Urban nighttime audio narrations layered over real traffic and ambient noise, with noise profiling for robust speech models.
Spoken English narrations recorded in real urban nighttime environments, captured against authentic traffic and ambient noise rather than added in post. Each clip ships with a noise profile so models can train and evaluate against measured, real-world acoustic conditions.
Every recording is collected from paid contributors with signed consent, transcribed by native reviewers, and screened for personal information before delivery.
Highlights
- Authentic urban nighttime traffic and ambient noise, captured live
- Per-clip noise profiling, including signal-to-noise estimates
- Spoken narration with timestamped native-speaker transcripts
- Varied environments: streets, intersections, transit, and open squares
- Consent-cleared and PII-reviewed before delivery
Environment coverage
A range of urban nighttime settings and noise conditions. Coverage extends to specific environments, cities, or noise targets on request.
Capture and format
WAV at 44.1 kHz or higher captured on calibrated field recorders, with ambient noise recorded in situ. Each clip includes a noise profile and signal-to-noise estimate.
Annotations
Timestamped native-speaker transcripts and per-clip noise profiles as standard, plus optional environment and event labels on request.
Provenance
- Paid contributors with signed consent
