For details on supported google.longrunning methods, see the RPC and REST documentation.


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.
