| 09:40 | Measure/thew ia ki jingjngai jong ka perpendicular. |
| 09:44 | Ka output jong ka Assignment ka dei ban long kumne. |
| 09:48 | Peit ia ka video kaba lah ban ioh na kane ka url: http://spoken-tutorial.org/What is a Spoken Tutorial |
| 09:51 | Ka batai lyngkot ia ka Spoken Tutorial project. |
| 09:53 | Lada phim don ia ka bandwidth kaba biang , phi lah ban download bad peit ia ka. |
| 09:58 | Ka Spoken Tutorial Project Team : |
| 10:00 | ka pynlong ia ki workshops da kaba pyndonkam da ka spoken tutorials. |
| 10:03 | Ka ai certificates sha kito kiba pass ia ka online test. |
| 10:06 | Ia ki jingtip ba kham bniah , sngewbha write/thoh sha ka contact@spoken-tutorial.org. |
| 10:14 | Ka Spoken Tutorial Project ka dei ka bynta jong ka Talk to a teacher project. |
| 10:18 | La kyrshan ia ka da ka National Mission on Education lyngba ka ICT, MHRD, Government jong ka India. |
| 10:25 | Ia ki jingtip ba kham bniah halor kane ka mission lah ban ioh na kane ka link. |
| 10:29 | La pynkylla ia ane ka script da I Ribajanai wankhar, signing off . Khublei Shibun ba phi lah iasnohlang. |
