CSS10-Multilingual-LJSpeech
Multilingual speech dataset combining LJSpeech (English) + CSS10 (10 languages) in a consistent LJSpeech format.
Dataset Description
This dataset merges:
- LJSpeech: High-quality English speech dataset
- CSS10: A collection of single-speaker speech datasets for 10 languages
All audio files are provided in a consistent format suitable for TTS training.
Features
Each sample contains:
- audio: Waveform audio sampled at 22,050 Hz
- text: Original transcription
- normalized_text: Normalized version of the transcription
- duration: Audio duration in seconds
A train-test split has been added for each language, where 5% of the data is reserved for testing. This split enables computation of objective metrics for TTS model evaluation.
