# LEMAS Eval Set
Multilingual evaluation set for speech synthesis and speech understanding.
## Overview
This dataset is part of **LEMAS (Large-scale Extensible Multilingual Audio Suite)**.
It contains high-quality evaluation subsets for 10 languages with
word-level alignment.
- **Audio**: MP3, 16kHz
- **Text**: normalized transcription
- **Alignment**: word-level timestamps
## Fields
- `audio`: relative path to MP3 audio file
- `dur`: duration in seconds
- `text`: normalized transcription
- `align.txt`: normalized text used for alignment
- `align.words`: list of word-level timestamps
## Notes
- Audio is encoded in MP3 (LAME, q=3)
- All audio paths are relative to the dataset root
