@Parveen_Negi there have been some conversations about recording audio audits while enumerators are collecting data:
The concept is to record short snippets at random or fixed intervals. These can later be listened to to "spot check" interactions. @iamnarendrasingh is right that using this kind of feature may require participant approval depending on the laws of the country/region it is used in.
In order for such a feature to move forward, there will need to be thought given to how it is enabled and configured and any form specification changes. Of course, code will eventually need to be written as well. If this is an important feature for you, @Parveen_Negi consider starting to design how it will work and perhaps finding someone who will contribute the code.
