AI Technical Summary

Technical Problem

Existing in-vehicle speech recognition technologies lack accuracy and robustness in complex acoustic environments, especially in in-vehicle scenarios where noise is complex and reverberation is significant. Existing spiking neural networks consume a lot of memory during training and lack targeted adaptation.

Method used

We employ a spiking neural network based on reparameterized spiking convolutional self-attention, combined with a multi-level spiking convolutional encoder, a Transformer decoder, and a CTC-assisted classification branch. Through in-vehicle voice data preprocessing, feature extraction, and absolute position encoding, we construct a speech recognition method for in-vehicle scenarios, reducing memory usage during training and enhancing the ability to extract local information.

Benefits of technology

It improves the accuracy and environmental robustness of in-vehicle speech recognition, reduces training costs and computational load, and is suitable for efficient in-vehicle applications.
