SpeechCommandsDataset

burn_core::data::dataset::audio

Struct SpeechCommandsDataset 

Source 
pub struct SpeechCommandsDataset { /* private fields */ }
Available on crate features std and dataset and audio only.
Expand description

Speech Commands dataset from Huggingface v0.02. See Speech Commands dataset.

The data is downloaded from Huggingface and stored in a SQLite database (3.0 GB). The dataset contains 99,720 audio samples of 2,607 people saying 35 different words.

NOTE: The most samples are under 1 second long but there are some with pure background noise that need splitting into shorter segmants.

The labels are 20 target words, silence and other words.

The dataset is split into 3 parts:

  • train: 84,848 audio files
  • test: 4,890 audio files
  • validation: 9,982 audio files
