What I'm looking for

I’m looking for remote work where I can review and edit Swahili/English transcripts, verify timestamps and segmentation, and deliver high-accuracy speech-to-text datasets with clear QA standards and reliable turnaround expectations.

I’m a detail-oriented Transcription Specialist and AI Data Annotation Specialist with strong proficiency in Swahili and English, supported by academic training in Linguistics, Media and Communication from the University of Nairobi. I review audio recordings, refine machine-generated transcripts, and ensure high-quality speech datasets for AI model development.

I focus on phonetics, language structure, transcript editing, and speech recognition data quality assurance—especially punctuation, grammar, speaker distinction, and contextual corrections. In my freelance work, I verified audio segmentation and timestamps to keep transcripts precisely aligned with spoken content.

I also bring disciplined remote-work execution, including reliable productivity, strong time management, and consistent quality benchmarks. Recently, I achieved 98% transcription accuracy while meeting strict project standards, and I previously reduced documentation errors by 30% through thorough quality reviews.
