Implementations relate to techniques for providing context-dependent search results. A computer-implemented method includes receiving an audio stream at a computing device during a time interval, the audio stream comprising user speech data and background audio, separating the audio stream into a first substream that includes the user speech data and a second substream that includes the background audio, identifying concepts related to the background audio, generating a set of terms related to the identified concepts, influencing a speech recognizer based on at least one of the terms related to the background audio, and obtaining a recognized version of the user speech data using the speech recognizer.

A process for real-time data exchange allows for sharing data, including metadata such as user data and phone data, between multiple handsets so that handsets may automatically display such data upon initiation or establishment of a telephone call, and in some arrangements throughout the life of the call. In this way, the need for subsequent data transmissions is reduced or eliminated, making bandwidth usage more efficient and conserving battery power.

A system for presenting media data to communication clients in the course of a communication data exchange between the communication clients in a telecommunication network includes: a storage engine, configured to store a plurality of media data files; an application control server, configured to receive media data file selection signals from at least one of the communication clients in the course of the communication data exchange, and to select media data files from the storage engine based on the received media data file section signals; and a communication processing server, configured to exchange media data with the communication clients and to retrieve the selected media data files from the storage engine, for simultaneously presenting the retrieved media data files at the communication clients in the course of said communication data exchange.

A stream server manages connections by multiple clients. The stream server receives, sends and manages streams for each client. The stream server analyzes incoming streams and maintains a database of device signatures and a database of user profiles based on the analyzed data. The stream server receives a stream from a client, analyzes the stream to identify an applicable device signature, user profile, or both, and modifies the stream. Modification of the stream may include filtering noise, placing the user in receive-only mode, ending a session for a user, adjusting metadata, etc. In addition, modification of the stream may vary based on the role or authorization of the user, or based on commands from one or more of the users.

Methods, systems, and computer readable media for conference session management are described. A first request is received from a user device to join a conference session. The first request includes a credential and an indication that the user device is to join the conference session in a passive mode. The credential received from the user device is verified. Upon successful verification of the credential received from the user device, the user device is added to the conference session in the passive mode, wherein audio and video from the conference session are not transmitted to the user device. A user device state indicator associated with the user device is set to passive.
