Sourcing field guide
Mono and stereo call recordings: what to inspect
Channel count alone does not tell you whether callers and agents are separated.
Sourcing field guide
Specifying speaker diarization labels for calls
Define speaker turns, overlap, and role mapping separately from the words being spoken.
Sourcing field guide
Transcription conventions for conversational call audio
Make hesitation, numbers, uncertainty, and interrupted speech consistent across a call corpus.
Sourcing field guide
Measuring language coverage in call datasets
Count languages, conversation types, and independent speakers rather than relying on a broad multilingual label.
Sourcing field guide
Code-switching in telephone speech datasets
Define mixed-language segments and annotation rules without forcing a whole conversation into one language.
Sourcing field guide
Domain vocabulary in call datasets
Specify the terms and conversational contexts your telephone speech model needs to handle.
Sourcing field guide
Assessing recording quality in telephone audio
Inspect intelligibility, clipping, gaps, and channel behavior before deciding which calls fit a model task.
Sourcing field guide
Call duration versus usable speech: counting audio honestly
Clarify whether dataset volume means elapsed recordings, speech activity, or reviewed task-ready material.
Sourcing field guide
Transfers and multiple speakers in call datasets
Preserve agent handoffs, supervisors, interpreters, and changing participant structure.
Sourcing field guide
Overlap and interruptions in conversational call audio
Build a useful evaluation slice for simultaneous speech and rapid turn exchanges.
Sourcing field guide
Creating an intent taxonomy for call datasets
Define call reasons and segment labels that support a concrete classification task.
Sourcing field guide
Reference data for call summarization
Connect concise summaries to audible evidence without inventing facts or exposing unnecessary details.
Sourcing field guide
Defining evidence-based call quality labels
Create observable conversation labels without presenting subjective judgments as objective truth.
Sourcing field guide
Planning a privacy review workflow for call audio
Describe spoken information, derivatives, exceptions, and review evidence before using call recordings.
Sourcing field guide
Call audio provenance: source questions that matter
Understand capture, selection, transformation, and project scope before evaluating a call collection.
Sourcing field guide
Authentic and roleplay calls: choosing a dataset mix
Distinguish operational conversation patterns from controlled scenarios when planning training or evaluation.
Sourcing field guide
Speaker grouping in call dataset evaluation
Decide what should stay together when agents, callers, and repeated conversations appear across recordings.
Sourcing field guide
Keeping call audio, transcripts, and timestamps aligned
Preserve timing references when recordings are trimmed, split, transformed, or annotated.
Sourcing field guide
Building telephone noise and channel robustness slices
Evaluate difficult audio conditions without losing track of their origin or task relevance.
Sourcing field guide
Hold music, menus, and silence in call corpora
Decide which non-conversational regions to retain, annotate, or exclude for a telephone task.
Sourcing field guide
A delivery specification for call audio datasets
Describe audio files, transcripts, labels, manifests, and exceptions as one connected package.
Sourcing field guide
How to review a call dataset pilot
Use a small representative sample to test task fit, audio integrity, annotations, and source documentation.
Sourcing field guide
Writing a useful call dataset sourcing brief
Give a sourcing partner enough detail to discuss telephone audio that supports your actual model task.
Sourcing field guide
Speaker roles and metadata in call datasets
Distinguish caller, agent, interpreter, and supervisor roles from identities and inferred attributes.
Sourcing field guide
A buyer’s checklist for call-center audio datasets
Specify authenticity, languages, channels, transcripts, and privacy requirements.
Sourcing field guide
Speaker diarization versus separate call channels
Understand speaker labels, isolated tracks, and the different review questions they raise.
