  • Patent number: 11749131
    Abstract: Reading comprehension of a user can be assessed by presenting, in a graphical user interface, sequential reading text comprising a plurality of passages. The graphical user interface can alternate between (i) automatically advancing through passages of the reading text and (ii) manually advancing through passages of the reading text within the graphical user interface which is in response to user-generated input received via the graphical user interface. An audio narration is provided during the automatic advancing of the reading text. An audio file is recorded during the manual advancing of the reading text which is used to automatically determine an estimated level of reading comprehension of the user. Data characterizing the determined level of reading comprehension of the user can then be provided (e.g., displayed, loaded into memory, stored on a hard drive, transmitted to a remote computing system, etc.). Related apparatus, systems, techniques and articles are also described.

  • Patent number: 10755595
    Abstract: Computer-implemented systems and methods are provided for scoring content of a spoken response to a prompt. A scoring model is generated for a prompt, where generating the scoring model includes generating a transcript for each of a plurality of training responses to the prompt, dividing the plurality of training responses into clusters based on the transcripts of the training responses, selecting a subset of the training responses in each cluster for scoring, scoring the selected subset of training responses for each cluster, and generating content training vectors using the transcripts from the scored subset. A transcript is generated for a received spoken response to be scored, and a similarity metric is computed between the transcript of the spoken response to be scored and the content training vectors. A score is assigned to the spoken response based on the determined similarity metric.

  • Patent number: 9613638
    Abstract: Systems and methods are provided for generating an intelligibility score for speech of a non-native speaker. Words in a speech recording are identified using an automated speech recognizer, where the automated speech recognizer provides a string of words identified in the speech recording, and where the automated speech recognizer further provides an acoustic model likelihood score for each word in the string of words. For a particular word in the string of words, a context metric value is determined based upon a usage of the particular word within the string of words. An acoustic score for the particular word is determined based on the acoustic model likelihood score for the particular word from the automated speech recognizer. An intelligibility score is determined for the particular word based on the acoustic score for the particular word and the context metric value for the particular word.
