  • Patent number: 8041556
    Abstract: A Chinese to English Translation Tool (CETT) locates pre-existing translations of phrases and increases probabilities for a match by searching independently of proper nouns and Western characters. The CETT comprises an enhancement program, a search program and a display program. The CETT is adapted to access a translation database, a proper noun table, and an unmatched translation table. The translation database is a central repository of an accumulated body of translated literature. The proper noun database is a table showing the associations between English and Chinese for proper nouns.

  • Patent number: 7899665
    Abstract: Embodiments of the present invention can gather data from native language sources to produce a valid collation sequence that is appropriate for a particular language and application. Sequences of characters in this data are tested to determine strength levels used by the given language. The data is also recursively probed with other sequences to test for contractions and identify expansions. Sequences in the data may then be compared against a known or predetermined sequence to generate a set of sorting rules that is specific to the language and application. The rules are formatted to replicate the sorting order found in the data.

  • Patent number: 7774192
    Abstract: A method for text alignment of a first document and a second document that is a translation version of the first document. The method first divides paragraphs of the first and second documents into sub-sentential segments according to the punctuations in the language of the first and second documents. Each of sub-sentential segments corresponds to a plurality of words. After the sub-sentential segmenting process, pairs of alignment units are summarized from the first and second documents. The alignment units in the first and second documents are then aligned and scored mainly based on the probability of corresponding punctuations. To increase the alignment accuracy, the pairs of alignment units can also be aligned and scored based on at least one of length corresponding probability, match type probability, and lexical information. The method allows for fast, reliable, and robust alignment of document and translated document in two disparate languages.

  • Patent number: 7742916
    Abstract: A method for evaluating the processing delay of a speech signal contained in data packets received in a receiver terminal having a telephony module during a voice call to a terminal sending the data packets over a packet-switched network. The method includes the step of obtaining from the received data packets a stream of audio packets containing the speech signal. Within a predetermined decoding time, the stream of obtained audio packets is decoded and a first reconstituted speech signal is created. At least a portion of the speech reconstituted by the telephony module is duplicated to create a second reconstituted speech signal. The time difference between the first and the second reconstituted speech signals is determined. The processing delay of the speech signal in the receiver terminal is calculated from at least the determined time difference between the reconstituted first and second speech signals and the predetermined decoding time.

  • Patent number: 7742914
    Abstract: A method of reducing noise in an audio signal, comprising the steps of: using a furrow filter to select spectral components that are narrow in frequency but relatively broad in time; using a bar filter to select spectral components that are broad in frequency but relatively narrow in time; analyzing the relative energy distribution between the output of the furrow and bar filters to determine the optimal proportion of spectral components for the output signal; and reconstructing the audio signal to generate the output signal. A second pair of time-frequency filters may be used to further improve intelligibility of the output signal. The temporal relationship between the furrow filter output and the bar filter output may be monitored so that the fricative components are allowed primarily at boundaries between intervals with no voiced signal present and intervals with voice components. A noise reduction system for an audio signal.

  • Patent number: 7725324
    Abstract: Signals of different channels are combined into one mono signal. A set of adaptive filters, preferably one for each channel, is derived in a respective filter adaptation unit. When an adaptive filter is applied to the mono signal it reconstructs the signal of the respective channel under a perceptual constraint. The perceptual constraint is a gain and/or shape constraint. The gain constraint allows the preservation of the relative energy between the channels while the shape constraint allows more stability by avoiding unnecessary filtering of spectral nulls. The transmitted parameters are the mono signal, in encoded form, and the parameters of the adaptive filters, preferably also encoded. The receiver reconstructs the signal of the different channels by applying the adaptive filters and possibly some additional post-processing.
