ListOperations
In order to return V2 operations, the RPC Operations.ListOperations
method
must be called with the filter value set to: is_v2(true).
Operation ID
All Speech-to-Text V2 operations have a unique_id in the name
field
that starts with v2-. This makes it easy to discern between Speech-to-Text
V2 and V1 operations.
