# Multilingual LibriSpeech Spanish Phoneme

## Dataset Description

- **Repository:** [Cnam-LMSSC/multilingual_librispeech_spanish_phoneme](https://huggingface.co/datasets/Cnam-LMSSC/multilingual_librispeech_spanish_phoneme)
- **Point of Contact:** [Cnam-LMSSC Team](https://huggingface.co/Cnam-LMSSC)

### Dataset Summary

This dataset is a **curated version of the Spanish subset of Multilingual LibriSpeech (MLS)**, enriched with a phonetic transcription column (`phoneme`).

The **Laboratoire de Mécanique des Structures et des Systèmes Couplés (Cnam-LMSSC)** created this version to facilitate research into Spanish acoustic modeling, phoneme recognition, and speech synthesis. It builds upon the high-quality audio derived from LibriVox audiobooks found in the original MLS dataset.

### Supported Tasks
- **Phoneme Recognition:** Training models to map audio features directly to IPA phonemes.
- **Automatic Speech Recognition (ASR):** Robust speech-to-text tasks using audiobook data.
- **Text-to-Speech (TTS):** Utilizing the high-quality, read-speech nature of LibriSpeech for synthesis.

### Languages
The dataset contains audio in **Spanish (`es`)**.
