MooreSpeechCorpora collects publicly available Mooré speech, aligned with its text, for speech recognition and text-to-speech research. This version holds tales, riddles, proverbs and the Bible. Requests are reviewed by hand, usually within a few days. The recordings come from third-party publications: Mooré oral literature (mooreburkina.com and its ipsapps pages, published by Urs Niggli) and the Mooré Bible on bible.com (text © Bible Society of Burkina Faso). They are shared for non-commercial research only and remain the property of their owners. License: CC BY-NC 4.0 for our annotations only; the audio and texts stay the property of their owners.

MooreSpeechCorpora

Publicly available Mooré speech, aligned with its text, for speech recognition and text-to-speech.

En bref. Parole en mooré disponible publiquement, découpée en phrases et alignée avec son texte : contes, devinettes et proverbes (7,7 h) et la Bible de bible.com (74 h). Accès sur demande, pour la recherche non commerciale. Version plus propre : MooreSpeechCorporaV2.

MooreSpeechCorpora collects publicly available Mooré (ISO 639-3 mos) speech, cut into sentences and paired with its text. This first version joins our three earlier datasets of read tales, riddles and proverbs, and adds the Mooré Bible from bible.com. It was built with FasoSpeechCorpora, which now also covers Dioula, Fulfuldé and Gourmantchéma.

For text-to-speech, use MooreSpeechCorporaV2: the same recordings with music trimmed and every transcript checked.

Access is gated and requests are reviewed by hand. Collecting and cleaning Mooré speech takes a lot of time and resources, and we do it mostly out of passion. Please read this card, its terms and licenses before requesting access, and make sure you understand them. Respecting them keeps this work useful to the community and helps move our local languages forward. Anonymous or vague requests will not be approved.

tales = load_dataset("anyantudre/MooreSpeechCorpora", "contes", split="vol3")       # one subset, one volume
proverbs = load_dataset("anyantudre/MooreSpeechCorpora", "proverbes", split="vol10")

`contes`, `devinettes`	`audio`, `transcription`, `duration`, `chapter` (book, chapter and page), `voice`; `devinettes` also has `speaker_id`

We thank Urs Niggli, the authors and the readers for making Mooré oral literature available online.

How it was built

Each book's audio and text were downloaded, converted to 16 kHz mono and cut into sentences by forced alignment (fairseq MMS, now the fairseq backend of FasoSpeechCorpora). For default, the Mooré clips were denoised with Resemble Enhance (notebook) and speakers were labelled.

In November 2026 the three earlier datasets became subsets, and contes and proverbes got a voice column (one reader per book; V1 labels and V2 voice embeddings agree). default lost 515 proverb clips held twice (vol10 and vol11) and gained category. The bible.com part of anyantudre/moore-speech-bible was copied in unchanged as bible.

Limits

Music: many clips keep a few seconds of music at the edges; riddles start with 3 to 9 s of jingle. V2 trims them.
Alignment: contes vol5 is misaligned (clips often hold the end of the previous sentence; 400 are under 0.5 s). It stays in contes for reference only.
Transcripts: some have split words, stray hyphens, leading numbers or a proverb written twice.
Speakers: speaker_id 1 groups two men (the tales vol2 reader and the proverbs vol1 to vol8 reader); 2 is one woman. Not checked by ear.
devinettes vol9 holds proverbs, not riddles; default labels them proverbe.
Bible: not trimmed, checked or denoised. 406 clips are over 20 s (up to 86 s), 38 are under 0.5 s and 1,970 texts appear more than once. Religious language only.
Content: read speech only, no conversation.
Benchmark overlap: the bible subset contains the bible.com MPBU translation (Old Testament) of 60 of the 84 chapters held out by the Mooré speech benchmark (moore-tts-bench, to become goaicorp/MooreSpeechBench): 16 of 21 dev, 18 of 23 test and 26 of 40 test_unseen chapters, in other wording (3,298 clips, 4.17 h). The dataset has no jw.org audio or text, so none of the benchmark's jw.org test sentences. The benchmark's MPBU (bsoc) dev and test sets are about 98% contained here, so they are not valid tests for models trained on it. A model trained on bible should say on its card that it has heard the MPBU translation of most moore-tts-bench held-out Old Testament chapters.
