Online survey methods such as forms are one of the most used methods of survey. Many brands send these surveys to understand and analyse customer experience. 

Although this method has its fair advantages, they are often long and time-consuming. The responses are not usually detailed enough and customers would face survey fatigue, which leads to false responses and data. 

Voice surveys help avoid all these problems, the customer just has to talk! They feel more engaged and the responses are more refined because they talk to you directly!
