Free Spoken Digit Dataset (FSDD)

A simple audio/speech dataset consisting of recordings of spoken digits in wav files at 8kHz. The recordings are trimmed so that they have near minimal silence at the beginnings and ends.

FSDD is an open dataset, which means it will grow overtime as data is contributed. Thus in order to enable reproducibility and accurate citation in scientific journals the dataset is versioned using git tags.

Current status

  • 2 speakers
  • 1,000 recordings (50 of each digit)
  • English pronunciations

Organization

Files are named in the following format: {digitLabel}_{speakerName}_{index}.wav Example: 7_jackson_32.wav

Metadata

metadata.py contains meta-data regarding the speakers gender and accents.

Included utilities

trimmer.py Trims silences at beginning and end of an audio file. Splits an audio file into multiple audio files by periods of silence.

fsdd.py A simple class that provides an easy to use API to access the data.

spectogramer.py Used for creating spectrograms of the audio data. Spectrograms are often a useful pre-processing step.

Usage

The test set officially consists of the first 10% of the recordings. Recordings numbered 0-4 (inclusive) are in the test and 5-49 are in the training set.

Contributions

Please contribute your homemade recordings. All recordings should be 8kHz wav files and be trimmed to have minimal silence. Don't forget to update metadata.py with the speaker meta-data.
