Description
Heroes corpus contains mapped bilingual (English and Spanish) speech segments from the TV series Heroes. It contains 7000 single speaker speech segments extracted from the original and Spanish dubbed version of 21 episodes. Audio segments are accompanied with subtitle transcriptions and word-level prosodic/paralinguistic information. Each episode directory contains word-level and segment-level information of the whole episode and also parallel samples extracted under segments_eng and segments_spa subdirectories. Each sample is stored as a wave audio file, text file and a csv file containing word timing information and word-level paralinguistic and prosodic features (speaker id, mean f0, mean intensity).

Ethical Review
The Heroes corpus consists of short, isolated speech segments (averaging about 2.5 seconds each) extracted from dubbed TV episodes, annotated with prosodic and linguistic features for computational linguistics research. The segments are decontextualized and cannot be used to reconstruct the original audiovisual content — they serve a fundamentally different, transformative purpose from the original work. The corpus was created at Universitat Pompeu Fabra and published through their institutional repository under a CC BY-SA 4.0 license. The methodology and fair use justification are described in the peer-reviewed paper "Corpora compilation for prosody-informed speech processing" (Öktem, Farrús & Bonafonte, 2021, Language Resources & Evaluation, Springer). Under EU Directive 2019/790 (Article 3), text and data mining for scientific research purposes by research organizations is permitted, which applies here. The dataset would only be made available for research purposes. Given the nature of the extracted segments — short, fragmented, prosodically annotated, and representing a small fraction of the source material — there is no risk of substitution for the original copyrighted work.
Intended Use
Research on dubbing, automatic dubbing, spoken machine translation
