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
