A communication management system manages the exchange of messages between devices using different communication networks and/or protocols. A sender device may transmit a message (e.g., a short message service “SMS” message) to a destination associated with a traditional “landline” phone number. The message may be delivered over a traditional landline phone network. The communication management system can receive the message via the phone network, process the message, and provide the message to one or more electronic devices over a packet switched network, such as a local area network or the Internet. The electronic devices may use chat-based application software to process and display the message, provide robust message handline functionality, and facilitate responses to the message. |

Current distributed message queuing services are designed to share resources in order to fulfill greater amounts of information; however, resource sharing often leads to correlated failures, task distribution problems, and misaligned load balancing of those shared resources. By maintaining a queue of publish request messages to be retrieved by message processors when the workload of the message processors is available, the enqueued messages are processed and fanned-out in order to provide information in the messages to the subscribers without latency or loss of data. |

Dynamic resource allocation for sensor devices on a cellular network
A method and associated systems for on-demand cellular-network bandwidth allocation in response to continuously changing populations of sensor devices. A sensor device adds itself to or deletes itself from a cluster of sensors. A physical controller that manages the cluster detects this change, identifies a resulting change in the cluster's bandwidth requirements, and stores this information in a local database. When such a sensor-population change satisfies a triggering condition, the controller requests that a network-management component of the cellular network adjust the controller's bandwidth allocation. The network-management component aggregates this and similar requests from all connected controllers in a global database, and when controller bandwidth requirements satisfy a second triggering condition, the component, using a standard API, asks the network-management component to reprovision the component's virtual bandwidth allocation. The component then distributes the adjusted bandwidth among its sensor-cluster controllers, which in turn allocate their adjusted bandwidths among their sensor devices. |

The calculation module performs a specific operation on the vocabulary probabilities corresponding to the same candidate vocabulary, to generate a plurality of corresponding operation results. The determination module determines whether each of the operation results is greater than a score threshold, and stores at least one output result that is greater than the score threshold to the first database. |

Methods and systems for providing a corrected voice command
Methods and systems for providing a correct voice command. One system includes a communication device that includes an electronic processor configured to receive a first voice command via a microphone and analyze the first voice command using a first type of voice recognition. The electronic processor determines that an action to be performed in accordance with the first voice command is unrecognizable based on the analysis using the first type of voice recognition. The electronic processor transmits the first voice command to a remote electronic computing device accompanying a request requesting that the first voice command be analyzed using a second type of voice recognition different from the first type of voice recognition. The electronic processor receives, from the remote electronic computing device, a second voice command corresponding to the action and different from the first voice command, and outputs, with a speaker, the second voice command. |

Generating transcription information based on context keywords
A service for generating textual transcriptions of video content is provided. A textual output generation service utilize machine learning techniques provide additional context for textual transcription. The textual output generation service first utilizes a machine learning algorithm to analyze video data from the video content and identify a set of context keywords corresponding to items identified in the video data. The textual output generation service then identifies one or more custom dictionaries of relevant terms based on the identified keywords. The textual output generation service can then utilize a machine learning algorithm to process the audio data from the video content biased with the selected dictionaries. The processing result can be utilized used to generate closed captioning information, textual content streams or otherwise stored. |

Domain adaptation in speech recognition via teacher-student learning
Improvements in speech recognition in a new domain are provided via the student/teacher training of models for different speech domains. A student model for a new domain is created based on the teacher model trained in an existing domain. The student model is trained in parallel to the operation of the teacher model, with inputs in the new and existing domains respectfully, to develop a neural network that is adapted to recognize speech in the new domain. The data in the new domain may exclude transcription labels but rather are parallelized with the data analyzed in the existing domain analyzed by the teacher model. The outputs from the teacher model are compared with the outputs of the student model and the differences are used to adjust the parameters of the student model to better recognize speech in the second domain. |

Squeaker cap for a water bottle used in a dog cruncher toy
A device mounts to a water bottle and produces sounds when the bottle is chewed by a dog, and includes a cap and squeaker. The cap includes: a body with a first opening on a first side defining an interior surface of a cavity, with a plurality of internal threads; and a second opening on a second side being in fluid communication with the cavity. A plurality of fingers are spaced about the second opening, and extend toward the first side, being at a first angle with respect to an axis of the interior surface. The squeaker is inserted into the second opening, and a protruding region of its housing causes the fingers to deform to a second angle with respect to the axis, after which the plurality of fingers nest between an end flange and the protruding region. Internal threads mount the device to threading of the water bottle. |
