His voice is common enough to those working in and around the White House, but Kushner on Monday gave rare public remarks.
In mid-to-high pitch, with long vowels and smooth consonants, the 36-year-old husband of Ivanka Trump for around seven minutes read prepared remarks on technological innovation.
"Together we have set ambitious goals and empowered inter-agency teams to tackle our objectives. It's working and it's very exciting," he said.
The Trump impersonator on comedy show Saturday Night Live affectionately described him "a little Jewish Amelie," after the close-lipped and impish star of the eponymous French film.
In the first days of his administration, Trump appeared to believe there was no challenge too confounding, no conflict too intractable for his son-in-law to tackle.
Kushner is often seen standing beside Trump in the Oval Office or climbing the steps of Marine One but rarely heard beyond the corridors of power in Washington.
Hardline conservatives in the White House have long seen Ivanka and her husband Jared Kushner -- also a real estate developer -- as "New York progressives" trying to bend the volatile president to their way of thinking.
Spokesman Sean Spicer on Monday announced that Kushner would soon go to the Middle East on the latest peace drive, meeting leaders Benjamin Netanyahu and Mahmud Abbas.
