4results 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.

The application discloses a voice wake-up processing method and device, a storage medium and electronic equipment, and relates to the technical field of audio processing. The method comprises the following steps: obtaining a to-be-processed voice signal; performing adaptive filtering echo cancellation processing on the to-be-processed voice signal to obtain an error signal; performing echo cancellation nonlinear post-processing on the basis of a post-processing input signal and the to-be-processed voice signal by using a nonlinear post-processing network to obtain an echo cancellation signal; and performing wake-up detection processing on the basis of the echo cancellation signal by using a wake-up network. The nonlinear post-processing network and the wake-up network are obtained through joint adversarial training. In the adversarial training, the nonlinear post-processing network acts as a generator and the wake-up network acts as a discriminator. The goal of the adversarial training is to make the accuracy of the discriminator in identifying the authenticity of the data generated by the generator higher and higher. The application can enhance the wake-up rate while reducing the false wake-up rate caused by the wake-up processing procedure itself.

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.
