摘要： An accurate speech recognition system capable of rapidly processing greater varieties of words and operable in many different devices, but without the computational power and memory requirements, high power consumption, complex operating system, high costs, and weight of traditional systems. The utilization of individual letter utterances to transmit words allows voice information transfer for both person-to-person and person-to-machine communication for mobile phones, PDAs, and other communication devices. This invention is an apparatus and method for a speech recognition system comprising a microphone, front-end signal processor for generating parametric representations of speech input signals, a pronunciation database, a letter similarity comparator for comparing the parametric representation of the input signals with the parametric representations of letter pronunciations, and generating a sequence of associations between the input speech and the letters in the pronunciation database, a vocabulary database, a word similarity comparator for comparing an aggregated plurality of the letters with the words in the vocabulary database and generating a sequence of associations between them, and a display for displaying the selected letters and words for confirmation.

摘要： A sigma-delta modulated discrete time oscillator. The sigma-delta modulated discrete time oscillator comprises a synchronous counter and a sigma-delta modulator. The sigma-delta modulator operating in a first clock receives a control signal to generate a divider pattern output. The control signal provides a DC value for the frequency of the first clock. The divider pattern comprises a plurality of numbers, values of which are synchronous with the rate of the first clock. The synchronous counter operates in a second clock. In the synchronous counter, the second clock is divided by the divider pattern to generate the first clock. The frequency of the second clock is much higher than the frequency of the first clock.

摘要： A multi-modulus divider includes a chain of n dual modulus divider cells in cascade and connected in a ripple configuration where the last (n-k) of the divider cells are state-parked dual modulus divider cells. The state-parked dual modulus divider cells are forced to a given logical state when the divider cell is bypassed. The state-parked dual modulus divider cells ensure that the multi-modulus divider can change between different number of cells without clock glitches or clock errors. The multi-modulus divider is therefore capable of achieving a wide division range with seamless transition between division ratios.
