# 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.
