# Twi Speech Segments (sentence splitting)
52562 speech-text pairs split from long recordings.
## Processing pipeline
1. Source audio from `ghananlpcommunity/navigation-corpus-speech-full-twi`
2. Full-file CTC forced alignment (MMS-300M) for word-level timestamps
3. Sentence-boundary splits (. ? !) — long sentences re-chunked to 16 words
4. Leading/trailing silence trimmed with VAD (-40 dBFS threshold)
5. Filtered: min 1.0s, max 15.0s
6. Original sample rate preserved
## Usage
```python
from datasets import load_dataset
ds = load_dataset("ghananlpcommunity/navigation-corpus-twi-speech", split="train")
```
