Method and apparatus for training a multilingual speech model set

The invention relates to a method and apparatus for training a multilingual speech model set. The multilingual speech model set generated is suitable for use by a speech recognition system for recognizing spoken utterances for at least two different languages. The invention allows using a single speech recognition unit with a single speech model set to perform speech recognition on utterances from two or more languages. The method and apparatus make use of a group of a group of acoustic sub-word units comprised of a first subgroup of acoustic sub-word units associated to a first language and a second subgroup of acoustic sub-word units associated to a second language where the first subgroup and the second subgroup share at least one common acoustic sub-word unit. The method and apparatus also make use of a plurality of letter to acoustic sub-word unit rules sets, each letter to acoustic sub-word unit rules set being associated to a different language. A set of untrained speech models is trained on the basis of a training set comprising speech tokens and their associated labels in combination with the group of acoustic sub-word units and the plurality of letter to acoustic sub-word unit rules sets. The invention also provides a computer readable storage medium comprising a program element for implementing the method for training a multilingual speech model set.

Watermarking scheme for image authentication

A digital watermarking process whereby an invisible watermark inserted into a host image is utilized to determine whether or not the image has been altered and, if so, where in the image such alteration occurred. The watermarking method includes the steps of providing a look-up table containing a plurality of coefficients and corresponding values; transforming the image into a plurality of blocks, wherein each block contains coefficients matching coefficients in the look-up table; and embedding the watermark in the image by performing the following substeps for at least some of the blocks: First, a coefficient is selected for insertion of a marking value representative of a corresponding portion of the watermark. Next, the value of the selected coefficient to used to identify a corresponding value in the look-up table. Finally, the identified coefficient is left unchanged if the corresponding value is the same as the marking value, and is changed if the corresponding value is different from the marking value. After the insertion of the watermark, the image may be stored in a lossy-compression form, thus permitting efficient storage and distribution. Moreover, the method may be used to produce two output signals for authentication: (1) a meaningful pattern to facilitate a quick visual check, and (2) an additional signal to detect unauthorized alteration. The method can be applied to an image compressed using JPEG or other techniques, such as Wavelet compression, and the marked image can be kept in the compressed format. Any alteration made on the marked image can be localized, making the method suitable for use in a "trustworthy" digital camera or camcorder.

Fully-automatic mahjong machine

The invention relates to a fully-automatic mahjong machine comprising a board sending system, a board loading system, a board lifting system and a large shuffling disc. The board sending system comprises four board sending mechanisms, each board sending mechanism comprises a transmission rack, and a board sending motor, a board absorbing wheel, a transmission belt, a transmission platform, a board inlet guiding piece and a board outlet guiding piece fixed on the transmission rack; a board sending channel is arranged at the upper end of the transmission platform, the board absorbing wheel is tightly attached at the lower end of a board inlet opening of the board sending channel, the board inlet guiding piece is positioned above the board absorbing wheel, the board outlet guiding piece is positioned at a board outlet opening of the board inlet channel, the board sending motor is used for driving a motor guiding wheel, the motor guiding wheel is positioned below the transmission platform, and the transmission belt loops the motor guiding wheel, the board absorbing wheel and the transmission platform. In the invention, for the mahjong boards with different widths, the board sending mechanism of the mahjong machine can run normally by only replacing the corresponding board inlet guiding piece and the board outlet guiding piece, and a transmission rack cover does not need to be changed, so that the operation is simple and convenient, and the board inlet guiding piece and the board outlet guiding piece has extremely low production cost relative to the transmission rack cover.
