Abstract: The present embodiments relate to providing near real-time communications from a public network to a private network. A first computing device in a public network can obtain data packets to be provided to the private network from an application executing on the first computing device. A trust module executed by the first computing device can authenticate the user, application, and the data packets to be provided to the private network and add metadata relating to the sending user, recipient user, etc. The data packets can be forwarded to the private network via a cross-domain system (CDS). The metadata and the digital signature on the data packets can be verified by a trust module executing on a second computing device in the private network. The second computing device can receive the data packets and store the data packets for subsequent actions to be performed in the private network.

Abstract: Voice command matching during testing of voice-assisted application prototypes for languages with non-phonetic alphabets is described. A visual page of an application prototype is displayed during a testing phase of the application prototype. A speech-to-text service converts a non-phonetic voice command spoken in a language with a non-phonetic alphabet, captured by at least one microphone during the testing phase of the application prototype, into a non-phonetic text string in the non-phonetic alphabet of the voice command. A phonetic language translator translates the non-phonetic text string of the voice command into a phonetic text string in a phonetic alphabet of the voice command. A comparison module compares the phonetic text string of the voice command to phonetic text strings in the phonetic alphabet of stored voice commands associated with the application prototype to identify a matching voice command. A performance module performs an action associated with the matching voice command.
