Have you ever imagined generating a voice from the text? It’s a strange concept, right? However, all of our voices are actually a combination of different sounds and words. When you speak, the sounds combine to create words, which combined together form sentences, which then combine to form phrases or sentences that create a story. So, in essence, you generate voice from text every time you speak!

Whether it’s talking to our children or our friends, voice is a way for people to convey ideas, emotions, and feelings to another person. Being that voice is an important way of communicating, it makes sense that someone would be interested in generating voice from the text. In this post, I’ll explore the science behind realistic text to speech (TTS) apps and their use cases.

How Voiceover Apps Generate Voice From Text

Questions concept illustration

Voice generation from text isn’t a new concept. In fact, it’s been around since the days of radio. However, the technology for text-to-voice conversion has improved significantly over the past few decades.

When generating voice from text, you’re actually using an algorithm to process text and then convert it into speech. The algorithm analyzes each word in the text and breaks it up into basic units.

For example, it breaks sentences into words, then words into phonemes, and finally, phonemes into sounds. The algorithm then takes these sounds and creates words and phrases from them. This may sound odd, but it’s how speech is produced.

So, in essence, voice generator apps like Speechelo takes text, break it up into its basic units, analyze them, and then create a speech that communicates the thought or message of the original text.

While you’ll likely never see the algorithm that creates voice from text, it’s important to understand how it works. That way, you’ll know what to look for when analyzing voiceover apps.

Our app, Speechelo, is the best way to convert your text into realistic speech. The below demo video shows you how easy it is to use our app to create high-quality voiceover files.

Why AI Voice Generator Apps Are So Popular


Voice generation from text is used by people all over the world as an easy way to convert text into speech. People use voiceover apps like Speechelo for a variety of purposes. A few ot them are as below:

1. Voicemail Greetings

Voicemail greetings are also commonly referred to as IVR greetings. An IVR greeting is an automated message that plays when a person calls a phone number. These messages help customers complete simple tasks, such as providing their account number or choosing a language.

Voicemail greetings are most often used by businesses. For example, when you log into your online banking, you might hear an automated message that asks, “Press 1 for balance” or “Press 2 for transfer.”

Voicemail greetings are useful in everyday scenarios. These messages allow businesses to take care of thousands of customers at the same time.

2. Podcasting

Podcasting is a form of audio broadcasting. People use podcasts as an easy way to listen to audio. Podcasting provides listeners with educational, motivational, entertainment, or informational content. You can generate voice from text to create a podcast.

For example, you can convert all of your blog posts into podcasts. Or, you can just convert a few posts to create an audio version of your most popular posts.

3. Audiobooks

Audiobooks are similar to podcasts. However, audiobooks are longer than podcasts. Most audiobooks are between 30 minutes to 2 hours long. Audiobooks provide a great reading experience.

Audiobooks are popular because many people prefer listening to audio to reading text. To create audiobooks, you’ll first need to convert the text to audio files. And, like podcasts, you can create audiobooks in mp3 formats using text-to-speech apps like Speechelo to generate voice from text.

4. Commercials

Commercials have long been used for advertising products and services. In fact, the commercial industry is worth billions of dollars. Businesses use commercials to generate sales, promote their brand, and inform customers about their products.

Companies often hire voice actors to create commercial messages. So, rather than paying for expensive VO artists, businesses can use voice generation applications to generate voice from text to create professional commercials at a fraction of the cost.

5. Radio

Voice generation apps are especially helpful for radio stations that broadcast around the clock. Radio stations can use text-to-speech apps to generate voice from text for a variety of purposes. 

For example, radio stations use voiceover apps to play news, weather, traffic, and other announcements. 

So, rather than hiring expensive actors, radio stations can produce their own advertisements.

6. Video Voiceover

Voiceover (or VO) is an important part of a video. It’s essential because it adds clarity, emotion, and life to a video. It typically contains narration, commentary, and dialogue. VO is used in all types of videos, including explainer videos, promotional videos, marketing videos, and more.

Although voiceover is an important aspect of videos, it can be difficult to produce. It’s time-consuming and expensive to create high-quality voiceovers. So, many businesses hire professional VO artists.

However, a VO artist can cost thousands of dollars. It’s not feasible for many businesses to hire professional VO artists. So, they turn to voice generation apps like Speechelo to generate voice from text to create high-quality human sounding voiceovers.

So, you see, voice generation apps are pretty useful for a variety of purposes and can help people save time, money, and effort. It’s no wonder that voice generation apps have become so popular.
