Voice AI Workflows

Automated Quality Governance for AI Training Data

A voice data operation replaced manual QC review with a 7-stage automated evaluation pipeline — routing 11 submissions per evaluator-hour, with full audit provenance for every decision.

Multi-language pipeline, 60–70% auto-routed, 100% audit provenance.

The Situation

A voice data operation collecting Indic language recordings for AI training had no automated quality layer between contributor submission and dataset delivery. Every submission went to a human reviewer who had to assess audio quality, transcription accuracy, language authenticity, and prompt adherence manually — with no scoring system, no routing logic, and no audit record. Review throughput was capped at what human attention could sustain. Regulatory and lab compliance requirements increasingly demanded a traceable decision chain: which model evaluated which sample, what scores each dimension received, and what routing decision was made and why.

Every submission went to a human reviewer — regardless of whether it needed one.

What Was Breaking

Why manual operations couldn't scale

01

No triage before review.

Every submission — obvious pass or genuine edge case alike — went to the same human review queue, with no scoring system to separate them.

02

Throughput was capped at human attention.

Review speed could only ever match reviewer capacity, with no way to absorb a submission spike.

03

There was no decision record.

Nothing captured why a submission was accepted or rejected — a growing liability as DPDP and EU AI Act provenance requirements started asking not just 'was this reviewed' but 'what specifically was evaluated, by what standard, and by whom.'

The approach

The Approach

1

Connect your pipeline sources

Submission DB, audio storage, and LLM API connected read-only — 2 weeks to POC.

2

Configure quality thresholds

Scoring dimensions, routing rules, and compliance requirements set in plain language — no ML engineering.

3

Autonmis routes every submission

7-stage evaluation runs automatically. Every decision is logged with full model and score provenance.

Auto-Accept Queue
Human Review Interface
Immutable Audit Trail

Built a 7-stage evaluation pipeline on top of the Autonmis governed infrastructure: audio quality gate, ASR transcription, language and code-switch detection, acoustic scoring across 7 dimensions, LLM semantic evaluation (authenticity, naturalness, prompt adherence), weighted score aggregation, and confidence-based routing to auto-accept, human review, expert review, or auto-reject. Every stage wrote structured outputs to the database. The human review interface showed the transcript with language segments highlighted, a 10-dimension radar chart, and a one-click accept/reject/flag decision — with every action logged to an immutable audit trail including model versions, score reasoning, and timestamps.

The governance layer tracked every state transition from submission through final dataset inclusion. A non-technical ops lead could query routing distributions, score trends, and per-contributor quality without writing a single line of SQL.

Human in the LoopHuman review is reserved for submissions the pipeline routes below the 0.85 auto-accept threshold; expert review triggers on the lowest-confidence band; nothing is auto-rejected without a logged model rationale.

Governance Note

Every routing decision resolves to a score computed against the same 7-dimension rubric the ops and compliance team defined up front — not a black-box model call with no record of what it evaluated.
