Wake-up word detection method, electronic device, and storage medium

An electronic device, comprising:

• a processor;
• and
• a memory, configured to store instructions executable by the processor,
• wherein the processor is configured to read the instructions from the memory and execute the instructions to implement a wake-up word detection method, and the wake-up word detection method comprises:
• acquiring audio data and at least one wake-up word;
• inputting the audio data and the at least one wake-up word into a wake-up word detection model to output a frame-level detection probability of the audio data for the at least one wake-up word, wherein the wake-up word detection model is determined through stage-wise training using a positive and negative sample dataset constructed based on the at least one wake-up word;
• and
• determining, based on the frame-level detection probability, a wake-up word detection result of the audio data for the at least one wake-up word.

A non-transitory computer-readable storage medium, storing a computer program, wherein the computer program is configured to perform a wake-up word detection method, and the wake-up word detection method comprises:

• acquiring audio data and at least one wake-up word;
• inputting the audio data and the at least one wake-up word into a wake-up word detection model to output a frame-level detection probability of the audio data for the at least one wake-up word, wherein the wake-up word detection model is determined through stage-wise training using a positive and negative sample dataset constructed based on the at least one wake-up word;
• and
• determining, based on the frame-level detection probability, a wake-up word detection result of the audio data for the at least one wake-up word.
