Remarks

With PromptBuilder, you can add a variety of content types to a prompt, including plain text, SSML markup (as a string or a file), recorded audio, or even another PromptBuilder object.

To append text to a PromptBuilder object and optionally control voice attributes such as emphasis, rate, and volume, use one of the AppendText methods. You can also control voice attributes as a group with the StartStyle and EndStyle methods.

You can append text and control what is spoken or how it is pronounced using the AppendTextWithHint, AppendTextWithAlias, AppendTextWithPronunciation, AppendSsml, or AppendSsmlMarkup methods.

Change the currently selected speaking voice in the prompt using one of the overloaded StartVoice methods, naming a specific voice to use or specifying required voice characteristics, such as age and gender.

To generate speech from a PromptBuilder object, you can pass it as an argument to the Speak method.
