Robotic Text to Speech vs. Natural Sounding Text to Speech: All You Need to Know 

Have you ever pondered the secret behind authentic, human-like text to speech voices?

If your answer is in the affirmative, well, this post is for you!

As we advance into a voice-first world, TTS technology is growing more and more sophisticated and enabling various capabilities that were previously considered unimaginable. What's even more intriguing is that quality isn't something that gets sacrificed when it comes to text to speech voices. Instead, it's one of the things you gain, making TTS voices so real that often you can't tell the difference between robotic text to speech and natural-sounding text to speech.

There are several reasons why AI-powered natural TTS voices shines over robotic TTS something we're going to explore at length in this post. We'll also cover the differences between robotic text to speech and natural-sounding text to speech and how you can create both with ease.

What is a Robotic Voice Generator?

The voice synthesis and voice recognition industry are constantly evolving, with several new technologies disrupting the space. The last few years have seen a rapid rise in robotic text to speech taking over various day-to-day tasks of businesses.

Robotic voice generators are based on artificial intelligence (AI) that not only understands human speech and recognizes emotions but also keeps conversations going by generating custom voices through a speech voice modulation technique that copies the nuances of human speech in real-time without making it sound too robotic. 

However, when communicating with a robot voice generator or voice-based chatbot, the key challenge you encounter is being able to distinguish a robot's voice from a human's. Good AI voice generators play an important role in achieving this level of voice quality. 

Robotic vs. Natural Voices: What's the Difference?

So, what are robotic and natural TTS voices, and how do they differ? Let's find out.

Robotic TTS Voices

Robotic text to speech tools work primarily by synthesizing digital text. Such systems turn digital text into audio or speech output using AI-driven algorithms as input. 

These systems are, therefore, in most cases, not able to produce the same kind of pauses, pitches, pronunciations, and tones as real or AI voices, leading to speech or audio that sounds like a computer-generated voice.

Natural TTS Voices

A natural AI voice generator, on the contrary, is better equipped to convert any digital text into different voices that are more natural-sounding speech and provide a more authentic listening experience.

The key differences between the two are listed below:

Pauses at the right places 

One of the ways natural voices in text to speech differ from robotic ones is in the use of pauses. Unlike AI-based robots, humans naturally pause for actions such as inhaling, exhaling, swallowing, and starting over again. These pauses help create rhythmic, natural-sounding variations in speech.

Robotic voice generators, on the other hand, do not focus on this nuance, leading to mechanical-sounding male or female voices. 

Inconsistencies 

Robotic text to speech software are designed to pronounce every single word the same way, leading to a monotonous-sounding speech.

However, when humans talk, we naturally alter or tweak the way we say words, even the words that are exactly the same. Therefore, with natural text to speech generators, the result is more realistic-sounding voices due to the use of varying tones and the addition of inflections and different emphases.

Intonation 

When humans speak, we naturally emphasize specific words through intonations, something that a robotic TTS voice tool fails to replicate.

However, today's AI-based TTS software is programmed to use intonations and can analyze tons of speech, voices, and other languages at once.

Which is the Better Option: Robotic Voices or Natural Text to Speech Voices?

To decide which is the better tool for your specific needs, let's compare the most important parameters of the two.

Quality of Voice  

The key difference between natural industry-leading TTS voices or generators and robotic voice generators is the quality of the voices produced from the text.

While the former is capable of reading text aloud in a distinctive way that sounds completely natural, robotic-sounding TTS are unable to produce the same effect, making the voice sound robotic or mechanic.

Replication of the Text's Tone, Accent, Pitch, and Volume 

Since natural-sounding audio software can make sense of the context of the text it is reading, it is more capable of replicating the text's intended pitch, pronunciation, tone, volume, accent, etc., rather than just reading text aloud in a plain, emotionless voice.

Features

Apart from producing high-quality voices that sound more natural compared to robotic voices in text to speech software, natural TTS generators also offer a range of other features. These include the ability to adjust the reading speed and volume and synthesize text in multiple languages of human voices, among others.

In terms of real-life use cases, both natural text to speech generators and robotic TTS have a few common uses, such as offering readers with dyslexia and other learning and visual disabilities the option to listen to the text instead of reading it themselves.

However, both the real-time synthesis of written text and the quality of audio files produced as the output in a natural TTS generator are much better than those produced by a robotic TTS tool.

Advantages of Natural Sounding Text to Speech Voices 

Using realistic text to speech technology offers several benefits, enhancing user experience and promoting accessibility and inclusivity. Let's explore these benefits in detail:

Enhanced User Experience

Natural-sounding TTS creates a more engaging and emotionally resonant user experience. By accurately conveying the intended emotions and tone, it can evoke the desired reactions and strengthen the connection between the content and the audience. It adds a human-like touch to the audio, enhancing the user experience.

Natural-sounding text to speech also enhances the clarity and intelligibility of the spoken content, making it easier for users to understand and retain information. Appropriate intonation, pacing, and emphasis help to convey the meaning effectively, ensuring the message is communicated accurately and efficiently.

Accessibility and Inclusivity

Text to speech is also vital in making digital content accessible to individuals with visual impairments. TTS enables visually impaired individuals to consume written information by converting text into speech without relying solely on visual cues. It allows them to access a wide range of content, including books, articles, websites, and more, promoting inclusivity and equal access to information.

That said, the tool also provides a more comfortable and enjoyable listening experience. It eliminates the need to read long blocks of text, particularly for those who find reading tedious or have difficulty reading for various reasons. By simply listening to the content, users can multitask, engage with the information hands-free, and absorb the content more relaxedly.
