Cloud Speech API Streaming recognition

[Ronald Ruijs]

Hello,

Now I got sync recognition working,I am trying to get streaming recognition to work.

I understand I need to make gRPC calls using protobuf data.

Unfortutely, I cannot use Google's Client Libraries, as they are not available for Delphi.

After reading the docs, I have some questions:

- Do I need to make a HTTP/2 call, or can I use HTTP/1.1 or WebSockets to call the rpc?

- Can I use an API key to authenticate?

Suggestions/ideas are highly appreciated. 

Best regards,

Ronald

Hi Ronald,

Based on gRPC documentation, gRPC uses standards based HTTP/2. For the second question, I should note that for APIs that don't require authentication like Cloud Speech API, you can use API keys.
