Keyword spotting

This is a prebuilt dataset for a keyword spotting system based on a subset of data in the Google Speech Commands Dataset, with added noise from the Microsoft Scalable Noisy Speech Dataset. It contains 25 minutes of data per class, split up in 1 second windows, sampled at 16,000Hz. The dataset contains:

  • Yes - one second samples with only the word "yes" in it.

  • No - one second samples with only the word "no" in it.

  • Unknown - one second samples of other words.

  • Noise - one second samples of background or static noise.
