* Items marked with an asterisk (*) default to 0, meaning a server default: the default is set in the configuration file used by the ASRaaS engine instance. The values shown here are the values set in the sample configuration files (default.yaml and development.yaml) provided with the ASRaaS engine. In the case of max_hypotheses, the default (10 hypotheses) is set internally within ASRaaS.
