Software that converts text into speech is called a _____.

• A. Audio mixer
• B. Text reader
• C. Speech translator
• D. Voice synthesizer

Answer: (D)

Text-to-speech software converts written text into spoken words, so the best label for this kind of program is voice synthesizer. It describes the process of synthesizing a voice from text. An audio mixer is used to blend multiple audio tracks, not to generate speech. A text reader might read aloud, but it isn’t the standard technical term for converting text to speech. A speech translator changes spoken language to another language, which isn’t about producing speech from text. So voice synthesizer directly captures the idea of turning text into an artificial voice.
