Abstract: Disclosed are systems and methods for generating a long-term signal level estimate during automatic gain control. In an example method, a computing device selects a first subset of an input signal, the input signal being a portion of a captured audio signal including at least a variable speech component. The computing device divides the first subset of the input signal into a first set of intervals. The computing device computes a first statistical measure of each interval of the first set of intervals. The computing devices generates a first statistical distribution based on the first statistical measure of at least a portion of the first set of intervals. The computing device determines the long-term signal level estimate based on one or more characteristics of the first statistical distribution. The computing device generates a first stage gain based on the long-term signal level estimate.

Each payload has a predefined time length. The conferencing server transmits the multiple time-contiguous containers to a consumer server.

Abstract: A versioning group cache system uses cache keys which each include, amongst other things, version information and a group key. When a cache key is first updated to include these, the cache system determines the group key and adds version information thereto to produce the cache key, which is mapped to cached data. When the cache key is later updated, the version information is updated to produce an updated cache key which is mapped to the cached data. The cache key updating is in response to a change request received at the cache system. The change request includes a command processable at the cache system in connection with cached data and/or cache keys. For example, the change request may be a request for a batch deletion of cache keys. The versioning group cache system fulfills the change requests with efficient use of system resources.

Abstract: A transcript of a conference (e.g., a video conference, an audio conference, or a telephone call with two or more participants) is processed to extract a conference summary. The transcript includes strings that are associated with respective timestamps and respective speaker identifiers. Speaker segments—sequences of consecutive strings attributed to the same speaker—are identified in the transcript. A speaker segment is selected based on its duration in time and one or more strings are selected from with the selected speaker segment for inclusion in the conference summary. A short video conference summary or a short audio conference summary is then generated using timestamps from the transcript associated with strings (e.g., sentences) that have been selected for inclusion in the conference summary. The short video or audio summary may be presented to users to enable efficient storage and transmission of information from the conference within a unified communications system.
