07:52 | Peit ia ka video kaba lah ban ioh na kane ka URL. |
07:55 | Ka pynlyngkot ia ka Spoken Tutorial project. |
07:57 | Lada phim don ia ka bandwidth kaba biang, phi lah ban download bad peit ia ka. |
08:02 | Ka Spoken Tutorial Project Team : ka pynlong ia ka workshops da kaba pyndonkam da ka spoken tutorials. |
08:06 | Ka ai certificates ia kito kiba pass ia ka online test. |
08:09 | Ia ki jingtip ba kham bniah , contact ia ngi ha ka contact@spoken-tutorial.org. |
08:16 | Ka Spoken Tutorial Project kadei ka bynta jong ka jingkren sha ki nonghikai project. |
08:19 | La kyrshan ia ka da ka National Mission on Education lyngba ka ICT, MHRD, Government jong ka India. |
08:25 | Ia ki jingtip ba kham bniah ha kane ka mission lah ban ioh na kane ka link. |
08:29 | La pynkylla ia kane ka script da i Ribajanai Wankhar bad nga dei u Thawlad miki na Meghalaya, signing off. Khublei ba phi lah iasoh. |
