This dataset contains approximately 1.5 hours of scripted speech for Brazilian Portuguese (pt-BR) from a single speaker.
Brazilian Portuguese is the set of varieties of the Portuguese language native to Brazil.
There are no variants defined for this dataset.
The age and gender of the speaker was not reported. Dataset names may be gendered, but were assigned according to the speaker's preference only.
The text corpus comes from Piper Recording Studio, which extends Microsoft's samples TTS scripts for Azure.

To use these example scripts for training, it's recommended that you should do the sanity check to make sure it matches what the voice talent actually speaks in the audio and normalize the text before uploading the data. For example, change '50%' to fifty percent and '$45' to forty-five dollars. Normalization should apply to the scripts that contain digits, symbols, abbreviations, date, and time.
Statistics for the text corpus:
