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:regime_persistence (+3.8z) — beyond what the standard bank predicts for it. It sits beside Earthquake P-wave in the atlas (standard-bank rank 58) — a neighbor conventional features miss.
Nonstationarity:regime_persistence | +3.8z | bank-miss 1.1σ |
Nonstationarity:metric_volatility | -2.0z | bank-miss 1.6σ |
