Virtual Assistant



Virtual Assistant Diagram

Customers and partners have a significant need to deliver a conversational assistant tailored to their brand, personalized to their users, and made available across a broad range of canvases and devices. Continuing Microsoft’s open-sourced approach towards the Bot Framework SDK, the open-source Virtual Assistant solution provides you with a set of core foundational capabilities and full control over the end user experience.

Owning and enriching customer relationships and insights is vital to the goals of the Virtual Assistant. You can modify the name, voice, and personality to suit a customer’s needs. The solution simplifies the creation of a Virtual Assistant, enabling you to get started in minutes and extend with end-to-end development tooling.

Common scenarios are provided as reusable conversational Skills, increasing developer productivity and enabling a vibrant ecosystem of reusable scenarios. Individual Skills can be added to an existing conversational application like: finding a point of interest, checking off an item on a to-do list, or replying to an email. Skills are fully customizable and consist of language models for multiple languages, dialogs, and code.

Example Scenarios

The Virtual Assistant extends across a broad number of industry scenarios, some example scenarios are shown below for reference purposes.

  • Automotive Industry
    • Voice enabled Virtual Assistant integrated into the car providing end users the ability to perform traditional car operations (e.g. navigation, radio) along with productivity focused scenarios such as moving meetings when your running late, adding items to your task list and proactive experiences where the car can suggest tasks to complete based on events such as starting the engine, traveling home or enabling cruise control. Adaptive Cards are rendered within the Head Unit and Speech integration performed through Push-To-Talk or Wake Word interactions.
  • Hospitality
    • Voice enabled Virtual Assistant integrated into a hotel-room device providing a broad range of Hospitality focused scenarios (e.g. extend your stay, request late checkout, room service) including concierge and the ability to find local restaurants and attractions. Optional linking to your Productivity accounts open up more personalized experiences such as suggested alarm calls, Weather warnings and learning of patterns across stays. An evolution of the current TV personalization experienced in room today.
  • Enterprise
    • Voice and Text enabled branded Employee Assistant experiences integrated into enterprise devices and existing conversation canvases (e.g. Teams, WebChat, Slack) enabling employees to manage their calendars, find available meeting rooms, find people with specific skills or perform HR related operations.

Our Principles

Your Data, Brand, and Experience

All aspects of the end user experience are owned and controlled by you. This includes the Branding, Name, Voice, Personality, Responses and Avatar. The source-code to the Virtual Assistant and supporting Skills are provided in full enabling you to adjust as required.

Your Virtual Assistant will be deployed within your Azure subscription. Therefore all data generated by your assistant (questions asked, user behavior, etc.) is entirely contained within your Azure subscription. See Cognitive Services Azure Trusted Cloud and the Azure section of the Trust Center more specifically for more information.

Write Once, Embed Anywhere

The Virtual Assistant leverages the Microsoft Conversational AI platform and therefore can be surfaced through any Bot Framework channel – e.g. WebChat, FaceBook Messenger, Skype, etc.

In addition, through the Direct Line channel we can embed experiences into Desktop and Mobile Apps including devices such as Cars, Speakers, Alarm Clocks, etc.

Enterprise Grade Solutions

The Virtual Assistant solution is built on the Azure Bot Service, Language Understanding Cognitive Service, Unified Speech along with a broad set of supporting Azure components meaning that you benefit from the Azure global infrastructure including ISO 27018, HIPAA, PCI DSS, SOC 1, 2 and 3 certification.

In addition, Language Understanding support is provided by the LUIS Cognitive Service which supports a broad set of languages. The Translator Cognitive Service provides additional Machine Translation capabilities to extend the reach of your Virtual Assistant even further.

Flexible Integration and Contextually Aware

The Virtual Assistant architecture is flexible and can be integrated with existing investments you have made into device-based Speech or Natural Language processing capabilities and integrate existing back-end systems and APIs.

Not only does the Virtual Assistant enable you to deliver your own unique experience, but you can also handoff a user’s query to their chosen Digital Assistant for certain types of questions.

Your Virtual Assistant can be integrated into your device and ecosystem to enable a truly intelligent experience. Through this contextual awareness your Virtual Assistant can deliver a further personalized conversation than otherwise possible.

Adaptive Cards

Adaptive Cards provide the ability for your Virtual Assistant to return user experience elements (e.g. Cards, Images, Buttons) alongside text-based responses. If the conversation canvas has a screen these cards can be rendered across a broad range of devices and platforms providing supporting UX where appropriate. Samples of Adaptive Cards are available to try out, as well as documentation on how to render cards within your own application.


In addition to the core Virtual Assistant, there exists a broad set of common capabilities which require each developer to build themselves. Productivity scenarios are a great example where each organization would need to create their own:

  1. Language Models (LUIS)
  2. Dialogs (code-based)
  3. API Integration (code-based)
  4. Language Generation (bot responses)

This is then further complicated by the need to support multiple languages and results in a large amount of work required for any organization building their own assistant. Our Virtual Assistant solution includes a new Skill capability enabling new capabilities to be plugged into an existing Virtual Assistant through configuration only.

All aspects of each Skill are completely customizable by developers as the full source code is provided on GitHub along with the Virtual Assistant.
