Prepare the data
Use a small opt-in teaching corpus with separate recording sessions and documented deletion rights.
Compare consented recordings. Include an unknown-speaker path.
Speaker recognition compares voice characteristics under a declared identification or verification task. Voice data is biometric information and requires explicit consent and careful retention controls.

Speaker recognition compares voice characteristics under a declared identification or verification task. Voice data is biometric information and requires explicit consent and careful retention controls.
A possible application for audio research classes: Help audio students study cross-session variability using their own consented recordings. This extension is not delivered by the supplied starter.
Use a small opt-in teaching corpus with separate recording sessions and documented deletion rights.
Extract audio features and train a closed-set baseline with an explicit unknown-speaker rejection policy.
Evaluate cross-session errors and false accepts under microphone and background changes.
Keep the prototype local and educational; do not use it for access control or covert identification.
The supplied starter synthesises 160 one-second noisy tones near 440 Hz and 880 Hz. It extracts four FFT summary features, fits a 200-tree RandomForestClassifier and reports held-out binary classification results.
spectrum = np.abs(np.fft.rfft(signal))
features = [
spectrum.mean(), spectrum.std(),
spectrum.argmax(), np.percentile(spectrum, 95),
]
# Later in the supplied script, after generating and splitting tone features:
model = RandomForestClassifier(n_estimators=200, random_state=42)
model.fit(X_train, y_train)
print(classification_report(y_test, model.predict(X_test)))The source classifies synthetic tone frequencies and contains no voices or speaker labels. Distinguishing two synthetic tone ranges does not demonstrate music understanding, speaker identity, transcription or speech synthesis. The source contains no real recordings, transcripts or generated speech.
Proposed extension: Help audio students study cross-session variability using their own consented recordings.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
