Define labels and inputs
Decide what 'low quality' means for your organisation, and select features (agent ID, call duration, transcript-derived sentiment) that map to that label.
Assess call quality. Prioritise calls for review.
Call quality evaluation seeks to flag interactions that need supervisor attention using call metadata, transcripts or derived features. Common issues include label ambiguity, class imbalance (few low-quality calls), and covariate shifts when call scripts or products change.

Call quality evaluation seeks to flag interactions that need supervisor attention using call metadata, transcripts or derived features. Common issues include label ambiguity, class imbalance (few low-quality calls), and covariate shifts when call scripts or products change.
A proposed application: flag a subset of calls each day for human quality-assurance review so supervisors focus on likely problems. The supplied starter does not implement audio or transcript processing and is not sufficient for automated personnel decisions; keep a human reviewer in the loop.
Decide what 'low quality' means for your organisation, and select features (agent ID, call duration, transcript-derived sentiment) that map to that label.
Collect real call records, extract consistent features, and address class imbalance with sampling or appropriate metrics.
Fit a simple pipeline (scaling + tree or linear model) and record seed, split and metrics for repeatability.
Surface model predictions in a dashboard and require supervisor confirmation before taking personnel action.
The supplied starter creates a synthetic classification dataset with sklearn.make_classification, builds a Pipeline with StandardScaler and RandomForestClassifier, fits the model, and prints a classification report on a held-out test split.
X, y = make_classification(
n_samples=800,
n_features=10,
n_informative=6,
n_redundant=2,
random_state=RANDOM_STATE,The code uses synthetic features from make_classification rather than call metadata, audio features or transcripts; it therefore does not validate the real task of call-quality evaluation. There is no feature extraction from audio/text, no real labels, and no production-ready data handling.
Proposed extension: replace synthetic data with CRM and transcript-derived features, then train a model that scores and ranks calls for human review so supervisors inspect the highest-risk items first.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
