PROJECT FOCUS / SPC-001

Speech & content · Case study

From recorded dialogue to traceable intent labels

Segment recorded dialogue into speaker-attributed, time-aligned turns, then link transcripts, intents and entities so every label retains its context.

DATA IN CONTEXT
Audio waveforms, headphones and a transcription review desk
60Recordings
300Audio minutes
6Intent classes
Project scope and counting rules are defined below.

THE BRIEF

Define what the data needs to support.

Organize audio and text for service-dialogue understanding. Review transcripts, time boundaries and intent labels separately so context is not lost in text-only checks.

SCENE COVERAGE

Break the scope into reviewable groups.

01

Clear single-speaker recordings

20

Agree how to transcribe numbers, proper nouns and colloquial expressions.

02

Two-speaker dialogue turns

20

Record speaker changes, contextual references and overlapping speech.

03

Recordings with background noise

20

Mark unintelligible portions and non-speech events.

FROM CHALLENGE TO METHOD

Connect each decision to a record.

DECISION / 01

Mixed transcription conventions

01 / THE APPROACH

Agree verbatim transcription rules for numbers, pauses and fillers.

02 / THE REVIEW TRAILTranscription guidelines and terminology list
DECISION / 02

Ambiguous turns and speakers

01 / THE APPROACH

Review speaker changes against audio, retain overlap markers and keep unintelligible speech distinct from confirmed text.

02 / THE REVIEW TRAILTime-boundary and speaker records
DECISION / 03

Ambiguous intent within an utterance

01 / THE APPROACH

Use surrounding turns and record multiple intents or uncertainty rather than forcing context-free classifications.

02 / THE REVIEW TRAILTurn links and label rationale
Every step leaves a record.

REVIEW & HANDOVER

Review the task. Verify the delivery.

Review focus

Audio–text consistency

Listen again for transcript differences, omissions and unintelligibility markers.

Temporal associations

Check segment boundaries, speaker identities and overlap spans.

Labels & privacy

Review intent rationale, entity spans and agreed de-identification rules.

Delivery contents

  1. 01

    Audio & segment index

    Link original recordings, segment timestamps and speaker IDs.

  2. 02

    Transcripts & semantic labels

    Deliver turn transcripts, intents, entities and contextual relationships.

  3. 03

    Vocabulary & review records

    Retain terminology, rule versions, difficult segments and review notes.

WHAT TO TAKE FORWARD

What matters for the next project

Correct transcription does not guarantee correct semantic labels. Keep audio, text and context connected so each layer can be reviewed independently.
