Wilson Ogero

I’m a detail-oriented linguistic specialist with 5+ years of experience in audio evaluation, transcription, and data annotation for AI and speech recognition systems. I specialize in assessing English audio quality, transcription accuracy, and linguistic consistency, while maintaining over 95% accuracy. I bring a strong quality-first mindset to every dataset I touch.

At Samasource Kenya, I evaluated audio datasets for speech models by reviewing English/Swahili transcriptions and flagging audio quality issues. I focus on precision in transcription review and linguistic QA so the labels remain consistent and usable for model training. My work supports better downstream performance by keeping the dataset dependable.

Previously at Digital Divide Data, I transcribed and reviewed audio clips and annotated datasets for ML. I enjoy the combination of linguistic judgment and structured QA, especially when it directly improves training data quality for speech recognition. I’m also pursuing a diploma in data science to deepen my analytics and data-driven impact.
