Singer Voice Tester

The SingerVoiceTester (SVT) program is designed to test the user's singing abilities by analyzing a sufficiently long interval (about 10 seconds) of the acoustic signal of his singing. To do this, a histogram of the frequency distribution of the pitch frequency (F0) of the singer's voice on a 4-octave musical scale is calculated. Based on the obtained histogram, two modes of program operation are implemented:
- determination of the type of singing voice (bass, baritone, tenor, contralto, mezzo-soprano, soprano);
- testing and evaluating the practical possession of the singing voice in the game mode by evaluating its differences from the reference performance in terms of voice pitch and range.
