I am trying to do some test using the Google Speech API but from outside Google Cloud. In the older beta version I was able to specify a credentials file but now I am unable to find this option in the SpeechClient class.

How can I go about specifying the authentication keys using the Google Speech API Java library? I believe a sample code should be added to demonstrate this (both passing flat credentials and using a credentials file)

P.S I already asked the same exact question on SO but 4 days later and still no one answered
