There is no truth that the VOX survey application is a cellphone based system that is using text to do field work.
VOX Survey application uses Computer Assisted Personal Interview (CAPI) method. As you can see in the methodology of PAHAYAG, we did face-to-face interviews just like Pen and Paper Interview (PAPI), the only difference is:
- Field work days has been shortened
- Real time transmission of results/responses
- Encoding was bypassed
