This dataset is a modified version of Common Voice Scripted Speech 23.0 - Spanish. We added a new phonemes_ipa column, which contains phonemized sentences in the IPA format. We use babygruut to phonemize the sentences. This large-scale dataset provides a broad foundation of Spanish speech. It contains 1,672,761 utterances, representing 449 hours of validated speech from over 26,800 speakers.
