Abstract: Implementations set forth herein relate to phasing-out of vehicle computing device versions while ensuring useful responsiveness of any vehicle computing device versions that are still in operation. Certain features of updated computing devices may not be available to prior versions of computing devices because of hardware limitations. The implementations set forth herein eliminate crashes and wasteful data transmissions caused by prior versions of computing devices that have not been, or cannot be, upgraded. A server device can be responsive to a particular intent request provided to a vehicle computing device, despite the intent request being associated with an action that a particular version of the vehicle computing device cannot execute. In response, the server device can elect to provide speech to text data, and/or natural language understanding data, in furtherance of allowing the vehicle computing device to continue leveraging resources at the server device.

Abstract: A system for automatically labeling data using conceptual descriptions. In one example, the system includes an electronic processor configured to generate unlabeled training data examples from one or more natural language documents and, for each of a plurality of categories, determine one or more concepts associated with a conceptual description of the category and generate a weak annotator for each of the one or more concepts. The electronic processor is also configured to apply each weak annotator to each training data example and, when a training data example satisfies a weak annotator, output a category associated with the weak annotator. For each training data example, the electronic processor determines a probabilistic distribution of the plurality of categories. For each training data example, the electronic processor labels the training data example with a category having the highest value in the probabilistic distribution determined for the training data example.

Abstract: Generating and/or recommending command bundles for a user of an automated assistant. A command bundle comprises a plurality of discrete actions that can be performed by an automated assistant. One or more of the actions of a command bundle can cause transmission of a corresponding command and/or other data to one or more devices and/or agents that are distinct from devices and/or agents to which data is transmitted based on other action(s) of the bundle. Implementations determine command bundles that are likely relevant to a user, and present those command bundles as suggestions to the user. In some of those implementations, a machine learning model is utilized to generate a user action embedding for the user, and a command bundle embedding for each of a plurality of command bundles. Command bundle(s) can be selected for suggestion based on comparison of the user action embedding and the command bundle embeddings.

Abstract: Systems and methods are described herein for locally interpreting a voice query and for managing a storage size of data stored locally to support such local interpretation of voice queries. A voice query is received and compared with a plurality of stored voice queries having similar audio characteristics. If a match is identified, text corresponding to the matching stored voice query is retrieved, and an action corresponding to the retrieved text is performed. If the locally stored table does not contain a stored voice query that matches the voice query, the voice query is transmitted to a remote server for transcription. Once the transcription is received from the remote server, the voice query and the transcription are stored in the table in association with one another.

Abstract: Embodiments described herein provide systems and methods for an Explicit Memory Tracker (EMT) that tracks each rule sentence to perform decision making and to generate follow-up clarifying questions. Specifically, the EMT first segments the regulation text into several rule sentences and allocates the segmented rule sentences into memory modules, and then feeds information regarding the user scenario and dialogue history into the EMT sequentially to update each memory module separately. At each dialogue turn, the EMT makes a decision among based on current memory status of the memory modules whether further clarification is needed to come up with an answer to a user question. The EMT determines that further clarification is needed by identifying an underspecified rule sentence span by modulating token-level span distributions with sentence-level selection scores. The EMT extracts the underspecified rule sentence span and rephrases the underspecified rule sentence span to generate a follow-up question.

Abstract: A method of presenting a signal to a speech processing engine is disclosed. According to an example of the method, an audio signal is received via a microphone. A portion of the audio signal is identified, and a probability is determined that the portion comprises speech directed by a user of the speech processing engine as input to the speech processing engine. In accordance with a determination that the probability exceeds a threshold, the portion of the audio signal is presented as input to the speech processing engine. In accordance with a determination that the probability does not exceed the threshold, the portion of the audio signal is not presented as input to the speech processing engine.

Abstract: Techniques for transferring control of a system-user dialog session are described. A first speechlet component may interact with a user until the first speechlet component receives user input that the first speechlet component cannot handle. The first speechlet component may output an action representing the user input. A system may determine a second speechlet component configured to execute the action. The system may send the second speechlet component a navigator object that results in the second speechlet component handling the user interaction that the first speechlet component could not handle. Once the second speechlet component is finished processing, the second speechlet component may output an updated navigator object, which causes the first speechlet component to either further interact with a user or cause a current dialog session to be closed.

Abstract: Systems, devices, and methods provide improved autonomous agents that are configured to respond to a user's query based on an emotion with which the query was expressed and a personality trait of the user. The agent may identify candidate answers to the query that are each associated with an emotion and/or a personality trait. The autonomous agent may utilize a predefined protocol set that indicates transitions between emotional states. A transition may correspond to an action associated with an emotion and/or a personality trait that, if performed, is likely to maintain a user in or transition the user to a preferred emotional state. The responses may be scored based at least in part their corresponding emotions and/or personality traits and in light of the transitions identified in the protocol set. A particular scored response may be selected and provided to the user in response to their query.
