We build custom speech datasets to spec: your language, dialect, recording conditions, and volume. Tell us what you need and we will scope it and send pricing.
If the catalogue does not list the language, dialect, or recording conditions you need, Spirelight can assess a custom speech data collection brief. Recruitment, recording, annotation, QA, consent records, delivery artifacts, license terms, and exclusivity are confirmed in the written project scope.
Typical projects include conversational speech for ASR, scripted prompts for wake words and commands, and multilingual corpora for low-resource languages. Tell us your spec and we will scope hours, timeline, and pricing.
Where an evidence-verified per-hour rate is published, it is a planning reference for custom collection. The final quote defines volume, speaker profile, recording conditions, QA, delivery format, usage rights, timeline, and any exclusivity requirements.
Exclusivity and restricted-use terms can be scoped per project. Tell us the intended use, required rights, and exclusivity window so they can be documented in the quote and contract.
Yes. The catalogue describes custom collection configurations and planned formats. Any published rate, speaker target, or monthly capacity is shown only with a dated evidence record. Availability, speaker mix, schedule, rights, and delivery criteria are confirmed against your project brief before work starts.
Where a sample is available, use it to review the documented audio format, transcript structure, and annotation approach. The final project specification and acceptance criteria are agreed separately.
The catalogue lists public collection configurations. Language, dialect, location, and speaker feasibility are confirmed for each brief; contact us if your target is not listed.
Each page shows planned formats for the collection configuration. The written proposal confirms the audio container, sample rate, bit depth, channels, transcript or annotation schema, and delivery method for the project.
Use "Request quote" on a collection page and include the language, speaker profile, volume, recording conditions, intended use, and required rights. Spirelight will confirm feasibility, scope, timeline, pricing, and acceptance criteria in writing.
