Mrs.Sruthi
Your son’s 2nd cusp fell in an airy sign Aquarius. The sub lord Mercury is in 2nd house but it is in a watery sign. Because of watery sign connection, he will not show interest to speak as others do.
Current dasa is of Jupiter and bhukti is of Venus upto 9-7-2026. Jupiter is signifying Mercury in 2nd house (Jupiter is deemed to be in conjunction with Mercury as both have same star and sub). Jupiter is Ketu sub in 2nd house, that Ketu signifies Saturn in 10th a watery sign. Bhukti lord Venus is in earthy sign in the star of Sun in 2nd house and sub of Rahu who signifies Moon in an airy sign. So Venus bhukti will definitely give improvement in speech. But because of watery sign connections, he will not show interest to speak.
Saturn period is good for him. He will complete his education and get a job also.
Good Luck
