Hausa (ha) · Lagos, recording to order

Where it is spoken

Hausa at a glance.

Spoken across northern Nigeria (Kano, Kaduna, Katsina, Sokoto and beyond) and in Niger, Ghana and other West African countries, as a first language and as a widely used trade language.

Code
ha (ISO 639-1)
Script
Latin (Boko) with hooked letters ɓ, ɗ, ƙ and ʼy; Arabic-based Ajami exists and can be discussed
Tone and length
Hausa marks tone and vowel length in teaching texts but rarely in everyday writing; we add them on request
Dialects
Standard (Kano-based) Hausa by default; other regional varieties tagged when you need them
Why it is hard for models

What speech models get wrong.

Hooked letters

ɓ, ɗ and ƙ are often typed as b, d and k online, so clean transcripts with the right letters are scarce.

Tone and vowel length

Both carry meaning but are rarely written, which makes text-to-speech and pronunciation hard.

Arabic and English loanwords

Everyday Hausa borrows from Arabic and English; transcription guides must handle both.

ASR and TTS

Read prompts or conversation? Usually both.

For speech recognition (ASR)

For ASR we record many speakers on read prompts and conversation, transcribed with the hooked letters so your text normaliser has clean targets.

For text-to-speech (TTS)

For TTS we record a few speakers for longer from a balanced prompt list, with tone and length marked on request, and voice-synthesis consent named explicitly.

Speaker diversity

A fair mix of real speakers.

  • Speakers by region of origin, age band and gender to a quota you set
  • Lagos-based Hausa speakers first; northern cities such as Kano are on our next list
  • Every speaker ID-checked so one voice is one person
  • Market, transport, farming, family and service topics

Questions

Buyers usually ask.

Can you transcribe in Ajami (Arabic script)?

Our default is Latin (Boko) spelling with hooked letters. Ajami transcription can be scoped per order if you need it.

Are speakers recorded in northern Nigeria?

Today our speakers are in Lagos, which has a large Hausa-speaking community. Kano is on our list of next cities, opened when buyer orders need it.

How do I order Hausa speech data?

Email [email protected] or use the request form with the hours, read/conversation split, speaker mix and transcript rules you need. We record a free sample of about 10 hours to your spec first. Pricing is quoted per approved hour after scoping.

How do speakers consent?

Each speaker passes an ID check and records consent in their own language before any paid task. If the data will be used for voice synthesis (TTS), that use is named explicitly. Speakers can withdraw from future deliveries.
