifiers and, for each network device identifier, a current presence status, indicating network availability, and current time-zone information based on geographic location. The controller is able to receive presence information, determine a matching one of the presence profiles, update the current presence status and the current time-zone information in the matching one of the presence profiles, generate shifted time-zone information, generate a presence update, identify a subscriber address for receiving the presence update, and transmit the presence update to the subscriber address.

Abstract: A method for facilitating a data session in a session protocol environment is provided that includes identifying a first endpoint and receiving a status indicator as to whether the first endpoint is available to participate in a communication session that involves the first endpoint and a second endpoint. In a more particular embodiment, the first endpoint is operable to recognize that the second endpoint is seeking to contact the first endpoint in order to conduct the communication session.

Abstract: A method for scheduling conference resources is provided, that includes receiving a request for a conference reservation. The request may include the identities of a plurality of proposed participants, a proposed start time, and at least one fixed resource criterion. In accordance with a particular embodiment of the present invention, a projected location of at least one of the proposed participants is automatically calculated. The projected location may be a location at which the at least one of the proposed participants is expected to be at approximately the proposed start time. The method may also include automatically calculating a projected location of at least one invitee of the conference. In accordance with this embodiment, the projected location of the at least one invitee may be used to select an optimal one of a plurality of fixed resources, that match the at least one fixed resource criterion.

Abstract: A system for monitoring connectivity status includes network traffic transport entities and an aggregation server. The network traffic transport entities transport network traffic and are able to monitor a portion of the network traffic, access one or more network traffic alert rules, apply the network traffic alert rules to the portion of the network traffic, and determine whether an alert is required based on the application of the network traffic alert rules. The network traffic transport entities are also able to, in response to a determination that an alert is required, generate an alert message. The aggregation server is able to maintain a connectivity status profile, receive the alert message from the network traffic transport entity, identify a matching one of the communication devices in the connectivity status profile, determine an updated network connectivity status for the matching communication device, and update the connectivity status for the matching communication device.

Abstract: In one embodiment, a method includes obtaining a request for a notification regarding an event associated with a first party and a first location. The request is received or otherwise obtained from a second party. The method also includes determining whether the second party is permitted to receive the notification, determining whether the event has occurred, sending the notification if the event has occurred and the second party is permitted to receive the notification. Sending the notification regarding the event includes sending the notification to the second party.

Abstract: A communication system for providing multi-modal call management includes a communication manager, a notification database, and a personal assistant. The communication system can receive a call, collect caller identification information, generate a call notification, and send the call notification to one or more communication devices through one or more communication protocols. The communication system can also receive a response to the call notification and initiate an action regarding the call based on the call notification response. The communications system can perform all of these activities while maintaining the call in an offering state. The call management system allows a system user to manage an outstanding call using one or more of multiple communication devices, identified by the communication manager as being associated with the system user.
