	parameters (RecognitionParameters)
		language		Mandatory, for example, en-US
		topic		GEN
		audio_format (AudioFormat)		Mandatory, for example, PCM

			suppress_call_recording	False: Log calls and audio
			mask_load_failures	False: Loading errors for any resource end recognition
			allow_zero_base_lm_weight	False: Base LM uses minimum 10% resource weight
		no_input_timeout_ms		0*, usually no timeout
		recognition_timeout_ms		0*, usually no timeout

	resources (RecognitionResource)
		external_reference (ResourceReference)
			type (Enum ResourceType)	Mandatory with resources: external_reference
			uri	Mandatory with resources: external_reference
			mask_load_failures	False: Loading errors (wordsets only) end recognition
			request_timeout_ms	0*, usually 10000 ms or 10 seconds
			headers	Empty
		inline_wordset		Empty
		builtin		Empty
		inline_grammar		Empty
		wakeup_word		Empty
		weight_enum (EnumWeight)		0, meaning MEDIUM for DLMs and builtins, LOW for wordsets
		weight_value		0, meaning 0.25 for DLMs and builtins, LOW for wordsets
		reuse (EnumResourceReuse)		LOW_REUSE: only one recognition
	client_data			Empty
	user_id			Empty
control_message (ControlMessage)				Empty
audio				Mandatory

* 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.
