Speech data projects break down in predictable places: recruitment that does not match the spec, capture quality that varies too much, workflows that fragment across vendors, and delivery structures that do not fit the client's pipeline.
We built Spirelight around solving those problems. Not as a general annotation company, but as a focused partner for teams that need custom, difficult, operationally real speech datasets.
We understand that the value is not in volume alone. The true value lies in getting the right speakers, the right scenarios, the right formats, and a workflow that holds together from start to delivery.
We do not try to be everything. We focus on custom speech data, handling the projects that are too specific for off-the-shelf datasets and too operationally complex for generalist vendors.
We would rather deliver exactly what you need than overwhelm you with volume that does not match the spec. Every project is scoped to your real requirements.
Quality control runs during production, not only after delivery. Reviewers sample files while recording is live. Issues are flagged before they multiply.
Collection, transcription, QA, and packaging happen in one coordinated chain. No handoff gaps. No format translation between vendors.
We are built for the projects that other vendors find too specific. Tell us what you need and we will tell you how we would run it.
