Hausa Read Speech Dataset
Hausa read speech sourced to your specification — no inventory, no fixed listing. This page covers what is specifically hard about this pairing, and which fields your specification needs to pin down.
Why read speech in Hausa is its own problem
Hausa read speech is a good technical fit: the language has a settled written standard and speakers read it comfortably. The complication is variety. The standard text is Kano-based, and readers from Sokoto, Katsina, or Niger read the same passage with their own tone and length realizations, so the acoustics differ although the text is identical. Which realization a batch contains has to be known, and plain Boko gives no ground truth for tone or length in the text itself.
The field to pin down first: Annotate the reader's variety per record and deliver in batches by variety; and decide whether the reading text ships with tone and vowel-length marking, since plain Boko leaves both entirely to the reader.

What read speech data is
Recordings of speakers reading specified text, with clear pronunciation and known text, the base material for TTS and ASR.
What buyers get wrong about it
The trap with read speech is that it is too clean — it comes out sounding like a news anchor, and a model trained on it underperforms in real conditions. We collect an extra set at natural speaking rate as a comparison.
The specification field that decides the quote
Studio (low noise floor) or home (real environment) — the two differ in both signal-to-noise ratio and price.
The language side: what Hausa demands
Hausa is written in two scripts at once: Latin (Boko) dominates, while Arabic script (Ajami) is used in religious contexts. Running both in parallel means the script-to-speech mapping has to be defined separately for each.
What we can put in this delivery
-
Read and conversational speech
Scripted recording for TTS, and unscripted conversation for recognition. Specified separately because they need different speaker pools.
-
Transcription to your convention
Orthographic or phonetic, with the guideline written before production and shared with you for review.
-
Speaker metadata
Age band, gender, region and dialect background per file, so you can slice the dataset rather than take it whole.
-
Consent documentation
Signed speaker consent covering the intended use, plus collection methodology and the annotation guideline.
-
Pilot batch
A small batch first, which you can reject. Misalignments surface after a few hours rather than at delivery.
-
Delivery in your format
Audio format, sampling rate, segmentation length and metadata schema set to your pipeline's requirements.
What arrives in a delivery
| Component | What it is |
|---|---|
| Audio files | Format, sampling rate and segmentation length set to your pipeline. Named to a convention you specify. |
| Transcription | Orthographic or phonetic, produced under a guideline you review before production starts. |
| Speaker metadata | Age band, gender, region and dialect background per file, plus a speaker identifier so the dataset can be sliced. |
| Recording conditions | Environment, device and, where relevant, measured signal-to-noise ratio per file. |
| Annotation guideline | The document the annotators worked from, so you can reproduce the conventions on your own data. |
| Consent records | Signed speaker consent covering your intended use, with the transfer mechanism addressed where required. |
| Collection methodology | How speakers were recruited, screened and scheduled — the part that tells you how biased the pool is. |
| Quality report | Pilot outcome, re-work log, and the annotator agreement figures where the task supports measuring them. |
Questions we get about Hausa Read Speech
How many distinct speakers can you provide for Hausa Read Speech?
It depends on the specification and the timeline, and we will give a real number rather than a target. For this pairing, speaker recruitment is usually the step that sets the schedule. Annotate the reader's variety per record and deliver in batches by variety; and decide whether the reading text ships with tone and vowel-length marking, since plain Boko leaves both entirely to the reader.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. Hausa read speech is a good technical fit: the language has a settled written standard and speakers read it comfortably. That is exactly the kind of decision a default guideline leaves open, and it is where annotators diverge. Send us your guideline, or we will draft one and you can review it before production starts.
Do you offer a sample before we commit to a full run?
Yes. Select a free sample in the request form and describe what you need. A pilot batch is the cheapest way to establish whether the quality bar is reachable for Hausa Read Speech before committing to the full volume.
Is the data licensed or owned outright?
Licensing terms are set per project, so tell us how the model will be used and whether it will be distributed. Consent documentation travels with the data either way, and we do not handle medical or clinical data or recorded telephone calls.
