# WorldSpeech
**Highly multilingual, large-scale paired speech corpus assembled from primary public archives such as national parliaments, public broadcasters, and public-domain audiobooks across 107 language-country configs, with strong non-European and low-resource coverage.**
Every segment ships with a verified *human* transcript (not ASR pseudo-labels), an ASR transcript, the CER between them, a WADA-SNR estimate, and four DNSMOS-P.835 quality scores, so you can filter, rank, or stratify training data without rerunning a single signal-quality model.
Audio is OGG Opus 24 kHz mono ~64 kbps VBR. Splits are 95/5, full provenance (`source`, `source_url`, `session_date`, `source_start_s`/`source_end_s`, `segment_id`) is preserved on every row, so you can trace any clip back to its original parliamentary record or broadcast.
## Loading
```python
from datasets import load_dataset, Audio
ds = load_dataset("AAdonis/WorldSpeech", "nl_nl", split="train")
ds = ds.cast_column("audio", Audio(sampling_rate=24000)) # decodes Opus -> {"array": np.ndarray, "sampling_rate": 24000}
row = ds[0]
wav = row["audio"]["array"] # 1-D float numpy array, 24 kHz mono
sr = row["audio"]["sampling_rate"] # 24000
text = row["human_transcript"]
snr = row["snr"]
dnsmos = row["dnsmos_ovr"]
print(len(wav)/sr, "sec", text[:60], snr, dnsmos)
# Streaming (no full download):
ds = load_dataset("AAdonis/WorldSpeech", "nl_nl", split="train", streaming=True)
ds = ds.cast_column("audio", Audio(sampling_rate=24000))
for row in ds:
 wav = row["audio"]["array"]
 break
```
