Intelligent Virtual Assistants Market Insights

Intelligent Personal Assistants (IPA), often referred to as Intelligent Virtual Assistants (IVA), are AI-powered agents that can provide tailored replies by drawing on contexts like client metadata, previous interactions, knowledge bases, geolocation, and other modular databases and plug-ins. According to Mordor Intelligence, the market for intelligent virtual assistants, which grew quickly in the 2020s, is expected to reach USD 6.27 billion by 2026.

In many aspects, AI assistant technology is comparable to a conventional chatbot, but it also incorporates data science, ARVR, and next-generation analytics. While traditional chatbots are capable of answering questions using Markov chains and other similar techniques, the dynamic insights produced by intelligent virtual assistants much outweigh their static replies.

Apple’s Siri, a consumer-facing device marketed as a personal assistant, is one of the most well-known virtual assistants. Other IVAs include Google’s Assistant, Amazon’s Alexa, and Cortana from Microsoft. Siri and its rivals make it simple for users to carry out voice requests by automating routine operations like setting alarms on smartphones, reading out emails aloud using text-to-speech software, playing and searching for music, and sending text messages. The introduction of intelligent personal assistant technology by automobile manufacturers was prompted by the pervasiveness and popularity of IVAs in consumer smartphones.

With significant development in the healthcare, technology, and finance sectors, the Asia Pacific area is an important market to monitor for intelligent virtual assistants. 

Apple Inc., Inbenta Technologies, IBM Corporation, Avaamo Inc., and Sonos Inc. are some of the major players in the sector.

The healthcare, telecommunications, travel & hospitality, retail, and BFSI industries are among the end-users of AI assistant technology. Smart speakers, cellphones, automobiles, trucks, home computers, home automation devices, and many more consumer goods use IVAs or IPAs.

IVAs and IPAs rely on underlying technologies such as machine learning, cognitive computing, text-to-speech, voice recognition, computer vision, and augmented reality. Later, we’ll go into greater depth about them.

Why Do Companies Create AI Assistants?

If you possess an Apple device, it’s likely impossible for you to picture life without Siri. The majority of large companies are making investments in the creation of AI assistants, like Amazon Alexa, Google Assistant, and Samsung Bixby. So why do businesses act in this way?

The primary benefit of employing artificial intelligence to develop such solutions is that it can rapidly and effectively evaluate enormous volumes of data, uncover patterns, and generate insightful recommendations. AI assistants that use voice and speech recognition make it much simpler to complete numerous daily chores like adding events to your calendar, creating a reminder, or keeping track of your monthly costs. By 2024, more than 8 billion digital voice assistants will be in use globally, approximately equal to the world’s population.

The key benefits of building virtual assistants for business include the following:

The reduction in the volume of calls and service requests to human agents while improving customer assistance. You may automate the customer interaction process in business with the help of AI assistants. Your staff will be able to concentrate on more difficult work as a result of not wasting time on requests that can be handled automatically.

important data collecting is simple. Analysts must go through many hours of phone conversations and information gathered and recorded by a live customer care person in order to acquire customer experience data from traditional support calls or chats. IVAs allow customer support agents to quickly file away and categorize client inquiries and related metadata for analysis without having to worry about making accurate notes.

An individualized user experience. The great level of customization offered by AI assistants allows them to adjust to the demands of each user. For instance, IPAs are capable of remembering both the user’s preferences and name. This enhances client loyalty and happiness while also increasing user engagement.

One of the main benefits of intelligent virtual assistants is that businesses may assemble customer support and complicated components of their corporate toolchain like Lego bricks. A virtual assistant may be modified to plug into any database or resource to deliver essential data and enhance workflow at any level.

Types of AI Virtual Assistants

Chatbots, voice assistants, AI avatars, and domain-specific virtual assistants are just a few of the several forms of AI virtual assistants.

Since their creation, chatbots have been a fixture of the e-commerce industry, but contemporary versions are driven by artificial intelligence, allowing them to consider client questions rather than forcing the user through a series of static events.

Voice assistants, like the well-known Siri and Google Assistant programs, employ automatic voice recognition and natural language processing to provide vocal answers to questions.

Artificial intelligence (AI) avatars are 3D models created to resemble people and are used for entertainment purposes or to provide a human touch to virtual customer service interactions. Modern technology from firms like Nvidia is able to create remarkably lifelike human avatars in real-time. 

Domain-specific virtual assistants are highly specialized AI virtual assistant implementations created for extremely specific businesses. They are geared for excellent performance in demanding areas like travel, banking, engineering, cybersecurity, and others.

The Technology behind AI Assistants

Consider the scenario where you wish to develop a Siri-like virtual assistant. What method would you use to create it? You could immediately incorporate Siri into your application, which would be your first and perhaps easiest choice. Three popular artificial intelligence (AI) assistants that many developers include in their apps are Siri, Cortana, and Google Assistant. The SiriSDK development kit was introduced by Apple Inc. in 2016 and allowed developers to include app features such as “Tasks” that Siri could do. The user intents are referred to as “Intents” by SiriSDK, and Intents are connected to special classes and attributes.

Speech-To-Text (STT) and Text-To-Speech (TTS) 

In order to qualify as intelligent virtual assistants, they must at the very least have Text-to-speech (TTS) and Speech-to-text (STT) capabilities. 

Apps can translate spoken words into digital signals using speech-to-text technology. This is the procedure. When you talk, many vibrations are produced. The program turns them into digital signals using an analog-to-digital converter (ACD), extracts sound from them, segments them, and matches them to preexisting phonemes. The smallest linguistic element that may discriminate between the sound bases of various words is called a phoneme. The algorithm builds a text representation of what you said by comparing these phonemes with certain words and phrases using intricate mathematical models.

The opposite is true with text-to-speech. Text is translated into speech output using this technique. TTS is a machine learning-based reproduction of human speech from text. To translate text to speech, the system needs to go through three processes. The system must first translate text into words, then carry out phonetic transcription, and finally translate transcription into speech. 

To enable smooth and effective communication between users and apps, virtual assistant technology uses speech-to-text (STT) and text-to-speech (TTS). You also need to provide the software with the capacity to understand user requests using intelligent tagging and heuristics in order to transform a simple voice assistant with static instructions into a true AI assistant. 

Noise Control

Another essential component of a voice assistant’s accuracy is noise management. You can’t assume that all of your consumers will have a smartphone with software-based noise control and suppression features, despite the fact that many do. Top-tier Bluetooth headsets come with hardware noise cancellation to make up for the absence of onboard noise cancellation software, but there is still no assurance that your AI assistant will be able to understand what your clients are saying in a crowded train car. You reduce the possibility of misinterpreting voice requests by implementing internal noise control programs. 

Speech Compression

Unless you want to keep all speech data locally on the customer’s hard disk, your AI assistant will also need to store voice data, if only momentarily, for processing. Although speech compression is essential, developers must tread carefully when using compression. It is possible to compress an audio file to the point where significant quantities of quality are lost, making it challenging or impossible to reconstruct what was spoken while the file was being processed. Although compression technology is continuously advancing, when creating your voice assistant, audio codecs and compression solutions are worth carefully researching.

Natural Language Processing (NLP)

Once you receive the speech data, the AI assistant must use Natural Language Processing (NLP) to evaluate and understand the data before executing the desired instruction. The voice recognition process is made easier by NLP. Even if a lot of AI kits have been pre-trained on many hours of speech samples, you still need adequate consumer data to fine-tune the precision for your use cases. If you want your AI assistant to answer vocally, you’ll need a speech synthesis system like the top-tier one from Google Cloud, which creates natural-sounding voices. 

Speech processing, however, is insufficient to determine a person’s true purpose and to carry on a typical conversation. Natural Language Understanding is used to ensure that the request is correctly interpreted.

Natural Language Understanding (NLU)

Most computer and data scientists see Natural Language Understanding (NLU), a distinct approach to Natural Language Processing (NLP), as a subfield of NLP. NLU interprets the natural language without standardizing it and derives meaning from queries by determining the context, in contrast to NLP approaches that parse, tokenize, and standardize natural language into a standardized structure for command processing. In a nutshell, NLU looks at the true purpose behind the question, whereas NLP evaluates grammar, and structure, and corrects user spelling mistakes.

Natural Language Generation (NLG)

Natural language output results from natural language production. With the use of this technology, chatbots and virtual assistants may respond to consumers in a way that is human-like. The models and techniques utilized for NLG might vary and rely on the objectives of the project and the methods employed for development. A template system, which can be used for texts with a fixed structure and little data to be filled in, is one of the simplest methods. With this method, these gaps may be automatically filled in with information taken from a spreadsheet row, a record in a database table, and other sources. 

Another strategy is dynamic NLG, which allows the system to respond on its own without the developer having to create code for every edge situation. This form of natural language creation is more sophisticated and is based on machine learning techniques.

Deep Learning

The complexity of text-only chatbots is far lower than that of voice assistants. When building a chatbot, you take out a lot of tools since you don’t have to translate speech into text for interpretation. The ability of next-generation text generation, like GPT-3, to generate whole news items from a “seed” extends beyond only providing answers to simple questions. Deep learning enables it. 

Augmented Reality (AR)

For a more immersive experience, augmented reality enables you to overlay 3D things in the actual environment. Great examples of applying this technology include AR-based mobile chatbots and AR avatars. 

Generative Adversarial Networks (GANS)

Generative Adversarial Networks are neural network-based algorithmic structures that provide fresh examples of synthetic data. To create a realistic 3D face for AI avatars and 3D helpers, GANs use actual picture samples and generators that are fed into discriminators. 

The technique has been used to produce lifelike human models in various video games and other items. GANs may also be used to create full-depth 3D images from still pictures. Nvidia’sOmniverse Avatar Project Maxine, which produces a lifelike real-time animation of a human face reciting a text-to-speech sample, is possibly the most advanced implementation of AI avatars to date.

Emotional Intelligence (EI)

Body language and human emotions matter more than the speech when it comes to AI avatars or 3D virtual assistants. IPAs may detect a user’s nonverbal behavior in real time while talking and respond appropriately thanks to emotional intelligence enabled by AI. Emotion AI, which tracks facial expressions, body language, and voice to track human emotions, will help virtual assistants be more responsive as a result of this.

We should also include interpreting speech for emotion. Such software examines both the content and delivery of human speech. The algorithm accomplishes this by extracting paralinguistic elements that aid in recognizing variations in loudness, tone, and pace and translating these into human emotions. 

Steps to Develop a Successful AI Assistant

Google Assistant is one of the most well-known instances of artificial intelligence (AI) assistants, which have grown in popularity in recent years. Voice-activated artificial intelligence (AI) assistant Google Assistant can do a variety of things, including playing music, creating reminders, and answering inquiries.

Several techniques, including crowdsourcing, web data scraping, and leveraging pre-existing datasets, may be used to gather and tag data. To effectively train your machine learning algorithms, you must identify your acquired data after you have it.

Build Natural Language Processing Models

A key element of AI helpers like Google Assistant is natural language processing (NLP). Your assistant can comprehend user queries in plain language and reply to them thanks to NLP models. Machine learning algorithms that can decipher and comprehend the structure of language must be used to create NLP models.

Transformers, recurrent neural networks (RNNs), and convolutional neural networks (CNNs) are some of the NLP models that are accessible. The model that best meets your demands must be chosen because each one has advantages and disadvantages.
