Abstract

See full text

Linguistic and/or extra-linguistic information is extracted from speech signals to provide measures that may then be compared to expected norms, individual baselines or other nominal or numeric criteria (according to particular psychomotor, perceptual, cognitive or emotional constructs) that are required for satisfactory performance of particular tasks, or that indicate a user's psychological or physical state. The user produces the speech signals in the context of a constrained voice-interactive dialog that utilizes prompts chosen such that the expected range of responses will exhibit low linguistic entropy. For example, the prompts may be interpreted by the user as requests for information, requests to read or repeat or paraphrase a word, sentence, or larger linguistic unit, requests to draw an inference, requests to complete, or identify elements in graphic or verbal aggregates (e.g., pictures or discourses), as examples to imitate, or any similar graphical or verbal presentation that conventionally serves as a prompt to speak. The display is presented though a device either integral or peripheral to a computer system, such as a local or remote video display terminal or telephone.
