01 · Speech recognition

AI research & robotics lab

We teach machines
to hear.

Neriqlabs builds speech, language and perception models, and the robots and sensors that use them. We start where the world's training data runs out: Ghanaian languages, African environments, and machines that have to work outside the lab.

Language AI · the gap

The global AI stack works in about twelve languages. Seven thousand are spoken on Earth.

We went through the documentation of sixteen commercial speech vendors. Not one lists Akan, Twi, Ewe, Ga or Dagbani. So a Ghanaian bank that wants to answer calls by voice has two options: an English-only phone menu many of its customers cannot use, or more human agents. The missing piece is data, and then models trained on it.

What we have built

Three models that make one phone call work.

Speech recognition

TubaSTT

It hears Twi on a bad phone line.

Fine-tuned from w2v-BERT 2.0 with a character-level CTC head, trained with 8 kHz phone-codec augmentation so it survives a real call rather than a studio recording. Bilingual Twi and English, and it keeps up when a caller switches between them.

Speech synthesis

Kasanoma

It answers in Twi, and switches mid-sentence.

Built on the CosyVoice3 backbone and fine-tuned on restored Asante Twi speech. As far as our survey of sixteen vendors goes, it is the only released system that moves between Twi and English inside a single sentence, which is how people actually speak.

Language model

TubaBrain

It understands what the caller wants.

A Qwen3.5-9B fine-tune for Twi customer-service dialogue and tool calling: balance checks, transfers, account problems. Scale alone does not fix this. A 27B model zero-shot scores 9 to 10 out of 10 on English tool calls and falls into repetition loops in Twi.

Lower word error rate is better. These are development-set figures: a speaker-disjoint held-out test set is still being built, and we will publish it alongside the next release rather than quote a number nobody else can reproduce.

Robotics

Intelligence that leaves the screen.

Language was our first problem, not our only one. The same gap runs through the physical world: robots and sensors are trained on data from a handful of places and break when they leave them. Our robotics work is perception, state estimation and autonomy for machines that have to work outdoors, at night, in wind and in noise, on hardware cheap enough to deploy.

Perception

Sensor fusion

Cameras, microphone arrays and radio receivers read the same scene. We fuse them into one picture, so a machine is not blind the moment one sensor is.

Estimation

Tracking and localisation

Kalman filtering, multi-target tracking and triangulation from bearings: the maths that turns noisy readings into a position you can act on.

Hardware

Edge devices

Compact compute nodes on single-board computers with AI accelerators, in enclosures we design in CAD and print ourselves. Models run where the sensor is.

Learning

Robot data

Trajectory labelling, success checks, simulated environments and evaluation for robot learning, with the same paid, audited pipeline we use for speech.

Project · Stillsky

Ground sensor posts and tracking software that find the drones radio detectors miss.

Read about it

How it works

Two engines that need each other. Models without the right data are deaf and blind; data without models stays unread.

Engine 01 · Models

Production-grade, efficient, deployable.

We design speech, language and perception models for production: small enough to run where customers and sensors are, fast enough for real conversation and real-time tracking, and built for the languages, accents and environments the largest models miss.

Engine 02 · Data

The training set that does not exist yet.

Low-resource does not only mean language. It means any data the industry never bothered to collect: a dialect, a dialling tone, a factory floor, a robot arm in a workshop in Accra. We design the collection pipelines, pay the people who produce the data, and deliver it licensed, cleaned and evaluation-graded.

Coverage

Start where the data is thinnest.

Twi first, because it is the fastest route to proof: thirty million speakers and no vendor serving them. Ga, Ewe, Dagbani and Hausa are next, and the method travels further than West Africa.

  • Ewe

Data partnerships

Tell us what you need collected.

We run collection and annotation in markets most vendors do not reach, with contributors paid per task and the licensing settled before a single file is recorded. Speech and language is where we started, not where we stop: if the data you need does not exist yet, that is the work.

  • Licensed and consented at source, with provenance you can audit
  • Native speakers and local operators, paid per task
  • Evaluation-graded, not just collected
What kind of data?

We use what you send only to reply to this enquiry.

If you are building where the global stack does not reach, talk to us.

Research groups working on African languages, robotics teams that need data from new environments, and operators in Ghana: all are the right conversation.
