# tts-test-sentence
One canonical **TTS test sentence** — the *rainbow sentence* — translated across
languages and scripts, for quickly sanity-checking multilingual text-to-speech
voices (does the voice produce intelligible speech in its language?).
**English source:** *After the rain, a colorful rainbow appeared in the sky, and the children went outside to look at it.*
Each row: `lang` (BCP-47), `language` (name), `script` (ISO-15924), `text`
(native translation), `source_en`. Some languages appear in multiple scripts
(e.g. Serbian: `sr-Cyrl` / `sr-Latn`).
```python
from datasets import load_dataset
ds = load_dataset("OpenVoiceOS/tts-test-sentence", split="train")
```
Many translations are best-effort (some AI-authored); corrections and additional languages/scripts are very welcome. The ~1000 long-tail MMS languages (one voice each) are not yet covered.
