Moore Speech Corpora: A Cleaned, Denoised Audio-Text Dataset for Mooré TTS and ASR

The Moore Speech Corpora is a collection of aligned audio and text in Mooré, gathered from publicly available sources. This unified corpus is curated for research and academic purposes in low-resource speech and language processing, especially for text-to-speech (TTS) and automatic speech recognition (ASR) in the Mooré language (ISO 639-3: mos).

Mooré is under-represented in current speech corpora and technologies. Our mission is to make AI accessible to all communities. By open-sourcing this dataset and its associated tools, we aim to promote and preserve our national languages through practical speech-technology resources.

Currently this version of the dataset is a merged, denoised, and ready-to-use audio-text corpus built from:

We're still working to add other sources.

⚠️ Access is gated. To request access, please read the policy below.
🚩 TLDR: Anonymous or vague requests will not be approved.

All scripts used to prepare this dataset are part of the Moore Speech Corpora Toolkit. ⭐ if it’s helpful!


Dataset Structure

Each record contains:

  • audio: Original 16 kHz WAV audio (raw)
  • denoised_audio: Denoised 16 kHz WAV audio (cleaned from background music)
  • text: Transcription in Mooré
  • duration: Duration in seconds
  • voice: Voice label if known
  • speaker_id: Unique speaker identifier

Example format:

{
  "text": "M ba Soaamb da mi n kėnd n tãooda ware...",
  "duration": 4.85,
  "voice": "female",
  "speaker_id": "2",
  "audio": { "path": "...", "array": [...], "sampling_rate": 16000 },
  "denoised_audio": { "path": "...", "array": [...], "sampling_rate": 16000 }
}
