Multilingual LibriSpeech Spanish Phoneme

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).
