|`inputs`|The plain text or SSML to be synthesized.<br/><br/>When the `inputKind` is set to `"PlainText"`, provide plain text as shown here: `"inputs": [{"text": "The rainbow has seven colors."}]`. When the `inputKind` is set to `"SSML"`, provide text in the [Speech Synthesis Markup Language (SSML)](speech-synthesis-markup.md) as shown here: `"inputs": [{"text": "<speak version='\''1.0'\'' xml:lang='\''en-US'\''><voice xml:lang='\''en-US'\'' xml:gender='\''Female'\'' name='\''en-US-AvaMultilingualNeural'\''>The rainbow has seven colors.</voice></speak>"}]`.<br/><br/>Include up to 1,000 text objects if you want multiple audio output files. Here's example input text that should be synthesized to two audio output files: `"inputs": [{"text": "synthesize this to a file"},{"text": "synthesize this to another file"}]`. However, if the `properties.concatenateResult` property is set to `true`, then each synthesized result is written to the same audio output file.<br/><br/>You don't need separate text inputs for new paragraphs. Within any of the (up to 1,000) text inputs, you can specify new paragraphs using the "\r\n" (newline) string. Here's example input text with two paragraphs that should be synthesized to the same audio output file: `"inputs": [{"text": "synthesize this to a file\r\nsynthesize this to another paragraph in the same file"}]`<br/><br/>There are no paragraph limits, but the maximum JSON payload size (including all text inputs and other properties) is 2 megabytes.<br/><br/>This property is required when you create a new batch synthesis job. This property isn't included in the response when you get the synthesis job.|
