10:33	ka pynlong ia ki workshops da kaba pyndonkam da ki spoken tutorials.
10:36	Ka ai certificates sha kito kiba pass ha ka an online test.
10:40	Ia ka jingtip ba kham bniah , sngewbha ban thoh sha ka contact@spoken-tutorial.org
10:48	Ka Spoken Tutorial Project ka dei shi bynta jong ka Talk to a teacher project.
10:52	La kyrshan ia ka da ka National Mission on Education lyngba ka ICT, MHRD, Government jong ka India.
10:59	Ia ka jingtip ba kham bniah halorkane ka mission lah ban ioh na kane ka link.
