A large-scale dataset of 1,740 hours (growing daily) of real online job interview video in Nigerian English, featuring natural, non-scripted interview responses recorded in Nigeria — 97,066 clips from 5,749 speakers across 6,305 interview sessions across Lagos, Abuja, Port Harcourt, Ibadan and further Nigerian cities.
All participants explicitly opt in (fully consented) for their data to be used for AI training and shared under controlled licensing.
This is a living dataset: new recordings are added daily, so total hours increase over time (Nigeria segment: 1,740 hours as of 26 August 2026; full catalogue 18,538 hours).
Each clip is primarily single-speaker (candidate-focused), making it highly valuable for training models on authentic, real-world monologue speech in interview conditions.
Unlike staged or scripted recordings, this dataset captures authentic interview behavior — spontaneous phrasing, pauses, disfluencies, turn-taking, and real-world device variability. The video modality adds valuable capture signals that improve model generalization to production environments.
Key Features
1) Accent Diversity at Scale (Underrepresented Accents Included)
Designed for real-world robustness with broad English accent coverage:
- Diverse regional accents and speech patterns
- Variation in pronunciation, rhythm, speech speed, and vocabulary
- Nigerian English across regional accent groups, recorded on the speaker’s own device
2) Real Interview Video (Non-Scripted, Natural Speech)
All sessions come from genuine interview-style Q&A, capturing:
- Natural disfluencies (hesitations, self-corrections, fillers)
- Realistic interview pacing and tone
- Authentic response structure under real interview conditions
3) AI-Ready Packaging (Video + Transcript + Context)
Each session can include synchronized assets such as:
- Video with embedded audio (online interview capture)
- Timestamp-aligned transcripts (segment/sentence level)
- Question prompts, verbatim, on 85% of answers; question type/category where the employer configured one (20%)
- Technical and quality metadata (duration, device/channel signals)
Supports tasks including:
- Audiovisual speech recognition
- Lip/audio alignment research
- Speech modeling
- Multimodal conversational understanding
4) Real-World Capture Conditions
Video reflects realistic online interview environments:
- Mobile and desktop capture
- Consumer-grade device cameras and microphones
- Mostly indoor environments with natural lighting/background variation
- VoIP-style audio characteristics and device differences
5) Fully-Consented & Commercial-Ready
- Explicit opt-in consent for AI training and controlled dataset sharing
- Packaged for smooth integration into ML pipelines and enterprise procurement workflows
6) Continuously Expanding Library (Daily Updates)
- New recordings added every day
- Monthly intake: 3,000–4,200 new hours (June 2026: 4,165 h; July 2026: 4,220 h)
- Custom collection to brief: language, region, job family or question set — capacity on request
- Current total: 1,740 hours in Nigeria; 18,538 hours across the full catalogue (26 August 2026)
- Updated releases available upon request
