How to Create Virtual Assistant Apps like Siri and Google Assistant

Independent services to make your own voice assistant

The above technologies are not the only alternative for adjusting voice management in your app. There are numerous tools for developers who are keen on machine thinking. For your reference, I have arranged a list of the most notable ones. Both mobile and web services are included.

Melissa

Melissa is a real finding for the newcomers in development who want to create a custom voice assistant. The whole system consists of many parts. So, in case you want to add or modify a certain feature, you can do it without changing a complete algorithm.

Melissa can speak, take notes, read news, upload pictures, play music, and do many other things. Written in Python, it works on OS X, Windows, and Linux. The web interface is developed with the help of JavaScript.

Jasper

Jasper would be suitable for those who prefer to program the biggest part of artificial intelligence without the external support and create the custom AI assistant relying on themselves. It is also a great tool for the Raspberry Pi fans because it runs on it’s Model B.

Jasper is written in Python. It can listen and learn. The first capability is introduced by the active module, the second – by the passive. Always being on, it is ready to perform the tasks at any moment of day or night. Silently studying your habits, it can provide you with the precise information just in time.

So, if you want to build your own voice assistant, you should consider Jasper. 

Api.ai

Api.ai covers a wide range of tasks allowing to make your own personal assistant. Along with voice recognition, it also supports converting voice into text followed by the execution of the relevant tasks. Analyzing and drawing conclusions isn’t alien for this service either.

Api.ai has both free and paid versions. The last one enables working in a private cloud. So, if privacy is your priority, this is just what you need.

Api.ai provides a wide range of APIs including iOS, Android, Windows Phone, Cordova, Python, Node.js, Unity, C#, and others.

Wit.ai

Wit.ai is similar to Api.ai service. There are two elements to set up in your app if you want to use it – intents and entities. Similar to the Siri system, intent stands for the action that a user wants to perform, e.g., show the weather. Entities clarify the characteristics of a given intent, e.g., the time and place of a user.

One pleasant thing is that you don’t need to create the intents on your own. Wit.ai provides the developers with a long list to choose from. Another piece of good news is that it is totally free both for public and private usage. However, to create your own personal assistant with the help of Wit.ai, you should follow it’s terms.

As well as Api.ai, Wit.ai introduces a variety of APIs for iOS, Android, Ruby, Python, Windows Phone, C, and Raspberry Pi developers. Frontend developers will be delighted with the fact that it also has a plugin for JavaScript. It’s a great solution to create a voice assistant for various platforms.
