- What it is
- Google Cloud's description of the speech begin and speech end events a streaming session can send, and of the timeouts that can close a stream.
- How much weight it carries
- Official documentation for the streaming configuration. The event timing depends on Google's own voice activity detector, which the page does not describe in detail.
Facts taken from this source
- Google Cloud sends a speech activity end event when it detects that speech has ended, and no such event is sent if the stream closes first.
