If the Google Speech API transcribes audio at near real time, and my latency to the actual server is only 50ms, why do I receive my final streaming transcription result after 1.6s? Shouldn’t I receive it in only a couple hundred milliseconds?

Well, that is pretty generic. Can you be more specific? How are you calling the service, is your account free? – Guilherme Uzeda Oct 16 '18 at 11:36

You can refer to this [answer](https://stackoverflow.com/a/51359674/9908267). Apart from the transcription speed itself, authentication takes time every time a call is made to the API. – Yurci Oct 16 '18 at 12:09

Is it possible to avoid authenticating for each request? – Harry Stuart Oct 16 '18 at 12:10

You can use [API Keys](https://cloud.google.com/docs/authentication/api-keys) for authentication. Bear in mind with using the API Keys you lose the ability to track from whom the requests are being made and it might be easier for others to discover the key. – Yurci Oct 16 '18 at 12:19
