Introduction

Avatar Education Portuguese was developed by the University of Pernambuco and consists of approximately 80 minutes of Brazilian Portuguese microphone speech with phonetic and orthographic transcriptions. The data was developed for Avatar Education, an animated virtual assistant designed to enhance communication and interaction in educational contexts, such as online learning.

Data

The corpus contains 1,400 utterances (700 male and 700 female) of read and spontaneous speech spoken by two professional speakers. Utterances were transcribed at the word level (without time alignments) and at the phoneme level (with time alignment labels).

The audio data was recorded at 16kHz (mono, 16-bit) using Pro Tools recording software and stored in flac compressed wav format. The acoustic environment was controlled for background conditions that occur in application environments.
