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.
- 6 speakers
- 3,000 recordings (50 of each digit per speaker)
- English pronunciations
Files are named in the following format:
{digitLabel}_{speakerName}_{index}.wav
Example: 7_jackson_32.wav
A simple way of using this dataset is with Activeloop's python package Hub!
First, run pip install hub (or pip3 install hub).
import hub
ds = hub.load("hub://activeloop/spoken_mnist")
# check out the first spectrogram, it's label, and who spoke it!
import matplotlib.pyplot as plt
plt.imshow(ds.spectrograms[0].numpy())
plt.title(f"{ds.speakers[0].data()} spoke {ds.labels[0].numpy()}")
plt.show()
# train a model in pytorch
for sample in ds.pytorch():
# ... model code here ...
# train a model in tensorflow
for sample in ds.tensorflow():
# ... model code here ...available tensors can be shown by printing dataset:
print(ds)
# prints: Dataset(path='hub://activeloop/spoken_mnist', tensors=['spectrograms', 'labels', 'audio', 'speakers'])For more information, check out the hub documentation.
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.py contains meta-data regarding the speakers gender and accents.
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.
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.
