People who are the subject of Wikipedia article are invited to record short samples of their spoken voice, to illustrate the articles about them, so that we know what they sound like; and how they pronounce their names:

Multilingual subjects can contribute in each language they speak.
Existing contributions and a suggested script can be heard at:
