What is a Digital Assistant?

It is a voice assistant or a predictive chatbot that is programmed in such a manner that it can answer the queries of the user or can perform certain simple tasks. It is an advanced program that allows the user to simulate communication between the user and the system; the system should have an internet connection to perform these functions properly.

What is a Digital Assistant?

A digital assistant applies various advanced technologies such as Artificial Intelligence, natural language processing and understanding, and various machine learning algorithms to automate the software. Initially, the digital assistant is fed with information to perform various functions, but it also can learn from experience. The digital assistants can be personalized by analyzing the user's historical information, such as the personal details of the user, frequent searches, purchase preferences, or user interests.

The application can even answer complex queries and provide useful recommendations using all the above information. The machine learning algorithms enable the application to improvise by creating various new data models. The responsibility of the new data model is to identify the behavior of the present user and provide services according to it. It increases the efficiency of the digital assistant. 

There are various digital assistants that we use today. Some popular digital assistants are Google Assistant, which android users use. iOS users have Siri. Cortana is a digital assistant that is developed for Windows operating systems. Smart speakers such as Alexa are also an example of digital assistants.

Difference Between a Voice Assistant and a Chatbot

A chatbot is a comparatively similar program that can understand and respond to written or spoken conversations. It allows the person to communicate so that it seems that they are having a conversation with an actual person, but it only allows the user to perform simple conversations. There is a limitation to the queries they can answer and the function they perform.

For example, when you call a pizza outlet, your call is answered by a robotic voice that is a chatbot; it is responsible for instructing the user to order the pizza. The conversation required to place an order is called a simple conversation. Any other query that will be outside the domain of the chatbot will not be answered.

What is a Digital Assistant?

While a digital assistant is an advanced chatbot, which means that it is a chatbot with a wider domain and can handle more complex conversations such as making a train reservation, the user can provide a detailed description of the reservations, such as what should be the arrival time, seating preference, adding food. The user can also decide the transportation from the railway station and manage that with a single assistant.

What is a Digital Assistant?

The digital assistant will be required to go through various resources to perform all these functions. It is impossible to refer to numerous resources to perform a single task with a chatbot.

For easy understanding, it can be said that every digital assistant is also a chatbot, just a bit more complex, but not every chatbot is a digital assistant.

Functions Performed by a Digital Assistant

1. The famous digital assistants that can be accessed from your iOS and Android devices, such as Siri and Google Assistant, can answer numerous user queries. They can also recommend various activities and interests based on the user's previous searches. They can also automate certain tasks such as sending simple messages to the contact or dialing a phone number.

Also, they can perform complex tasks based on your routine, such as redirect you to a less congested road to reach your destination. The idea behind the intelligent home is to use this digital assistant to perform tasks such as regulating the house's temperature depending upon the time you will reach your place. If the user is leaving home for several days, it can also predict the temperature conditions of the destinations so that he can plan accordingly. The user can also use them to remotely access the home's smart devices, such as air conditioners or geysers.

2. They are not only useful at home but have various uses in the business as well. They provide a single platform to perform all the communication between a buyer and seller. A single platform makes it easier for the buyer to answer all the users from one place. Thus, increasing the effectiveness of the business. They are extensively used in customer contact centers to manage the incoming traffic and ensure that no queries go unanswered.

3. They are used to enhance the user service experience by automating certain processes. Using digital assistants to automate these tasks enables multiple users to use the service simultaneously. The user can automate simple tasks on the application using these digital assistants. It can be used to change the existing password and perform system checkups, and if there is an update, it can also update the system itself. It can also send alerts and notifications to the user. All these services can be done by the assistant and made available for the entire day.

4. The tasks performed by the digital assistant largely vary with the technology and the design of the assistant. The more complex the technology used, the more complex task it can perform. The quality of the natural language and Artificial Intelligence determines the services provided by the assistant.

Some of the functions performed by these assistants are:

5. In the IT industry, they are not only used for providing user services, but they can also automate certain processes that follow a procedure, such as resolving informational and transaction requests.

6. They are used to notify the users and send reminders to the employee about the scheduled tasks.

7. They can answer complex queries of the users that have multiple questions incorporated into a single one. To answer such queries, the assistant requires using multiple sources to meet all the user's requirements.

8. They can also be aligned with a business model, and a single assistant can interact with numerous business systems. They can be used to automate the process of sales, customer services, and marketing.

9. Some digital assistants can simultaneously manage the roles of a chatbot and an agent.
