# applied individually to specific RPCs. See
# {::Google::Cloud::Speech::V1p1beta1::Speech::Client::Configuration::Rpcs}
# for a list of RPCs that can be configured independently.
#
# Configuration can be applied globally to all clients, or to a single client
# on construction.
#
# @example
#
# # Modify the global config, setting the timeout for
# # recognize to 20 seconds,
# # and all remaining timeouts to 10 seconds.
