Step-by-step explanation:
A Interactive Voice Response (IVR) system provides callers with a menu of options from which they can select by pressing a key on their telephone keypad. IVR systems use recorded voice prompts and touch-tone keypad entry to guide callers through the menu options.
For example, when you call a customer service helpline and are presented with a series of options like 'Press 1 for English, Press 2 for Sales,' that is an IVR system. You can press the corresponding key to select the desired option and be directed to the appropriate department or information.
IVR systems are widely used in various industries, including banking, healthcare, and telecommunications, to automate the handling of incoming calls, reduce wait times, and improve customer service efficiency.
