A method for audio processing includes receiving a recording of a teleconference among multiple participants over a network, including an audio stream containing speech uttered by the participants and information outside the audio stream. The method further includes processing the audio stream to identify speech segments interspersed with intervals of silence, extracting speaker identifications from the information outside the audio stream in the received recording, labeling a first set of the identified speech segments from the audio stream with the speaker identifications, extracting acoustic features from the speech segments in the first set, learning a correlation between the speaker identifications labelled to the segments in the first set and the extracted acoustic features, and labeling a second set of the identified speech segments using the learned correlation, to indicate the participants who spoke during the speech segments in the second set.

Metadata-based diarization of teleconferences

A method and system for executing distributed locks in a locking system is disclosed. The system includes receiving a lock request including at least a lock name of a resource to place a lock on; determining a shard key at least based on the lock name and a prefix value, wherein the locking system includes a set of database instances, and wherein the prefix value is a number of database instances in the locking system; sending the lock request to at least two database instances in the set of database instances to place the lock in an entry pointed by the shard key; acknowledging the lock request when all of the at least two database instances acknowledge the lock request; and dismissing the lock request when at least one database instance of the at least two database instances cannot acknowledge the lock request.

A method and system for live migration of an index in a document store are provided. The method includes creating a new index based on a change request, wherein the change request designates at least one change relative to a current index, wherein the new index includes all mappings and settings of the current index together with the at least one requested change, wherein the new index and the current index are properties of the document store; initiating a reindexing process of the new index by copying documents from the current index to the new index, wherein the current index remains active during the reindexing of the new index; resharding the current index; and upon successful completion of the reindexing process, deleting the current index and directing all write and read requests to the new index.

Live data migration in document stores

A method and system for providing consistency in read-after-write operations in a multi-replica relational database system (RDS) are provided. The method includes receiving a read transaction to read data from a database (DB) replica of the multi-replica RDS; obtaining counter values of DB replicas in the multi-replica RDS, a counter value of determines a current version of recent data stored in the respective DB replica; determining a write replica out of the DB replicas in the multi-replica RDS; determining if there is an available read replica, a read replica is a replica other than the determined write replica having counter value at least equals to a counter value of the write replica; and waiting, when there is no available read replica, a preconfigured time window to allow all replicas to synchronize with the write replica; and reading the data from a read replica when the preconfigured time window has elapsed.

Techniques for synchronous access to database replicas

A method and system for live migration of an index in a document store are provided. The method includes creating a new index based on a change request, wherein the change request designates at least one change relative to a current index, wherein the new index includes all mappings and settings of the current index together with the at least one requested change, wherein the new index and the current index are properties of the document store; initiating a reindexing process of the new index by copying documents from the current index to the new index, wherein the current index remains active during the reindexing of the new index; and upon successful completion of the reindexing process, deleting the current index and directing all write and read requests to the new index.

A method for audio processing includes receiving, in a computer, a recording of a teleconference among multiple participants over a network including an audio stream containing speech uttered by the participants and conference metadata for controlling a display on video screens viewed by the participants during the teleconference. The audio stream is processed by the computer to identify speech segments, in which one or more of the participants were speaking, interspersed with intervals of silence in the audio stream. The conference metadata are parsed so as to extract speaker identifications, which are indicative of the participants who spoke during successive periods of the teleconference. The teleconference is diarized by labeling the identified speech segments from the audio stream with the speaker identifications extracted from corresponding periods of the teleconference.
