  • Application level SD card space management
    Patent number: 11726682
    Abstract: An apparatus includes a removable media interface circuit and a processor. The removable media interface may be configured to read and write files to a non-volatile storage medium. The processor may be configured to generate encoded data and manage file operations involving storing the encoded data on the non-volatile storage medium to minimize a number of file fragments.
    Type: Grant

  • Electrolaryngeal speech reconstruction method and system thereof
    Patent number: 8650027
    Abstract: The invention provides an electrolaryngeal speech reconstruction method and a system thereof. Firstly, model parameters are extracted from the collected speech as a parameter library, then facial images of a speaker are acquired and then transmitted to an image analyzing and processing module to obtain the voice onset and offset times and the vowel classes, then a waveform of a voice source is synthesized by a voice source synthesis module, finally, the waveform of the above voice source is output by an electrolarynx vibration output module, wherein the voice source synthesis module firstly sets the model parameters of a glottal voice source so as to synthesize the waveform of the glottal voice source, and then a waveguide model is used to simulate sound transmission in a vocal tract and select shape parameters of the vocal tract according to the vowel classes.
