What is typically required to perform interactive voice response?

Interactive Voice Response (IVR) systems are designed to allow users to interact with a computer-operated phone system using their voice. This technology enables callers to navigate through menus, provide information, and receive responses without needing to speak directly to an operator. Voice recognition technology is essential to this process, as it allows the system to decipher spoken language and interpret user commands effectively.

Utilizing voice recognition allows for hands-free operation, making it convenient for users who may be driving or multitasking. This technology interprets the user's speech, which can include various commands or responses, to facilitate a more interactive experience. Therefore, the inclusion of voice recognition technology is what enables an IVR system to function properly and interactively.

Other options mentioned may include various methods of input or applications that are not specifically designed for voice-based interaction, making them less relevant for facilitating the primary function of IVR systems.
