交互式语音应答（IVR，Interactive Voice Response）是一种基于电话的语音增值业务的统称。

电话用户只要拨打移动运营商所指定号码，就可根据语音操作提示收听、点播或发送所需的语音信息以及参与聊天、交友等互动式服务。

一些商业机构（如银行、信用卡中心、电讯商等）亦会透过交互语音系统 (Interactive Voice Response System, IVRS) 提供自动化电话查找服务，客户可拨打指定的电话号码，进入系统，根据系统之指示，键入适当的选项或个人数据，以听取预录之信息，或经电脑系统根据缺省的程序 (Call Flow) 组合数据，以语音方式读出特定的数据（如户口结余、应付金额等），亦可通过系统输入交易指示，以进行缺省的交易（如转账、更改密码、更改联系电话号码等）。

Interactive voice response (IVR) is a technology that allows a computer to interact with humans through the use of voice and DTMF tones input via keypad.

In telecommunications, IVR allows customers to interact with a company’s host system via a telephone keypad or by speech recognition, after which they can service their own inquiries by following the IVR dialogue. IVR systems can respond with prerecorded or dynamically generated audio to further direct users on how to proceed. IVR applications can be used to control almost any function where the interface can be broken down into a series of simple interactions. IVR systems deployed in the network are sized to handle large call volumes.
