This dataset is a single-speaker speech corpus in Ladino, recorded by Karen Şarhon, a native speaker from Istanbul. Ladino (also called Judeo-Spanish or Judezmo, ISO 639-3: lad) is a descendant of the old Castilian Spanish of the 15th century — essentially the medieval Spanish spoken at the time of the 1492 expulsion of the Sephardic Jews, which evolved separately over 530 years in the Ottoman Empire and is today classified as severely endangered by UNESCO. The corpus was built by having the native speaker read 30 articles from the weekly newspaper El Amaneser (the only newspaper published entirely in Judeo-Spanish), covering historical issues, current affairs, cultural events and politics. The recordings were automatically aligned and manually verified, then segmented into 1,987 clips (16 kHz, 16-bit, mono WAV) totalling approximately 2 hours 15 minutes of speech, each paired with its transcription. The corpus was created for training text-to-speech synthesis models and was structured and curated by Col·lectivaT as part of the project "Judeo-Spanish: Connecting the two ends of the Mediterranean", funded by the European Union via the CCH-II Grant Scheme.

This dataset is a single-speaker Ladino speech corpus recorded by Karen Şarhon, a native speaker from Istanbul. Ladino (Judeo-Spanish / Judezmo, ISO 639-3: lad) is a descendant of the old Castilian Spanish of the 15th century that evolved separately for over five centuries after the 1492 expulsion of the Sephardic Jews. The native speaker read 30 articles from the weekly newspaper El Amaneser; the recordings were automatically aligned (using a Coqui Speech-to-Text Spanish model) and manually verified, then segmented into 1,987 clips totalling approximately 2 hours 15 minutes of speech, each paired with its transcription. The package includes WAV audio files (16 kHz, 16-bit, mono) under clips/train/ and a metadata.tsv covering all 1,987 entries with columns: path, split, audio_id, text, and duration.
The dataset was structured and curated by Col·lectivaT as part of the project "Judeo-Spanish: Connecting the two ends of the Mediterranean", carried out together with the Sephardic Center of Istanbul.
A Glow-TTS speech synthesis model trained on this dataset is available at collectivat/ladino-tts.
