Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for secure communications in a digital engineering ecosystem. In some implementations, a digital platform receives a request from a user device to interact with a digital model. The digital platform determines whether a user operating the user device is authorized. In response to determining the user is authorized to access the digital platform, the digital platform generates a token that provides the user with access to the digital platform. The digital platform determines whether the request includes malicious activity. In response to determining that the request is absent of the malicious activity, the digital platform executes a digital thread that executes one or more operations using digital tools and the digital model. The digital platform provides data indicative of the one or more operations executing the digital thread to the user device.

Abstract: Methods, systems, and computer-readable storage media for providing reading performance feedback to a user from a voice recording of the user reading an arbitrary text. A target text comprising a text passage that a user intends to read and a user recording comprising an audio recording of the user reading the target text aloud are received from a user device. The user recording is converted to a user speech hypothesis comprising text corresponding to speech recognized in the audio recording. The user speech hypothesis is then compared to the target text to generate reading performance feedback comprising relevant differences between the speech in the user recording and the target text and the reading performance feedback is displayed to the user on the user device.
