ES-Port: a Spontaneous Spoken Human-Human Technical Support Corpus for Dialogue Research in Spanish

In this paper the ES-Port corpus is presented. ES-Port is a spontaneous spoken human-human dialogue corpus in Spanish that consists of 1170 dialogues from calls to the technical support department of a telecommunications provider. This paper describes its compilation process, from the transcription of the raw audio to the anonymisation of the sensitive data contained in the transcriptions. Because the anonymisation process was carried out through substitution by entities of the same type, coherence and readability are kept within the anonymised dialogues. In the resulting corpus, the replacements of the anonymised entities are labelled with their corresponding categories. In addition, the corpus is annotated with acoustic-related extralinguistic events such as background noise or laughter and linguistic phenomena such as false starts, use of filler words or code switching. The ES-Port corpus is now publicly available through the META-SHARE repository, with the main objective of promoting further research into more open domain data-driven dialogue systems in Spanish.
