Quantum mechanics provides several features useful for datacenter networking. The no cloning theorem, which states that it is impossible to mate a duplicate of an arbitrary, unknown quantum state, can be used to detect eavesdroppers. Entanglement allows two parties to have common knowledge of a shared state. These properties are being used today for quantum key exchange and quantum computing, but they are currently too expensive for general use. Fortunately, we can use classical mechanisms to get a close enough approximation of these quantum properties to solve some important problems in distributed computing. Nothing we describe here is quantum mechanical. Rather, we show that it is possible to use classical mechanisms to emulate some properties of quantum mechanics, which enable us to address interesting problems in distributed computing. The engineering insight, is that we can get closer to achieving these properties than might be expected through conventional thinking. The key to obtaining the properties we desire is to make the inherently asynchronous system temporarily locally synchronous for the operations we need. In this patent, we describe how to classically emulate the parts of the no cloning theorem and entanglement that we need for datacenter networking. We then demonstrate how those approximations to quantum behavior can be used to solve important problems in distributed computing, such as ‘exactly-once’ semantics in an environment where failures occur and can be healed without applications needing to know.

Determining a language for speech recognition of a spoken utterance received via an automated assistant interface for interacting with an automated assistant. Implementations can enable multilingual interaction with the automated assistant, without necessitating a user explicitly designate a language to be utilized for each interaction. Implementations determine a user profile that corresponds to audio data that captures a spoken utterance, and utilize language(s), and optionally corresponding probabilities, assigned to the user profile in determining a language for speech recognition of the spoken utterance. Some implementations select only a subset of languages, assigned to the user profile, to utilize in speech recognition of a given spoken utterance of the user. Some implementations perform speech recognition in each of multiple languages assigned to the user profile, and utilize criteria to select only one of the speech recognitions as appropriate for generating and providing content that is responsive to the spoken utterance.

This disclosure relates to answer prediction in a speech processing system. The system may disambiguate entities spoken or implied in a request to initiate an action with respect to a target user. To initiate the action, the system may determine one or more parameters; for example, the target (e.g., a contact/recipient), a source (e.g., a caller/requesting user), and a network (voice over internet protocol (VOIP), cellular, video chat, etc.). Due to the privacy implications of initiating actions involving data transfers between parties, the system may apply a high threshold for a confidence associated with each parameter. Rather than ask multiple follow-up questions, which may frustrate the requesting user, the system may attempt to disambiguate or determine a parameter, and skip a question regarding the parameter if it can predict an answer with high confidence. The system can improve the customer experience while maintaining security for actions involving, for example, communications.
