Project Steps
01
Discovery & requirements scoping
- We analyze your data, define the methodology, and assign a dedicated project lead. The right annotation type and domain-matched annotators are confirmed before anything starts.
02
Audio strategy & source planning
- We design a collection plan combining field, studio, crowdsourced, and synthetic methods to achieve the acoustic diversity your model needs, with a sampling strategy that balances environments, devices, and demographic variation.
03
Pilot batch & quality check
- A test batch is collected, processed, and reviewed against your quality criteria — SNR thresholds, annotation accuracy, format conformity — before full-scale production begins.
04
Full-scale collection & annotation
- Collection runs across all planned channels simultaneously. Annotation teams apply event labels, timestamps, speaker tags, and custom taxonomy markers with real-time QA oversight.
05
Quality assurance
- Automated signal quality checks (SNR, clipping, silence ratio) run alongside human review and inter-annotator agreement scoring. Only files meeting agreed thresholds pass to delivery.
06
Delivery & ongoing support
- Datasets are delivered in your specified format and codec via secure transfer or cloud bucket. We support iterative dataset expansion, domain-specific fine-tuning batches, and long-term collection partnerships.
Frequently Asked Questions
Is the data collection process compliant with data privacy laws?
Yes. Each dataset follows GDPR guidelines and complies with applicable data protection laws. Data is collected from legal sources to ensure responsible usage.
