Abstract: A server supports multiple virtual assistants. It receives requests that include wake phrase audio and an identification of the source of the request, such as a virtual assistant device. Based on the identification, the server searches a database for a wake phrase detector appropriate for the identified source. The server then applies the wake phrase detector to the received wake phrase audio. If the wake phrase audio triggers the wake phrase detector, the server provides an appropriate response to the source.

Abstract: There is provided a computing system for training a model for spotting of a custom wake phrase, the system comprising a processor and a memory in communication with the processor, the memory storing instructions that, when executed by the processor, configure the computing system to: receive a request for training the model for a phrase spotter executable for spotting the custom wake phrase within audio input. The computing system is configured to: responsive to receiving the request, receive, at a user interface of the computing system: an input positive audio sample corresponding to spoken audio of the custom wake phrase; and train using the input positive audio sample, the model for the phrase spotter executable for a wake phrase recognition subsystem that, when deployed on a voice enabled computing device, recognizes subsequent audio input instances of the custom wake phrase based upon the training.

Abstract: The invention relates to a process for converting a feed stream comprising oxygenated lower aliphatic hydrocarbon compounds, especially methanol, to a product stream comprising aromatic hydrocarbons, especially BTX, which process comprises a step of contacting said feed with a catalyst composition La-M/zeolite, which consists essentially of from 0.0001 to 20 mass % (based on total catalyst composition) of lanthanum; from 0.0001 to 20 mass % of at least one element M selected from the group consisting of molybdenum, copper, cerium and caesium; zeolite in hydrogen form; and optionally a binder.

Abstract: The invention relates to a novel catalyst composition La-M/zeolite, which consists essentially of from 0.0001 to 20 mass % of La (lanthanum); from 0.0001 to 20 mass % of at least one element M selected from the group consisting of molybdenum (Mo), cerium (Ce) and caesium (Cs); a zeolite of the 10-ring structure type; and optionally a binder (mass % based on total catalyst composition). The invention also relates to the use of the catalyst composition according to the invention in various reactions, for examples in making aromatics from aliphatic hydrocarbons or oxygenated hydrocarbons with good selectivity and activity. The invention further relates more specifically to a process for converting a feed stream comprising oxygenated lower aliphatic hydrocarbon compounds, especially methanol, to a product stream comprising aromatic hydrocarbons and olefins, especially BTX, which process comprises a step of contacting said feed with the catalyst composition according to the invention.
