Natural Language Processing (NLP) has seen significant progress in English and other widely spoken languages, but its application to African languages remains underexplored. In Ghana, where multiple indigenous languages are spoken, NLP techniques can offer valuable applications such as language translation, text summarization, and sentiment analysis. The research will employ state-of-the-art machine learning algorithms specifically tailored for African language datasets. A comparative analysis will be conducted using various NLP techniques to assess which methods yield the best results across different languages and domains. Initial experiments indicate that transfer learning models, such as BERT adapted to local language corpora, show promising performance in text classification tasks with an accuracy of around 85% on average. However, there is significant variability depending on the specific language and domain. Despite current challenges, including limited datasets and varying linguistic structures, NLP for African languages holds substantial potential for innovation and socio-economic impact in Ghana. Future work should focus on expanding model training efforts to cover more languages and domains. Investment is needed in both data collection and research methodologies to support the development of robust NLP systems for African languages. Collaboration between academia, industry, and government can accelerate this process. Model estimation used =argmin_ᵢ (yᵢ, f_ (xᵢ) ) +₂², with performance evaluated using out-of-sample error.
