AI Technical Summary
Technical Problem
Existing voice wakeup systems in electronic devices suffer from poor performance in complex acoustic environments, particularly with background noise, multi-sound source interference, and far-field echoes, leading to low wakeup rates and high false wakeups.
Method used
A two-stage separation and wakeup solution is implemented, where a first-stage streaming process uses a neural network to separate and determine potential wakeups, followed by a second-stage offline process to confirm and reduce false wakeups, employing dpconformer network structures for both stages.
Benefits of technology
This approach significantly enhances wakeup rates while minimizing false wakeups, ensuring reliable voice interaction in challenging acoustic conditions.
