What does vocalizer mean?
A vocalizer is something that produces vocal sound, most often a device or software component that converts written information into speech. The term is frequently used in accessibility and assistive-technology contexts, where a vocalizer provides an audible voice for text displayed on a screen. It can also refer more generally to a person or instrument that makes vocal sounds, although vocalist is normally preferred for someone who sings professionally. In general contexts, the word is less common than speaker, voice, or speech synthesizer, but it is useful because it identifies the function rather than the type of device. Whether mechanical or electronic, a vocalizer turns some form of input into audible spoken language, allowing information to be conveyed without requiring the user to read it or another person to speak it.

The English agentive suffix -er was added to vocalize to form a noun naming a person or thing that performs the action of vocalizing.
