The 'l' in člověk is voiced as well.
When in doubt, you can use forvo.com, although do post on the forums for the benefit of everyone. Forvo contains pronunciations spoken by native speakers.
P.S.: I see you are a PLUS user. How would you describe your experience? What's significantly different from the free version? I am thinking of making the switch.
"Mladý" is for the masculine gram. gender: "mladý muž" (young man). "Mladá" is used for the feminine gram. gender: "mladá dívka" (young girl). Remember that while the gram. gender usually coincides with the real gender when talking about people, it's not always: "děvče" has the neuter gram. gender, and the result is "mladé děvče".
