Commission speech datasets for voice AI

Spirelight builds speech datasets to order rather than reselling a fixed inventory. Each catalogue page is a custom collection configuration for one language: recruitment, recording, transcripts, QA, consent records, and commercial training rights are confirmed in writing against your brief. If you need a speech recognition dataset, an ASR evaluation set, or conversational audio in a specific language, request a quote on the matching page and get a free sample.

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.

Spirelight sells commissioned collection, not an off-the-shelf download library. Where a relevant sample from consented prior work is available, the team can share it after a verified request so you can inspect audio, transcript, and metadata quality before commissioning. The catalogue pages state availability honestly instead of presenting planned collection as finished stock.
