Faso Speech Dioula Digits

A spoken-digit classification dataset in Dioula (Jula/Bambara), built from the Zenodo record 8320370 archive (DOI: 10.5281/zenodo.8320370).

Each clip is one speaker saying a single digit, 1 through 4, in Dioula. Recordings vary in speaker, accent, and recording environment.

Dataset Summary

Split	Rows	Duration	Per-class rows
train	1,532	01:34:14.9	383 / 383 / 383 / 383
validation	168	00:10:08.2	42 / 42 / 42 / 42

The split is a deterministic, per-class 90/10 hold-out (seed 42), so both splits have an even class balance across digits 1-4.

Data Fields

Column	Description
audio	Embedded Hugging Face Audio(decode=False) value with bytes and path
text	The spoken digit as a string ("1"-"4")
label	The spoken digit as a ClassLabel (0-3, names "1"-"4")
language	dyu
duration	Clip duration in seconds
id	Stable identifier, dioula-digits:Class_<n>/<original_file_stem>

Usage

from datasets import Audio, load_dataset

ds = load_dataset("madoss/faso-speech-dioula-digits")
ds = ds.cast_column("audio", Audio(decode=False))

print(ds["train"][0]["text"], ds["train"][0]["label"])
print(ds["train"][0]["audio"])

Source Data

Original archive: AudiosDioula.zip, four folders Class_1-Class_4, one .wav file per recording, no changes made to the audio itself. Rows were grouped by folder into label/text.

Per the source README, the data was collected for the research project "Setting up a speech recognition model for under-resourced languages", targeting a Dioula digit-recognition model.
