Multilingual natural speech
CommissionableSpontaneous, natural speech from native speakers outside studio conditions — real acoustic environments with engine noise, traffic and overlapping speakers — across languages underrepresented in commercial speech corpora.

Why this data is novel
Most available speech data is scripted, narrow in language coverage, or studio-recorded. Scripted corpora do not close the low-resource gap; this program class produces natural speech in deployment-like conditions under a defined capture specification.
Source methodology and collection context
Native speakers within established networks opt into defined capture tasks. Acoustic conditions, prompts or task structure, and session parameters follow the capture specification.
Composition (organic-data statement)
Human speech only; no synthetic voices. AI-assisted transcription, where used, is disclosed and quality-checked against human review samples.
Public availability and prior licensing
Pending verification — Commissioned output is new capture; prior-licensing status stated per program
Duplication, overlap and contamination
Pending verification — Overlap with public speech corpora assessed and reported per program
Rights and permitted uses
Consent at task acceptance for the declared purpose. All-party consent requirements are resolved in the jurisdiction review before any recording.
Privacy, PII and de-identification
Voice is personal data: jurisdiction-specific review covers biometric and voice-data handling, retention and de-identification options before activation.
Quality, acceptance criteria and known limitations
Two-stage verification: automated audio integrity checks plus independent adjudication against written acceptance criteria, with transcription quality sampling where applicable.
Delivery
Secure transfer with versioned manifests, checksums, consent attestation and rejection analysis.
Commercial structure
Commissioned program (buyer-specific). Exclusivity where required, priced as a rights grade.
Evaluation pack
Buyer diligence is productized. A qualified request receives an evaluation pack containing:
- Representative stratified sample
- Dataset card
- Data dictionary and schema
- Provenance summary
- Rights and consent summary
- Privacy and PII assessment
- Quality and novelty report
- Known limitations
- Security and delivery sheet
- Version and checksum manifest
Samples are never cherry-picked: each pack states whether its sample is representative, illustrative, anonymized, or structurally simulated.
