 Batch synthesis properties can be grouped as: avatar related properties, batch job related properties, and text to speech related properties,  which are described in the following tables.
 
-Some properties in JSON format are required when you create a new batch synthesis job. Other properties are optional. The batch synthesis response includes other properties to provide information about the synthesis status and results. For example, the `outputs.result` property contains the location from where you can download a video file containing the avatar video. From `outputs.summary`, you can access the summary and debug details.

 ## Custom text to speech avatar
 
 You can create custom text to speech avatars that are unique to your product or brand. All it takes to get started is taking 10 minutes of video recordings. If you're also creating a custom neural voice for the actor, the avatar can be highly realistic. For more information, see [What is custom text to speech avatar](./what-is-custom-text-to-speech-avatar.md).
