Low-power-consumption whole vehicle controller integrated with gateway function

The invention discloses a low-power-consumption whole vehicle controller integrated with a gateway function. The low-power-consumption whole vehicle controller comprises a main control unit, a gatewaycommunication processing unit, an advanced power management unit, an input signal processing unit, an output processing unit, a system storage unit and a breakdown processing unit. A power supply unit supplies electricity to a storage battery, electricity is supplied to a system and a circuit on the periphery of the system by outputting stable voltage through the power supply unit, and normal working of the system is ensured. The main control unit is in data connection with the input signal processing unit, the output processing unit, the storage unit, a breakdown diagnosis unit and the gateway communication unit through a high-speed SPI communication interface, an AD port and a CAN interface, and network information interconnection of a whole vehicle CAN bus is achieved. The low-power-consumption whole vehicle controller can be applied to the situation that a main control unit with pure electric and hybrid vehicle models serving as wholes vehicles coordinates all sub-controllers to work, the new energy whole vehicle controller function is achieved functionally, the gateway function is also achieved, the number of vehicle body electronic controllers is reduced, and the vehicle body space is effectively utilized.

Phonetic-level low power consumption spoken language evaluation and defect diagnosis method without standard pronunciation

InactiveCN103985391AImprove pronunciation qualityReduce loadSpeech analysisSpoken languageFinite state
The invention discloses a phonetic-level low power consumption spoken language evaluation and defect diagnosis method without standard pronunciation. The method includes the following steps that (1) acoustic feature extraction is conducted on user pronunciation to obtain a feature vector sequence; (2) decoding operation is conducted on the feature vector sequence of user pronunciation through a Viterbi algorithm based on a weighting finite state converter Q, so that the mapping relation from the feature vector sequence to a phoneme sequence is obtained; (3) with respect to each phoneme, the pronunciation quality of the user on each phoneme is evaluated by calculating the goodness of fit between a feature vector set corresponding to the phonemes and the mathematic representation of the phonemes in an acoustic model H. The phonetic-level low power consumption spoken language evaluation and defect diagnosis method without standard pronunciation has the advantages that the method is independent of standard pronunciation, all burdensome calculations are executed on a server terminal, the calculation amount of a user terminal is minimized, the load and power consumption on the terminals are effectively reduced, in the using process of the terminals, networking is needless, and network flow consumption is avoided; the phonemes which the user cannot pronounce well can be recognized, and targeted training is provided.

Phoneme-level low-power consumption spoken language assessment and defect diagnosis method

The invention discloses a phoneme-level low-power consumption spoken language assessment and defect diagnosis method. The method comprises the steps of (1) conducting acoustic feature extraction on user pronunciation and standard pronunciation to obtain feature vector sequences; (2) decoding the feature vector sequence of the user pronunciation and the feature vector sequence of the standard pronunciation with the Viterbi algorithm based on a weighted finite state transducer Q to obtain the mapping relations between the feature vector sequences and a phoneme sequence, the alignment alpha of the user pronunciation and the alignment (as described in the specification) of the standard pronunciation; (3) comparing the alignment alpha and the feature vector sequence of the user pronunciation with the alignment (as described in the specification) and the feature vector sequence of the standard pronunciation so that user pronunciation quality can be assessed, wherein the higher the goodness of fit is, the better the pronunciation quality is. The method has the advantages that complicated operation is executed in a server, and therefore the load and power consumption of a terminal are effectively reduced; the terminal can be used without networking, and therefore network flow consumption is avoided; phonemes with pronunciation flaws can be recognized and targeted practice can be provided.
