About Me

Ghanaian AI researcher and software engineer with over five years of experience building scalable systems across eCommerce, blockchain, and AI research enablement. I have contributed to projects such as UGSpeech Data, Kasa Tutor, and TTS models focused on African languages, working at institutions like WiV Technologies, Chatdaddy, Data Intelligence and Swarm Analytics Lab, and the HCI Lab at the University of Ghana Department of Computer Science. Currently pursuing an MSc in Computer Science at the University of Ghana, I specialize in Natural Language Processing, Human-Computer Interaction, and Text-to-Speech systems for low-resource and tonal languages. I am deeply involved in academic research, speech dataset development, and community-centered AI projects. My goal is building inclusive, explainable, and culturally aware AI systems that reflect the linguistic diversity of the African continent—especially in health, education, and public service applications.

đź“š My Research

I’m a research student with the Human-Computer Interaction (HCI) group at the University of Ghana, where I focus on building speech technologies for African languages—especially Akan. My current work involves developing Text-to-Speech (TTS) system for a maternal health chatbot.

I integrate neural architectures like VITS and YourTTS, with emphasis on prosody modeling, speaker adaptation, and low-resource data strategies. I also build tools for audio segmentation, transcription, and evaluation to accelerate dataset creation and model benchmarking across diverse speakers and conditions.

Beyond technical development, I explore how inclusive NLP systems can enhance access to healthcare, education, and civic participation in underrepresented communities. If you’re working on related problems or care about making African languages more present in digital spaces, I’d love to connect.
