That’s why it’s important to design your voice assistant to provide a better user experience. However, this requires an effective voice interface design.

  • Ask the necessary question. It’s important to keep questions simple, so consider asking what’s necessary to accomplish the user’s request. For example, instead of asking users to provide their name, address and other personal details to look up flight information for the flight they recently booked, ask for only the information that’s necessary to verify that the identity of the speaker. This helps to enhance the user experience and reduce the chances of creating a frustrating moment with your voice assistant.
  • Create dialogue examples. Anticipate the path of the conversational flow by writing out potential scenarios in the form of a dialogue. For example, you can create an example script of how the user may interact with your voice assistant when trying to get directions to the closest hospital. Use the help of conversational designers to suggest different responses your voice assistant can provide to answer questions.
  • Offer help. Sometimes users don’t know what they need. That’s where your voice assistant can lend a helping hand. Design your voice interface so that it inherently cues your voice assistant to offer help when the user pauses too long between questions.
  • Understand the “why” behind the behavior. By knowing why your users need your voice assistant’s help, you can better design a voice interface that speaks to their needs.
  • Leverage prototyping tools. Prototyping tools help you test your concept before you finalize your product so you can discover and fix any issues in your voice interface design. For instance, you can use Botsociety to create a voice assistant for several platforms, such as Alexa or Google. You can prototype and preview it to test the conversational experience users may have.
