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 are Robotic Text to Speech Generators?
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
Natural text to speech voice generators, on the contrary, are tools that are 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.
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.
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.
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.
How Can You Generate Robotic Text to Speech?
Here are some of the top software tools you can use to generate robotic voice:
MagicMic is an all-in-one robotic voice generator that allows you to do everything from changing your voice to adding high-quality sound effects to the voices produced.
The software offers varied high-quality robotic effects and allows you to import local files from your computer storage as well.
A professional robotic AI voice generator, Voicemod allows you to generate robotic sounds with relative ease. Further, you can use the software to add robotic sound effects directly to apps or games without much hassle.
Voxal is another powerful robotic voice generator with a wide sound library and high compatibility. You can use the platform to edit the distortion and amplification in your voice by simply changing the settings.
Why are Natural-Sounding Text to Speech Tools Better?
Natural text to speech tools have multiple applications across businesses as they seamlessly create natural-sounding voices using artificial intelligence technology.
Here are some of the top tools you can use to generate natural text to speech:
Murf is among the best natural-sounding TTS tools available that allow you to create everything from text to speech outputs, voiceovers, and transcriptions.
An AI-based tool, Murf is a great product to use for creators, educators, podcasters, and business professionals. The main highlight of Murf is that it provides voices trained by professional voice-over artists and also checks the voices across multiple parameters.
Lovo is another modern text to speech tool in the AI voice generator category that is ideal for people who don't want to go with 'recording your own voice' option. It can be used in eLearning, audio advertisements, audiobooks, and more.
An AI TTS generator and voice maker, Speechelo can easily create human-sounding speech from any text. Apart from this, the platform has a range of features, such as adding intonation to the voice and allowing you to choose the pitch and tone in which the text is spoken.
WellSaid Labs is yet another leading AI text to speech voice generator that helps you achieve human parity in AI voices. It is an excellent platform for product developers, creators, and brands who wish to highlight their digital experiences with a wide array of voice styles, tones, pitches, accents, and languages.
Speechify is a powerful natural text to speech generator that makes it much simpler to access information. Its TTS technology allows you to listen to any text out loud, including articles, PDFs, documents, and emails.
When it comes to creating voiceovers, there's always a risk of either ending up with bad-quality, robotic voices or going through the hassle of hiring a professional voice artist, renting a recording studio, and so much more.
The best way to navigate this is by using high-quality realistic text to speech converters like Murf Studio and benefiting from 100 percent human-sounding for a variety of use cases spanning educational videos, promotional videos, explainer videos, podcasts, and more.
