VoiceLab

Workflow and reliability tooling for voice.

Not another voice generator. VoiceLab focuses on the boring-but-essential layer: QA, cleanup, pacing, pronunciation, and dubbing-prep pipelines.

VoiceLab QA

Analyse a voice sample for clarity, pacing, filler density, room echo, clipping risk, and consistency across takes.

Mic capture and analysis stay in your browser. Nothing is uploaded.

How this is measured
02 Use cases
01

Podcast QA before publish

Catch room echo, pacing dips, and inconsistent loudness before the episode goes live.

02

Localization safety net

Flag pronunciation risks and pacing mismatches across language variants before dubbing finalises.

03

E-learning narration consistency

Keep tone, pace, and clarity coherent across 200 recorded modules from three voice actors.

03 What makes it different

We don’t generate voices. We make the voices you already have (yours, your hosts’, your hired talent’s) measurably better and more consistent.

Also in VoiceLab

  • Pronunciation checker

    Flag risky words against your target locale.

  • Cleanup preview

    See what cleanup will do before you commit.

Free in the browser · API + MCP at scale

Run VoiceLab from your own code or any AI agent.

The demo above runs free, on your device. The same analysis is a hosted REST API and an MCP server — one key, EBU R128 / BS.1770-4 verified. VoiceLab exposes 2 endpoints / 2 MCP tools.

REST · POST

  • /v1/voicelab/qa speech-quality QA
  • /v1/voicelab/segments speech segments

MCP tools · https://audiolab.tools/mcp

  • analyze_voice
  • get_speech_segments

Where this leads.

MixLab

Master and check loudness

Push the voice take to MixLab Analyzer for BS.1770-4 LUFS, true-peak, and tonal-balance verification.
HearLab

Test for hearing-aid users

Run the same voice file through HearLab to see how it would land for an assisted-listening audience.
SignalLab

Find every voice segment

For long-form material, let SignalLab auto-detect speech regions and timestamp them for editing.
CueLab

Route into a broadcast chain

Use CueLab to plan mic-routing, mix-minus, and recording paths for your show before going live.
SkillLab

Drill sibilance and noise

SkillLab includes critical-listening drills that train the same dimensions VoiceLab QA scores.

MixLab, VoiceLab, and SignalLab hand audio off to one another without re-uploading. When you finish an analysis in one of those, the → Lab buttons in the demo chrome carry your decoded audio directly into the next lab’s analysis flow. The other labs open fresh.
