Automation of Audio Injection ,Streamed audio

Use case is to automate the Google Allo testing for definite/specific queries like (what is 3* 3) which involves automating the audio injection ,Audio streaming and Recording the audio Output Response from Google ALLO

Does Appium has any API to enable the automation of Audio injection,Audio Streaming, and recording /playback of the audio response.

I don’t think there are any API’s for audio/video related stuff(If there are Appium dev should highlight it in features).

I got the use case you want to test, but may I ask you which app you really want to test Google Allo or An app you have some similar to Allo build by your organization.
