# Korean Macro-Prosody Telemetry

**Language:** Korean (ko)
**Language Family:** Language Isolate
**Source Corpus:** Mozilla Common Voice CV24
**Speech Type:** Scripted
**License:** CC0-1.0 (Public Domain)

## Description

Macro-prosodic acoustic telemetry extracted from Korean speech in the Mozilla Common Voice CV24 corpus. Contains pitch, intensity, rhythm, spectral, and voice quality metrics per clip. Demographically balanced cream selection (~25 min target). No audio included. CC0 licensed.

## Dataset Contents

| Field | Value |
|---|---|
| Rows | 6,998 |
| Suppressed (k=5) | 22 |
| Format | Parquet (Snappy compressed) |
| Acoustic metrics | 20+ per clip |
| Audio included | No |

## Acoustic Features

Pitch (mean, std, range), intensity (mean, max, range), harmonics-to-noise ratio,
cepstral peak prominence (CPPS), spectral tilt, zero-crossing rate, formants (F1/F2/F3),
normalized pairwise variability index (nPVI), articulation rate, speaking rate,
pause rate, jitter, shimmer, MFC delta, TEO mean/std, speech ratio, SNR, C50.

## Anonymization

- Sequential clip IDs replace original Mozilla filenames
- Transcripts removed; approximate syllable count provided
- All continuous acoustic variables truncated to 2 decimal places (float32)
- Duration bucketed to nearest 100ms
- K-anonymity k=5 applied on {gender, age\_bucket, duration\_bucket}
- Anonymization standard: `orator_forge_k5_v1`

## Provenance

Derived from the [Mozilla Common Voice](Mozilla Common Voice CV24) CC0 corpus.
Acoustic features extracted via Parselmouth/Praat at 16kHz.
Quality-gated via Brouhaha (SNR/C50/VAD scoring).
No original audio is included in this dataset.
