See the discussion in the link on the speech integration below. Currently using the Survey 123 Application form the google play store, there is no talk to text availability in the app to add to text fields and also no Swype availability,. Please enable support to allow the app to work the same way eth browser surveys work when entering survey information on androids. As noted below in the link -it appears the development of the app needs to support the talk to text button and Swype for Gboard on Android devices.
