  • Publication number: 20180336883
    Abstract: Embodiments of the present disclosure provide a language recognition method and apparatus, a device and a computer storage medium. In an aspect, in the embodiments of the present disclosure, after the Nth speech segment included by the speech signal is received, language recognition is performed according to already-received previous N speech segments to obtain the score of each language in at least one language, N being 2, 3, 4 . . . ; therefore, if there exists a langue whose score reaches the designated threshold, the language whose score reaches the designated threshold is considered as the language matched with the speech signal. Therefore, the technical solutions according to embodiments of the present disclosure solve the problem in the prior art that the efficiency of language recognition is lower so that the language recognition cannot be applied to an application scenario in which the recognition result needs to be obtained quickly.

  • Patent number: 8546503
    Abstract: This invention deals with an approach to control anionic polymerization. The anionic polymerization is conducted by adding a kind of initiator ligand compound, directly or in the form of solution into the monomer or initiator at the same or different time, or at different stages. The metal atoms in the ligand can form the association with the initiator cations, while the alkyloxy groups in the initiator ligand can restrict the entering channel of the addition of the monomers due to their relatively large volume or steric hindrance. Therefore, the initiator ligand compound can restrict the rate of anionic polymerization, restrain the side reaction, and make the anionic polymerization possible to be conducted at room or even higher temperature. The molar ratio of initiator ligand compound to initiator is from 0.01:1 to 20:1.

  • Patent number: 8125970
    Abstract: A ranging method is described for measuring distance between a central node and an equipment node in a beacon wireless personal area network. At the beginning stage, the central node calculates the parameters needed in the ranging operation and sends these parameters to the equipment nodes by beacon frames. Equipment nodes, in turn, send ranging frames at time slots assigned thereto according to the information received in the beacon frames. The central node calculates beacon frame flight time by recording the sending time and the arrival time of the ranging frame, and then calculates the distance between the central node and the equipment node. For nodes failing in the ranging procedure, the ranging parameters are changed according to failing reasons and the above procedure is repeated until a ranging result is received without failure.
