摘要： A method and system for pronunciation assessment based on distinctive feature analysis is provided. It evaluates a user's pronunciation by one or more distinctive feature (DF) assessor. It may further construct a phone assessor with DF assessors to evaluate a user's phone pronunciation, and even construct a continuous speech pronunciation assessor with phone assessor to get the final pronunciation score for a word or a sentence. Each DF assessor further includes a feature extractor and a distinctive feature classifier, and can be realized differently. This is based on the different characteristic of the distinctive feature. A score mapper may be included to standardize the output for each DF assessor. Each speech phone can be described as a “bundle” of DFs. The invention is a novel and qualitative solution based on the DF of speech sounds for pronunciation assessment.

摘要： A detachable projection module and an electronic device having the same integrate an optical engine and an image processing unit into an independent detachable module, where the module case is fixedly connected to a device body of the electronic device, so that projection module can receive image signals from the electronic device and convert the received image signals into projection signals to be projected onto a surface near the device body of the electronic device. Through a dedicated or generic connector interface, the detachable projection module may be removed from one electronic device and be mounted to another electronic device, giving an electronic device capability of equipping a projection module to extend the electronic device with a secondary display or empower an electronic device, which has no display at first, with display ability.
