Hausa Call Center Speech Dataset
Hausa call center 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 call center speech in Hausa is its own problem
Hausa is the trade language of much of West Africa, so a call center in Kano is not a monolingual operation: the agent may be a first-language speaker while the caller answers in second-language Hausa shaped by Fulfulde, Kanuri, or Yoruba, or the reverse. Second-language Hausa carries substrate phonology that is systematic rather than random noise. Both sides of the call therefore need their own language background recorded, or one batch mixes two different sound systems under a single label.
The field to pin down first: Every speaker's first language and Hausa variety (Kano, Sokoto, Katsina, or a Nigerien variety) has to be annotated per speaker rather than per call; first- and second-language Hausa in one batch cannot be separated afterwards.

What call center speech data is
Recorded customer-service calls, real or simulated, capturing both the agent and the caller side, used for call center QC, intent recognition, and dialogue systems.
What buyers get wrong about it
Compliance is what buyers fear most — call recordings involve personal data and recording consent, and the source has to be able to produce a consent provenance. This is also why we only do simulated collection and never work from intercepted real calls.
The specification field that decides the quote
Two-channel separated (agent and caller on separate tracks) or single-channel mixed — this directly determines how the data is annotated and how models are trained on it, and it has to be decided when the order is placed.
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 Call Center Speech
How many distinct speakers can you provide for Hausa Call Center 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. Every speaker's first language and Hausa variety (Kano, Sokoto, Katsina, or a Nigerien variety) has to be annotated per speaker rather than per call; first- and second-language Hausa in one batch cannot be separated afterwards.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. Hausa is the trade language of much of West Africa, so a call center in Kano is not a monolingual operation: the agent may be a first-language speaker while the caller answers in second-language Hausa shaped by Fulfulde, Kanuri, or Yoruba, or the reverse. 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 Call Center 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.
