Title: Le Avventure di Pinocchio (English: The Adventures of Pinocchio)
Author: Carlo Collodi (1826 - 1890)
First Published: 1883
The text is in the public domain worldwide, as the author died in 1890 and more than 70 years have elapsed since his death.
The audio was sourced from LibriVox, a volunteer-driven project founded in 2005 with the goal of recording all books in the public domain and making them freely available as audiobooks. All recordings are released into the public domain under the LibriVox license, meaning they may be freely used, distributed, and adapted for any purpose, including the creation of speech datasets. The recording used for this dataset features a single female reader.
The dataset was constructed by sentence-aligning the source text with the LibriVox audio recording of Le Avventure di Pinocchio. In this context, "sentence" is a best approximation using sentence-final punctuation. In order to obtain sentence-level alignments, the Montreal Forced Aligner was used to produce word-level alignments, which were then rolled up to the sentence level.
The original audio contains a LibriVox introduction that is not represented in the source text. This was removed for each chapter.
The original mp3 files used a variable bitrate. To ensure compatibility and simplify data validation, they were converted to a constant bitrate (128 kb/s).
The alignments were manually inspected and small typos in the source text were fixed.
