Build a Speaker-Diarization Pipeline for a Legal-Tech Startup

FreeVerified credential2 weeksAdvanced

Overview

What this challenge is about.

Build a speaker-diarization pipeline for legal-tech audio, tune it for 2-6 speakers, and hit under 12% DER to earn your verifiable certificate.

The scenario

The startup (around 20 staff, seed-funded, 6 UK chambers as customers) needs to cut paralegal labeling time in half to expand to a second customer segment.

The Brief

What you'll do, and what you'll demonstrate.

Build a speaker-diarization pipeline that brings DER under 12 percent on legal-hearing audio.

Earning criteria — what you'll demonstrate

  • Build a modern speaker-diarization pipeline
  • Evaluate diarization with DER and sliced analysis
  • Tune diarization for a known-cardinality speaker setup
  • Document integration with an existing ASR stack

Program Fit

Where this fits in your program.

Sharpens the same skills your degree expects you to demonstrate.

Master · Nlp

Strong alignment

This challenge maps to Speech Recognition and Spoken Language Processing at the Master level. It sharpens the same practical skills your coursework expects — but in a real industry context with actual constraints and deliverables.

Careers

Career paths this challenge builds toward

Completing this challenge demonstrates skills that transfer directly to these roles:

NLP Engineer

Owning the diarization layer on top of ASR is the day-to-day work of NLP/speech engineers at any voice-transcription startup.

This challenge sharpens

  • speaker-diarization
  • speech-recognition
  • pyannote

Machine Learning Engineer

Integrating two ML components (ASR + diarization) into a shippable pipeline is core MLE craft.

This challenge sharpens

  • pyannote
  • evaluation
  • pytorch

Applied AI Scientist

Sliced evaluation on the hard cases (witness-vs-defense) and a written integration memo are bread-and-butter applied-AI work.

This challenge sharpens

  • speaker-diarization
  • audio-processing
  • evaluation
