  • Publication number: 20190329390
    Abstract: A nail gun with dry fire prevention device includes a gun body, a nail magazine connected with the gun body, a trigger device, and an action assembly. The nail magazine is configured to house at least a nail. The action assembly includes an action member fixed on an outer side of the nail magazine and an operation member pivotally disposed at the action member. The operation member has a first and second portions disposed on two ends of the operation member, respectively. When the nail magazine is empty of the nail, the first portion enters the nail magazine, and the second portion blocks the trigger member, such that the trigger member is unable to be operated. Therefore, the dry fire operation of the nail gun without nails is prevented, improving the convenience of usage and the utility of the nail gun.

  • Publication number: 20090125299
    Abstract: A speech recognition system comprises at least a speech recognition engine and a display device that contains a signal status interface and a textual interface. The signal status interface is used to show a recording status, a speech processing status, or a complete speech recognition status based on waveforms display. The textual interface is used to show word units of the speech recognition results. Two sets of commands are connected with each waveform unit on the signal status interface and each word unit on the textural interface, respectively, in order to allow users to correct the recognition errors or to adjust the speech recognition system.

  • Publication number: 20070131205
    Abstract: A fuel efficiency enhancing device that is used inside or outside of the fuel tank of a motor vehicle is provided. The fuel efficiency enhancing device has a casing member made of Teflon, inside which far infrared and magnetic members are installed in a closed compartment without any contact to the external environment. The fuel efficiency enhancing device uses both the far infrared and magnetism to break up and activate the fuel molecules so as to achieve a superior fuel economy.

  • Publication number: 20060190268
    Abstract: A unified speech input dialogue interface, and a distributed multiple application-dependent language processing unit system with the unified speech recognition function and the unified dialogue interface are provided. The system not only provides a convenient user's environment, but also enhances the whole performance of speech recognition. The distributed multiple application-dependent language processing unit system uses a speech input interface so that the user can be familiar with a simple, unified interface. The system also improves the speech recognition accuracy and enhances the convenience of use by self-learning personalized dialogue model.

  • Publication number: 20060190261
    Abstract: A method of speech recognition and language-understanding analysis is provided. According to a segmental word-concept-tag compound N-gram model, an input speech is divided into a plurality of segmental phrases. Each segmental phrase is attached a tag to indicate whether said segmental phrase is a meaningful segmental phrase or a meaningless segmental phrase. The meaningless segmental phrases are deleted, and only the meaningful segmental phrases are reserved. The language-understanding analysis is carried out to the meaningful segmental phrases according to segmental sub-grammars.

  • Publication number: 20060173685
    Abstract: A method and apparatus for constructing new Chinese words by voice input is disclosed. The invention provides a method of adding new words to a speech recognition system, for example, a speaker-independent Chinese speech recognition system, for updating its vocabulary database. In the invention, voice signals indicating a description of Chinese characters/syllables are input sequentially, and feature parameters are derived from the voice signals. The feature parameters are compared with a description constraint unit to determine corresponding characters or syllables. The characters or syllables are stored in a storage unit. After confirmation by users, the characters or syllables are combined into a new word.

  • Publication number: 20060167684
    Abstract: In the present invention, a speech recognition method is provided. The speech recognition method includes steps of (a) receiving a speech from a user and recognizing the speech for generating a plurality of recognition results, (b) displaying the recognition results for the user to lock correct values in the recognition results, (c) determining whether the correct values are sufficient for searching a database, (d) saving the correct values as known values to narrow the recognition range and repeating step (a) to step (c) when the correct values are insufficient for searching the database, and (e) searching the database for a desired datum based on the correct values when the correct values are sufficient.

  • Publication number: 20050216276
    Abstract: A method of voice-inputting a Chinese character is provided. The method comprises: inputting a target character in a voice; generating a plurality of candidate characters including the target character based on a spelling of the target character; and selecting the target character from the plurality of candidate characters based on a description of the target character. Because the method combines the CSL and CDL mechanisms so that it can generates the accurate character.
