It’s your job to prepare the lecture for a company training on Monday, and you’re in a full-blown panic. While you have no problem making the presentation deck — seriously, you can do it with your eyes closed — you’re not entirely confident about how your voice sounds and would prefer it if someone else could narrate in your stead.

Unfortunately, there’s no one else. You’re responsible for the whole thing, from preparing the deck to narrating the presentation script. Thus, the panic attack. What should you do?

Here’s the solution. Use a text-to-speech generator (also known as a TTS generator), specifically one powered by artificial intelligence. Whenever you need a voice to narrate or read scripts, articles, lectures, learning materials for courses, or presentation, you can use an AI text-to-speech converter instead of using your own or the voice of a friend or a professional voiceover talent.

What Is an AI Text-to-Speech or Text-to-Voice Generator?

A text-to-speech generator is a voice synthesizing software or application that converts written words (i.e., text) into words spoken (i.e., speech) by a synthetic voice or artificial voice. Yes, it is as straightforward as its name suggests.

How about artificial intelligence text-to-speech programs? They are just like traditional text-to-speech software, except they use AI voices to synthesize speech. Thus, AI text-to-speech applications produce realistic text-to-speech outputs, producing synthetic voices that seem remarkably human-like in vocal qualities such as pitch, rate, vocal quality, and even in their use of fillers.

The Features and Benefits of AI Text-to-Speech Generators

AI text-to-speech applications are more advanced than your run-of-the-mill TTS tool because they use artificial intelligence, specifically machine learning, to generate synthetic voices.

Natural and Realistic AI Voices

Traditional TTS converters used pre-recorded speech units joined together to synthesize speech. The result is a strange, robotic-sounding voice.

Meanwhile, TTS converters that use AI voice synthesizers have been trained in databases containing tens of thousands of different human voices. During this learning phase, they assimilate the voices they “hear” and find patterns in the way humans speak, particularly in the non-lexical components of human speech or the elements of speech that do not pertain to words and their definitions.

Through rigorous training, an AI voiceover generator or speech synthesizer not only learns to say the words and dialogues it has assimilated from its learning materials. Inference engines enable them to apply learned patterns to fresh content. It is this capability to infer and analyze new information that makes them seem like thinking or intelligent beings.

Because of their advanced programming, learning mechanisms, and inference engines, AI speech synthesizers can generate voices that sound so human-like that ordinary persons (i.e., non-linguists and voice talents) may be unable to distinguish them from actual human voices. There are even AI voice generators that are so advanced they produce speech that successfully captures and conveys the intended emotions of the text.’s newest ultra-realistic AI Voices belong to this category. These ultra-realistic voices masterfully utilize pitch, rhythm, rate, volume, intonation, and pronunciation/enunciation to deliver meaningful information and convey the speaker’s emotion.

A Wide Selection of AI Voices and Styles

AI speech synthesizers offer multiple AI voices, with many supporting style variations. There are upbeat and solemn voices, professional and friendly voices, booming and soft voices, and all sorts of variations in between. Some voices sound like a newscaster delivering the afternoon news, a customer service representative providing customer support, a narrator giving commentary to a documentary, and a cheerful host inciting excitement at a party.’s online text-to-speech generator has a database of 907 AI voices, and our collection of AI voices is still growing.

Granular Control Over Speech Attributes

Humans convey meaning through the words we speak and how we say them so it is important that a speech generator can produce authentic vocal dynamics.

To this end, superior AI text-to-speech platforms do not only offer ready-made voice styles. They also provide granular control over how the AI voice delivers the speech so it can approximate human speech even more. allows you to emphasize specific words and even entire sentences. This lets you alter your rhythm and create more dynamic speeches. Additionally, you can modify the rate, pitch, and volume of a particular AI voice to further customize your speech output.

Multiple Voices in One Audio File

TTS conversion is used not only to read articles or narrations aloud. It is also used to create podcasts, advertising or promotional materials, and audiobooks. Advanced AI text-to-speech applications allow content creators to use multiple AI voices in a single file to create dialogues or other types of conversational outputs.’s online text-to-speech synthesizer has this capability. You can assign distinct AI speakers to different paragraphs. With, you can create a full panel discussion or an entire program with active audience participation based on a single script. then allows you to download the individual paragraphs (each with a distinct AI speaker, if needed) as separate audio files or download the entire “conversation” as a single audio file.

Availability of AI Voices in Multiple Languages

There are AI-powered TTS tools that can convert text to speech in non-English languages.’s text-to-speech online generator has AI voices in 142 languages and accents.

The wide range of languages available makes AI-driven TTS platforms especially useful to developers and creators of learning courses. If you have a training program you want to take global, you can do so easily with the help of a multi-language-capable TTS platform like

While you can continue to offer your course in English, localizing it will give your material a much broader reach. Localization will also make it more relatable to (and more effective for) your target audience.

Voice Cloning Ability

AI also makes it possible to create a digital representation of your voice, also known as a voice clone. This enables you to develop personally branded video presentations, podcasts, and narrations.

The best part is that you don’t need to spend hours recording your narrations, commentaries, and dialogues in a studio. Feed your script to your AI text to voice generator and, in minutes, get an audio recording of someone that sounds just like you. is one of the best AI voice generator, text-to-speech platforms around because of its voice cloning abilities. It lets you enjoy the ease and convenience of using an AI text-to-speech tool to narrate all your speaking parts while maintaining a consistent voice across all your materials. 


There are also AI TTS converters that you can integrate with other tools for creative use cases.

For instance, you can use a plugin on your WordPress website to make your blog “listenable” and “podcastable” instead of simply readable and shareable.

You can also integrate the text-to-speech engine , your TTS devices and applications to extend their functions and gain granular control over your current text-to-speech conversion options with help of our Text-to-Speech API. Through the TTS application programming interface (API), you can continue using your favorite Google, IBM, and Amazon voices but enhance your experience with’s advanced back-end functions.

How to Use an Online AI Text-to-Speech Converter

Using an AI text-to-speech converter is easy.

Typically, all you need to do is load your TTS converter on your browser window, type your text into the designated text-input window, click “Convert,” and the program will generate a synthetic voice speech based on your content.
