Speechify is also popular for its robust customization options. For instance, users can change the audio’s language, reading speed, accent, etc according to their needs & requirements.

Why AI Voice Generator Apps like Speechify are Successful? – Top Reasons

AI voice generator and best text to speech apps like Speechify have gained significant success in the market. The apps offer top notch customization and functionalities to the users. However, there are several other reasons behind the success of such apps, which are as follows –

1. Empowering Disabled People

Cliff Weitzman, the founder of Speechify, is a dyslexic kid who developed the app to help people with the same disability. Speechify’s fundamental function is to convert textual data into audio voices with different customizations and help people read lengthy documents easily.

2. Improves Writer Productivity

Apps like Speechify have gained success among writers, proofreaders, editors, and content creators. Editors & writers often skip mistakes in the write ups and hearing the text again in another voice can help in review process. The process increases the productivity and work quality by helping writers identify mistakes.

3. Lower Pricing Plans

Most AI voice generation apps like Speechify work on freemium model and offer a basic plan at no cost to users. This has made easier for people to try & adapt to the technology. Free plan offers the basic text to speech features while the premium plans offers additional functionalities. It includes customization in accent, reading pace, multiple language support, and many more.

Speechify’s plan starts from $11.58 per month per user.

Must-have Features For an App like Speechify

1. Multi Language Support

A text to speech that has multiple language support can help users transcend countries & culture without any issue. For instance, a text in Spanish converted into an English language audio can help reach text to more locations & people, thus, lifting the language barrier. Apps like Speechify offer text to sound feature for over 30 languages.

2. Voice Diversification

The problem with most text to speech apps in the market currently is that most of them have a robotic, linear voice that doesn’t have any human touch. Further, every text has a tone of its own and should be conveyed in the same manner for effective communication. Thus, a text to speech app must have the voice diversification feature that reads the text in the required tone. For instance, you need different voices when reading a novel and another when reading a tutorial.

3. Robust UI/UX

Nobody wants to install a text to speech app with confusing interface and complexity. An ideal AI voice generator app has an easy to understand navigation and delivers maximum results in minimum steps. For example, apps like Speechify make sure that the registration & profile creation process is done in less than 5 steps. A complex UI eats a lot of user energy & attention, resulting in app removal.

4. Improve Speech Quality

It is time-consuming and costly to produce multiple audio versions of your content using standard methods. Rehiring voice actors, renting a studio, and hiring audio experts will be necessary each time you need to update material. All of that is altered when your TTS has a voice changer feature.

Using TTS with a voice changer allows you to alter your voiceover’s gender, language, accent, and other characteristics in addition to enhancing the voice quality of your amateur recordings to that of professional voiceovers.

5. Customization Feature

Advanced text to speech technology can be used to create AI voices that have better intonation, naturalness, comprehensibility, and intelligibility than human voices. A voice that isn’t personalised is just another voice. Because of this, excellent text-to-speech software should allow users to customize the project’s voiceover according to certain use cases. Apps like Speechify allow top notch customization and better options to users, and that’s why, are a hit in the market.

Some people might need a loud and lively voice, while others would need a low-pitched voice that conveys the ideal mix of authority, intelligence, and clarity.

6. Files Import/Export

The capacity to import and export files in numerous formats with ease is another crucial element of any user-friendly AI voice generator app like Speechify. Working with digital information requires importing and exporting files on a regular basis. Either text can be copied and pasted into an editor or text files in various formats can be imported into the TTS programme. The finished audio file should be able to be exported in a number of different formats at the same time.

Allowing users to sync and incorporate media files, like presentations, movies, and photos, into the finished voiceover would be an additional benefit. This would enable users to create the ideal voiceover content.

7. Collaboration

Team collaboration is a noteworthy functionality that every text-to-speech program should have. Different people must be able to access and edit audio & video files, work on the same piece of material at the same time, and share inputs.

Working together in real-time not only allows users to avoid wasting several hours, but it also expedites projects and gets us over difficult obstacles more rapidly.

8. Natural Sounding Voice

Human-parity voices are the main feature that sets apart any text-to-speech software. The expressiveness, irregularity, and capacity to deliver the same sentences in radically various ways depending on the situation are what define human voices.

High-quality AI voices that can mimic the likeness, style, organic prosody, and individuality of human speech should be provided by text-to-speech software. The AI voice should be able to adjust its tone and emotion, as well as pause and breathe when necessary, thanks to contextual awareness. It should be simple for users to personalize their voiceover experience with a wide variety of options available for both male and female voices.
