Publications on speech, translation, and African language AI.

Our research write-ups on automatic speech recognition, neural text-to-speech, and machine translation for low-resource African languages — along with the data pipeline that makes them possible.

Data pipeline

From raw speech and text to usable training data.

Every model begins with a pipeline that is designed to be repeatable, transparent, and practical for low-resource languages. The process spans collection, cleaning, annotation, evaluation, and release.

01

Data collection

Voice and text data are gathered from native speakers, public sources, and curated multilingual content to build a broad and representative foundation.

02

Curation and cleaning

Audio is normalized, segmented, and quality-checked while text is standardized and aligned to reduce noise and improve learning quality.

03

Annotation and alignment

Transcripts, translations, and metadata are verified so the data is reliable enough for training and evaluation.

04

Training and evaluation

Models are fine-tuned, validated, and benchmarked with both automated metrics and human review to measure real-world usefulness.

05

Release and iteration

The best-performing models and datasets are packaged for reuse, while feedback from deployment helps shape the next iteration.

Publications
