Description

“RSC” is a read speech corpus collected by Speech and Dialogue Research Laboratory. The recordings were made under different conditions (various microphones and various audio recording systems), using an online audio recording application developed by the same research group. The speakers were mainly students and staff of Faculty of Electronics, Telecommunications and Information Technology from University “Politehnica” of Bucharest.

The corpus consists of 136,120 audio files collected from 164 Romanian native speakers. Each audio file contains utterances from literature, online news and isolated words in Romanian language. In general, there are between 130 and 11,000 audio files per speaker. The total size of the database is around 100 hours. The average length of an utterance is 2.6 seconds.

“RSC” is split into training, and evaluation sets, as follows:

  • training set: 133,616 files from 156 speakers
  • evaluation set: 2,504 files from 21 speakers (out of which 13 speakers are also part of the training set)

Note: the above overlap occurs only in terms of speakers (voices), not in terms of utterances.
