FSDD spoken digit 'nine', 8 kHz waveform. Nasal onset, diphthong, sustained voicing throughout.
Standard analysis sees: no strongly notable standard properties. The atlas finds no named structure, but the source is distinctively extreme on Nonstationarity:metric_volatility (-2.0z) — beyond what the standard bank predicts for it. It sits beside Earthquake P-wave in the atlas (standard-bank rank 32) — a neighbor conventional features miss.
