Abstract: Systems, methods, and software are disclosed herein that improve the instruction of prosody in the context of software applications and services. In various implementations, a service analyzes an audio recording of a user reading text aloud to determine the prosody of the reading. The service provides data to an application indicative the prosody, as well as a reference prosody for the text. The application may then display of a visualization of a comparison of the user prosody for the text to the reference prosody for the text for consumption by users, e.g., a teacher or the reader.

Abstract: A method of identifying reading passages for reading progress can include receiving a set of error-indicated phonemes, wherein the set of error-indicated phonemes correspond to pronunciation errors identified in a recorded audio file from an individual reading an assigned passage aloud; determining corresponding error-indicated phonetic rules for each error-indicated phoneme of the set of error-indicated phonemes using a mapping of phonemes to phonetic rules; identifying at least one content passage from a set of content passages that satisfies a condition with respect to the error-indicated phonetic rules; and providing the at least one content passage for a new assignment for the individual to read aloud.

Abstract: In non-limiting examples of the present disclosure, systems, methods and devices for mapping hyperarticulated sounds to text units are presented. A plurality of textual units may be received. The plurality of textual units may be processed with a natural language processing engine. A sentence structure for the plurality of textual units may be identified, wherein the sentence structure comprises a plurality of words. The plurality of words may be processed with a text-to-speech engine. A text-to-speech output comprising a plurality of pronunciations may be identified, wherein each of the plurality of pronunciations corresponds to a syllabic unit of one of the plurality of words. A hyperarticulated vowel sound may be mapped to each syllabic unit from the text-to-speech output. A pronunciation instruction corresponding to each hyperarticulated vowel sound may be caused to be surfaced.

Abstract: Apparatus and methods for conveying a flow of oil-containing liquid into an oil separation skim tank, and a skim tank incorporating such apparatus and methods, are disclosed. One such apparatus includes at least one diffuser, the diffuser defining an intake opening configured to receive the flow of oil-containing liquid and an exhaust opening configured to convey the flow of oil-containing liquid into the skim tank. The diffuser is configured to cause the flow of oil-containing liquid to have a greater horizontal width at the exhaust opening than at the intake opening, while minimizing vertical divergence of the flow at the exhaust opening.

Abstract: A method and a mix box for mixing oil sand and water to form a substantially uniformly mixed oil sand slurry is provided. The mix box has an open top end for receiving pre-crushed oil sand and water and a sloped bottom end having a discharge outlet and includes a plurality of profiled shelves positioned within the mix box. The substantially uniformly mixed oil sand has a substantially uniform flow distribution and therefore, when screened, reduces uneven wear on the screens.
