I am researching ways to implement form filling via voice command given by user inside my application.I have searched two options but no one is seems useful and I am bit confused here.
First I tried with android voice to speech library integration.It gives me text but isn't smart enough to converse with as google assistance do.
Then second I tried to integrate google assistance with api.a. It provides the user conversation but it is like adding command to google assistance .It doesn't provide me voice to text data so that I can fill form and do further operation.
Please suggest me ways to implement.
You wouldn't use Actions on Google through Dialogflow for your implementation but rather the Google Assistant SDK which is meant for devices.
However, in your case it may make sense to use Dialogflow's Android client. You would not need to pull all of the Google Assistant's capabilities and the voice interaction would be limited to your own application.
