Synthesize Speech from Script.

Good for extensive content.

• Set sync field to false for asynchronous behaviour (no waiting for response, retrieve it later using GET method).

• Each Script section can have a separate configuration.

• Script sections are synthesized in parallel, you may use it to your advantage to increase time performance.

• Script sections that contain a media or sound effect tags are split into multiple files, as the media are rendered in /mastering. Similarly, a Script section containing only media tags will not be rendered here.

• Currently only wav format is supported in the output.
