Answer:
(B) Speech synthesis
Explanation:
Speech synthesis is technology that enables the conversion of data in text form to data in audio format. In a speech synthesis application, users input data in the form of simple texts and the application converts it into its corresponding sound output. It is also called text-to-speech.
I imagine that Heidi will have to type the articles into the speech synthesis system which in turn converts it into an audio. Then, of course, before submitting the articles for printing, she will have to listen to them.
Speech recognition on the other hand is used for doing the exact opposite of speech synthesis in that it allows a machine to identify and convert spoken language into texts. This is also called speech-to-text. The machine receive audio inputs and convert them to machine readable formats.
