Prepare the data
Prepare permitted reading text and select a licensed stock voice without imitating a real person.
Turn text into audio. Use a licensed voice.
Text-to-speech converts written text into spoken audio through a synthesis model. Pronunciation, intelligibility and voice rights matter more than simply producing a waveform.

Text-to-speech converts written text into spoken audio through a synthesis model. Pronunciation, intelligibility and voice rights matter more than simply producing a waveform.
A possible application for course authors: Help course authors create draft audio versions of their own learning material. This extension is not delivered by the supplied starter.
Prepare permitted reading text and select a licensed stock voice without imitating a real person.
Use a documented synthesis model with text normalisation and controlled audio output settings.
Review intelligibility, names, abbreviations, numbers, latency and clipping with human listeners.
Offer clearly labelled synthetic audio with playback controls and no voice-cloning feature.
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 supplied code classifies synthetic tones; it accepts no text and synthesises no speech. 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 course authors create draft audio versions of their own learning material.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
