  • *Introduction*

    West Point Brazilian Portuguese Speech is a database of digital recordings of spoken Brazilian Portuguese designed and collected by staff and faculty of the Department of Foreign Languages (DFL) and Center for Technology Enhanced Language Learning (CTELL) to develop acoustic models for speech recognition systems. The U.S. government uses such systems to provide speech-recognition enhanced language learning courseware to government linguists and students enrolled in various government language programs.

    The data in this corpus was collected in March 1999 in Brasilia, Brazil using informants from a Brazilian military academy. The corpus consists of read speech from 60 female and 68 male native and non-native speakers.

    The speech was elicited from a prompt script containing 296 sentences and phrases typically used in language learning situations. The prompts are listed in the file prompts.txt. Each line of this file has two fields separated by a tab: the first field denotes the base name of the waveform file; and the second field denotes the prompt used to record the utterance.

    A pronouncing dictionary developed by Dr. Sheila Ackerlind with help from cadet Sterling Packer is provided in the file SANTIAGO.txt.

    The speech was collected using four laptop computers running MS Windows. Three of the computers recorded with a 16 bit data size and sampling rate of 22050 Hz, the other laptop recorded with an 8 bit data size at a sampling rate of 11025 Hz. The recording script presented a visual display of the sentence to be recorded. The informant pressed a key and spoke the sentence. The recording was played back for review, allowing the utterance to be re-recorded. A member of the data collection team was present during the recording session to verify recordings and to provide technical assistance in case of malfunctioning equipment.
