AI Voice Vs Human Voice: Features That Distinguish Them

There are a lot of conflicts about the competition between AI voice vs human voice. In this article, we will discuss their distinctive characteristics and some benefits of AI voice that have made it common and have been trusted to be used in many fields like healthcare, advertising, and others.

Let’s explore the main interesting features of each voice below!

What Purposes The AI Voice Be Used?

AI voice is a product of Artificial Intelligence (AI) designed to generate natural and human-like voices to create speech synthetic.

The system is usually used to read news, and audiobooks, record readings for people with disabilities, or build virtual characters that can communicate through voices. 

Recently, AI voice has been applied widely to text-to-speech technology that is compatible with different fields and industries.

AI voice is applied to many areas of life.

There is no limit to how far AI voice can go as it has developed into human-like speech and is promised to advance higher. For instance, Steven Hawking’s voice is one of the most popular applications of text-to-speech technology with the help of AI voice. 

AI Voice Vs Human Voice: What Are Notable Key Differences?


The first difference between AI voice vs human voice is how they are produced. In fact, all we know is that AI can be made in a short time, while human voice is something that will be developed gradually in all their lifetime. 

Complicated algorithms and deep machine learning are how AI voice is born. On the opposite side, the human voice is grown through natural development with the contribution of human vocal apparatus like lungs, throats,…


One of the most notable distinctions between AI voice vs human voice is the ability to adjust. AI voice can easily change in speed, type, and intonation to fit the requirements. 

However, although AI voice is flexible, we have to admit that it can not be compared to natural voice regarding how fast human speech can change pitch, tone, and emotion based on surroundings. So, no matter how advanced AI voice has become, it can’t beat human voice in expression and naturalness.

Sentimental aspects

The human voices have a variety of sentimental aspects. Through intonation, pitch, and ways of pronunciation, the human voice can communicate the emotion and the underlying meaning that the AI voice is still unable to. 

Nevertheless, AI is still a hot topic for computer scientists and technologists to invest their time and effort in, so maybe it can exceed our expectations in this factor.


Imperfections are what makes the human voice perfect.

Although the human voice is imperfect, with many mistakes such as stutters, breathing sounds, and unclear pronunciation. But that is what contributes to the nature of the human voice. Besides that, the AI voice’s perfection and impeccability can distinguish it from the human voice.


People with human voices, through the use of language, can freely create wordplay like puns and jokes. They can even capture the nature of language through metaphors and analogies to deliver complicated concepts. 

Although AI voice has been trained with data from these kinds of language use, unluckily! The inventiveness and creativity of the human voice will forever leave AI behind.


The final but most crucial difference between AI voice vs human voice is uniqueness. As mentioned above, though it can copy from many sources of voice, it can never reach the level of personalization that a natural voice has. Each individual will possess a unique voice that can be used as a characteristic to identify them.

Although there are many improvements that AI voice has to make, it can still be a potential tool and assistance for people who can make the correct use of it. However, with the rapid advancement of technology, AI voice is believed to produce more astonishing breakthroughs.

How About The Benefits That AI Voices Offer?

Cost-reduction tool

When comparing the price between AI voice vs human voice, the outstanding perks of replacing AI voice will be shown clearly. In the past, the recording and voiceovers required considerable budget investment in human voice actors. 

However, with the development of AI voice nowadays, producing voice for any project will be more effortless and require fewer resources. This will enable companies and individuals to save production costs but still effectively attract customers.

Affirmed excellence

Another benefit when comparing AI voice vs human voice is consistent excellence. AI voice can maintain the same quality as required without interruption like the human one. 

Modern technologies have reached a level of deep learning model that can offer the same quality, intonation, and speed of the voice. Long projects that need confirmed excellence can generate outstanding results with the help of AI voice.

No language borders

One of the great advantages of AI voice is eliminating language borders. With the development of AI models, AI voice systems can read and pronounce in more than one language, not to mention millions. 

This opens a chance for enterprises and individuals to reach the global market without worrying about limited language competence. 

There is no limit to how many language AI voice can speak.

Faster production process

Using real human voice actors requires much time and hours for production. Moreover, humans cannot always be in their best condition, so the voice quality may vary. 

But, AI voice can speed up the process and offer unchanged competence. As a result, companies and organizations can enjoy faster production time, especially when they are in a hurry for an effective campaign and project. 

Moreover, shorter production time means less money and time spent on business. How convenient!

More room for creativity

Producers can freely make changes to the tone, gender, and pronunciation of AI voice so that it meets the requirements of the project within a short time. 

With this benefit of AI voice, producers can enjoy this freedom of creativity and faster-adjusting procedures.


We hope our article helped you clear up the controversial question “AI voice vs human voice: Which one is better?”, especially since the birth of AI.

AI voice can bring many benefits and advantages to businesses and individuals. Still, some restrictions stop AI voice from completely replacing the role of the human voice. As a result, it is up to users and the objectives of usage that will decide which method to use.


Can AI voice completely replace human voice? 

The answer is no. AI voice is not a competent rival to the human voice. In some contexts, AI voice seems to outsmart human voice, but when comparing the naturalness, the creativity of word use, and the ability to transmit underlying meaning through tone, pitch, and emotion.

Should voice artists beware of the potential replacement of AI voice?

In the meantime, there is no need for voice artists to worry about the replacement of AI voice. No matter how advanced the AI voice is, it can’t ever reach the level of naturalness of the human voice.

What are some limitations of AI voice?

Some limitations of AI voice include no emotion and personalized voice as its voice is copied from millions of sources, and the sentiment is that AI can never duplicate humans. Besides, AI voice can stand more chances of mispronouncing.
