Speech training data built to your model requirements

We collect, record, transcribe, and quality-check custom speech datasets for AI training. Every project is matched to your required languages, speaker profiles, dialects, recording format, metadata, and background noise conditions, so your team receives clean, structured files ready for model development.

Workflow

Four phases, one partner, one timeline.

We manage the entire pipeline from your initial data spec to audited, deployment-ready voice files.

01 · Speech collection

Finding speakers and capturing audio to your exact specifications.

Remote · On-site DA · SV · NO · DE · FI Monologue · Dialogue Custom metadata
Contributors recruited by language, dialect, age, gender, and location.
Remote captures via our platform; on-site captures with calibrated rigs.
Prompts, device rules, and noise checks configured per project.
02 · Transcription

Machine-assisted or human-validated transcripts with annotation rules to your spec.

Manual · ASR-assisted Word timestamps Speaker IDs JSON · VTT · TXT
[00:01.420 → 00:01.890] spk_02 · word-level alignment ✓
Multi-pass review for high-stakes domains, single-pass for fast turnaround.
Overlap, accent, and domain terminology handled by humans.
03 · Dataset delivery

Audio, transcripts, metadata, and manifests packaged for your training pipeline.

Bucket · API handoff Naming conventions Manifest + checksums Consent linkage
/dataset/da-DK/spk_044/take_03.wav · sha256 · meta.json
Schema agreed up front; delivery matches your training format exactly.
Every utterance traceable to consent, contributor, and capture conditions.
04 · Quality auditing & oversight

Strict quality gates that guarantee clean, deployment-ready data.

In-production review Statistical sampling Batch gates Issue escalation
Reviewers inspect recordings while the project is live, not after.
Each batch passes a quality gate before it enters the final delivery.
Audio, transcript, metadata, and format checked against project specs.

Speech collection

We source targeted profiles and capture raw audio to your exact dataset specifications. Your pipeline gets authenticated voice files recorded under precise acoustic conditions.

Audio variations:

  • Multi-device and platform remote captures
  • Calibrated on-site acoustic hardware field rigs
  • Monologue, dialogue, and natural conversations

Transcription and annotation

We convert voice audio into time-aligned, multi-pass text scripts built for model consumption. Every file is stamped and validated according to your custom validation criteria.

Data treatments:

  • High-speed machine transcripts with human review
  • Deep domain-specific terminology labeling
  • Word-level alignment and speaker separation tags

Dataset delivery

We deliver the complete asset matching your exact pipeline format. Your engineering team gets structured files ready for model training.

Available handoffs:

  • Secure cloud bucket transfers
  • Direct API integrations
  • Scheduled batch deliveries

Quality auditing and project oversight

We run validation checks directly inside active production so formatting errors or speaker variances are fixed instantly. Your team avoids downstream engineering delays caused by messy data.

Validation actions:

  • Real-time audio and metadata inspections
  • Strict quality gates before final batch handoffs
  • Cross-batch consistency and error resolution
Quality auditing in detail

Six controls running on every project.

Quality auditing runs inside production, not at the end. These are the checks that run on every batch, every contributor, and every delivery.

In-production review

Reviewers inspect recordings and transcripts while the project is live, so issues are caught during production.

Measurable checks

Audio quality, transcript accuracy, metadata completeness, and format compliance are checked against the project spec.

Batch handling

Large projects run in batches. Each batch passes its own quality gate before it enters the final delivery.

Issue escalation

Detected issues are escalated and resolved during production rather than discovered after delivery.

Consistency controls

Cross-contributor and cross-batch consistency checks keep the full dataset to the same standard throughout.

Reviewer sampling

Statistical sampling of recordings and transcripts validates quality without bottlenecking production throughput.

How we onboard you

Three milestones from kickoff to delivery.

What happens once you bring us your project, and what you receive at each step.

01 · Scope

Align on data specifications.

We audit your data spec to finalize speaker profiles, linguistic requirements, and target noise conditions upfront. You get a fixed scope before production begins.

02 · Build

Transparent progress via live batch delivery.

We launch recruitment and tracking on our secure pipeline. Instead of a black-box handoff at the end, data passes validation gates and ships in structured, predictable batches.

03 · Deliver

Ready to plug into your models.

We package authenticated audio files, metadata tables, and verified consent logs directly into your cloud storage. Your data arrives fully formatted and ready for model training.
