What are the 5 most renowned Android personal assistants based on AI? Check them out as follows:

  • Google Assistant. Released in May 2016, Google Assistant is arguably the best personal assistant app for Android.

Building an AI assistant app: Create a virtual assistant demo solution with the help of Dialogflow

Wondering how to build a smart personal AI assistant? If you want to personally make your own AI assistant for Android, try Dialogflow. It’s a simple service created by Google, known previously as Api.ai.

AI assistant app

This arguably the best AI for Android is used for deployment of various reaction scenarios to user requests and voice control. The created software can be deployed on a mobile device, on a website and even in some messengers (choose from 32 different options). Dialogflow is free (a corporate version is also available for the development of advanced Google Cloud solutions) and is a quite a sufficient option for the development of your debut AI software. Let’s break everything down into simple steps.

1 Step: new project initiation

The service is absolutely free and its only requirement is a personal Google account. Register or use existing account, then, go to the Dialogflow official website to create a new agent (basically, your to-be-created assistant) by entering its name (leave other fields unchanged if you like). If you aren’t registered in Firebase, you’ll also have to create a separate project there. Click the “Create” button and view console.

2 Step: connecting the prebuilt agents.

Viewing the console, you’ll notice the prebuilt agents in the menu panel, each dedicated to its own task. Click “Prebuilt Agents”, choose the agent and click “Import”. Note that the agents only recognize English speech by default. In order to customize language configurations, open the “Languages” tab, choose the language and save changes. To enable a possibility to interact with the agent in your native language, click the respective checkbox and you will view “Intents”.

3 Step: teaching the newly-created agent

Open an “Intents” menu. Now, you have to choose the required menu item which represents your agent’s action in response to user request. You can work through quite many scripts and setup the maximum number of user commands in “User says” section. Upon entering commands, you’ll be offered the possible variants of an answer which must be remembered.

4 Step: testing an assistant.

Now, click the “Try it now” tab to test your agent’s performance. The in-depth aspects of this process are described in more detail in the respective documentation. Otherwise, if you simply don’t want to get into API codes, you can conduct an analysis of the newly-created bot’s scripts with the help of cURL requests (the query text you enter must be URL-encoded and the request must include a key, which is automatically assigned to each new agent).

5 Step: transferring all scripts to JavaScript.

Now, you’ll have to program a little. In order to understand where and how to start everything off, let’s review your agent’s working algorithm once again. For instance, your assistant is summoned to call up the requested phone book number.

The following actions must be defined in the JavaScript code:

  1. User greetings upon launch

  2. Recognition of a user request via mobile device microphone

  3. Analysis of the request by the agent to indicate whether there was a “Call up” topic mentioned (a user is asked to paraphrase the request if incorrectly pronounced)

  4. If a “Call up” topic is mentioned in the request, the agent searches for the required contact in contacts (if it isn’t found, the agent informs a user about it).

  5. Having found the required number, the agent launches a call function

6 Step: creating a full-blown application.

You’ll need to create a full-scale application in order to finish your project. You can do it via SDK for Android Voximplant. After it’s done, all that’s required of you to do is connect the previously-created script to JS. That’s it, your AI-based assistant is ready!

This is only one of the ways to implement private simpler personal assistant apps. You can employ any other software solutions for Android, such as Wit.ai or Clarifai as well.
