Abstract: A speech interface device is configured to detect an interrupt event and process a voice command without detecting a wakeword. The device includes on-device interrupt architecture configured to detect when device-directed speech is present and send audio data to a remote system for speech processing. This architecture includes an interrupt detector that detects an interrupt event (e.g., device-directed speech) with low latency, enabling the device to quickly lower a volume of output audio and/or perform other actions in response to a potential voice command. In addition, the architecture includes a device directed classifier that processes an entire utterance and corresponding semantic information and detects device-directed speech with high accuracy. Using the device directed classifier, the device may reject the interrupt event and increase a volume of the output audio or may accept the interrupt event, causing the output audio to end and performing speech processing on the audio data.

Abstract: Disclosed are various embodiments related to intercepting, modifying, and analyzing messages being exchanged between two entities. In one embodiment, among others, a method comprises intercepting messages being exchanged between a first entity and a second entity. The intercepted messages are modified to substitute sender information identifying the sender with proxy sender information such that the sender is anonymous to the intended recipient. The messages are also analyzed to determine at least one performance metric associated with the messages being exchanged.

Abstract: Described herein is a system for prompting a user for clarification when an automatic speech recognition (ASR) system encounters ambiguity with respect to the user's input. The feedback provided by the user is used to retrain machine-learning models and/or to generate new machine-learning models. Based on the type of ambiguity, the system may determine to retrain one or more ASR models that are widely used by the system or to generate/update one or more user-specific models that are used to process inputs from one or more particular users.

Abstract: Disclosed are various embodiments of a system. In one embodiment, among others, a method comprises intercepting a communication between a first party and a second party in a communication forum. The communication includes first party proxy information as an intended recipient information. The method further comprises accessing a communication pair using the intended recipient information. The intended recipient information is associated with second party proxy information. The second party proxy information is associated with second party information. Additionally, the method comprises determining whether the identity of the sender is valid.
