3results about How to "Reduce false wake-up rate" patented technology

The invention relates to an equipment awakening method and device, computer equipment and a storage medium. The method comprises the following steps: in response to a voice signal collected by a target terminal, performing voice recognition processing on the voice signal according to different segmented words and the segmented word weight of each segmented word to obtain a recognition result; wherein the different slice segmented words are obtained by performing slice splitting on the user-defined wake-up word; and in response to the recognition result and the self-defined wake-up word, determining that the voice signal meets a wake-up condition, and waking up the target terminal. By adopting the method, the awakening accuracy can be improved.

The invention discloses a low-delay streaming voice wake-up method and device for an embedded terminal, is applied to the technical field of data processing, and adopts a GRU as a backbone architecture for the requirements of low power consumption and high real-time performance of voice wake-up of the embedded terminal. The original audio is segmented and reconstructed through time domain lightweight preprocessing, and the FFT overhead is eliminated through linear layer mapping; building a multi-layer GRU full-causal streaming coding network, wherein no sliding window cache exists, and the memory bandwidth occupies O (1); outputting Token probability distribution containing Blank through a CTCLoss training module, and directionally extracting a target Token probability; constructing a target index sequence based on the target wake-up word and a CTC protocol, and setting three types of state transition rules to generate anti-interference decoding information; and a non-Top-K pruning decoding mechanism is adopted, an attenuation factor and threshold judgment is combined, a judgment result with constant calculation complexity and low false and missing wakeup is generated, and subsequent interaction is triggered if the judgment result succeeds.

This disclosure relates to a device control method, apparatus, device, and readable storage medium, and pertains to the field of intelligent voice technology. It includes: acquiring audio to be recognized, the audio containing voice information; recognizing the audio based on a preset wake-up word recognition model to determine whether the audio contains a preset wake-up word; if the audio contains the preset wake-up word, controlling the device to enter a wake-up state; otherwise, controlling the device to remain in a non-wake-up state. Using the device control method proposed in this disclosure, preset wake-up words and non-preset wake-up words can be accurately distinguished, thereby reducing the false wake-up rate of the device.
