Demographic information

Text corpus

The text corpus comes from Piper Recording Studio, which extends Microsoft's samples TTS scripts for Azure.

Microsoft provides the following recommendations:

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:

  • Average/median characters per sentence: 47/38

  • Average/median words per sentence: 8/7

Writing system

Bulgarian uses the standard Cyrillic alphabet.
