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 over time as data is contributed. In order to enable reproducibility and accurate citation the dataset is versioned using Zenodo DOI as well as git tags.
Current status
- 6 speakers
- 3,000 recordings (50 of each digit per speaker)
- English pronunciations
Organization
Files are named in the following format:
{digitLabel}_{speakerName}_{index}.wav
Example: 7_jackson_32.wav
Contributions
Please contribute your homemade recordings. All recordings should be mono 8kHz wav files and be trimmed to have minimal silence. Don't forget to update metadata.py with the speaker meta-data.
To add your data, follow the recording instructions in acquire_data/say_numbers_prompt.py
and then run split_and_label_numbers.py to make your files.
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.
