In this article, I will explain how you can create a virtual voice assistant for websites and VR-AR apps. Hootsy is an online service where you can build voice interactive assistant without any coding. Unlike regular voice assistants, this is a virtual voice assistant with an avatar that has a body language. It has various animations to mimic human-like reactions like blinking, pose, waving, talking, etc. You can personalize all these actions along with the appearance of the assistant and then chose the conversation source and your data. If you already have a Facebook chatbot, you can easily turn that into a voice interactive assistant within a few minutes.

After creating the virtual voice assistant, this website gives you an embed code along with ID and token which you can use to add the assistant to a website or augmented reality and virtual reality apps. Hootsy also provides web and Unity SDK along with documentation to further help you deploy the assistant. The free plan allows 500 requests per month thereafter you can pay as you go that costs $0.015 per request.

Creating a virtual voice assistant on Hootsy is a simple and straightforward process. First of all, you need an Hootsy which you can create for free by signing up with either Google account or email. Once the sign up completes, log in to Hootsy. This website takes you to the Studio where it gives you an assistant character on the right and resource panel on the left.

The assistant character has a mic button which you can use to interact and test the assistant. On top, it shows what the assistant is doing at the movement e.g. looking, listening, talking, etc. At the bottom right corner, there is an AR button which opens the assistant in an augmented reality environment on supported devices.

The left side resource panel asks you to enter a name and description for the assistant. It also contains buttons to share the assistant and to get the embed code along with ID and token.

  • Skin Tone
  • Hair Color
  • Eye Color
  • Lip Color
  • Shirt Color
  • Pants Color
  • Shoe Colors

Then, you can choose a voice for the character from the given option and set the character scale (size).

  • Talk Animation
  • Blink Morph Animation
  • Idle Animation
  • TPose Animation

Conversation is the main part of the assistant. This website supports multiple methods to add conversation data for the assistant. Here are all the supported sources you can choose from:

  • Prebuilt (covers Visuals Test and Small Talks)
  • Dialogflow (connect to Dialogflow using Dialogflow access token)
  • AWS Lex (connect to AWS Lex by adding Lex Bot info)
  • Custom (to use custom webhooks)

Apart from all these options, you can also upload your conversation model(s) to the assistant in the form of GLTF files.

The last section on the resource panel is Gallery where you can add photos that you want to use with the assistant.

Once the assistant is ready, you can copy the embed code from the resource panel and add that to your website to embed the assistant there. In the case of AR and VR apps, it gives you ID and token which you can implement in your app and embed the assistant.
