What Are the Uses of Speech Synthesis?

The text-to-speech tool has come a long way since its early days in the 1950s. It is now used in various applications, from helping those with speech impairments to creating realistic-sounding computer-generated characters in movies, video games, podcasts, and audio blogs.

Here are some of the most common uses for text-to-speech today:

1. Assistive Technology for Those with Speech Impairments

One of the most important uses of TTS is to help those with speech impairments. Various assistive technologies, including text-to-speech (TTS) software, communication aids, and mobile apps, use speech synthesis to convert text into speech.

People with a wide range of speech impairments, including those with dysarthria (a motor speech disorder), mutism (an inability to speak), and aphasia (a language disorder), use audio tools. Nonverbal people with difficulty speaking due to temporary conditions, such as laryngitis, use TTS software.

It includes screen readers read aloud text from websites and other digital documents. Moreover, it includes navigational aids that help people with visual impairments get around.

2. Helping People with Speech Impairments Communicate

People with difficulty speaking due to a stroke or other condition can also benefit from speech synthesis. This can be a lifesaver for people who have trouble speaking but still want to be able to communicate with loved ones. Several apps and devices use this technology to help people communicate.

3. Navigation and Voice Commands—Enhancing GPS Navigation with Spoken Directions

Navigation systems and voice-activated assistants like Siri and Google Assistant are prime examples of TTS software. They convert text-based directions into speech, making it easier for drivers to stay focused on the road. The voice assistants offer voice commands for various tasks, such as sending a text message or setting a reminder. This technology benefits people unfamiliar with an area or who have trouble reading maps.

4. Educational Materials

Speech synthesizers are great to help in preparing educational materials, such as audiobooks, audio blogs and language-learning materials. Some visual learners or those who prefer to listen to material rather than read it. Now educational content creators can create materials for those with reading impairments, such as dyslexia.

After the pandemic, and so many educational programs sent online, you must give your students audio learning material to hear it out on the go. For some people, listening to material helps them focus, understand and memorize things better instead of just reading it.

5. Text-to-Speech for Language Learning

Another great use for text-to-speech is for language learning. Hearing the words spoken aloud can be a lot easier to learn how to pronounce them and remember their meaning. Several apps and software programs use text-to-speech to help people learn new languages.

6. Audio Books

Another widespread use for speech synthesis is in audiobooks. It allows people to listen to books instead of reading them. It can be great for commuters or anyone who wants to be able to multitask while they consume content. Audio storytelling has recently gained popularity, with many people now using it to engage audiences through podcasts, audiobooks, and other formats.

7. Accessibility Features in Electronic Devices

Many electronic devices, such as smartphones, tablets, and computers, now have built-in accessibility features that use speech synthesis. These features are helpful for people with visual impairments or other disabilities that make it difficult to use traditional interfaces. For example, Apple’s iPhone has a built-in screen reader called VoiceOver that uses TTS to speak the names of icons and other elements on the screen.

8. Entertainment Applications

Various entertainment applications, such as video games and movies, use speech synthesizers. In video games, they help create realistic-sounding character dialogue. In movies, adding special effects, such as when a character’s voice is artificially generated or altered. It allows developers to create unique voices for their characters without having to hire actors to provide the voices. It can save time and money and allow for more creative freedom.

These are just some of the many uses for speech synthesis today. As the technology continues to develop, we can expect to see even more innovative and exciting applications for this fascinating technology.

9. Making Videos More Engaging with Lip Sync

Lip sync is a speech synthesizer often used in videos and animations. It allows the audio to match the movement of the lips, making it appear as though the character is speaking the words. Hence, they are used for both educational and entertainment purposes.

How to Choose and Integrate Speech Synthesis?

With the increasing use of speech synthesizer systems, choosing and integrating the right system for a particular application is necessary. This can be difficult as many factors to consider, such as price, quality, performance, accuracy, portability, and platform support. This article will discuss some important factors to consider when choosing and integrating a speech synthesizer system.

• The quality of a speech synthesizer means its similarity to the human voice and its ability to be understood clearly. Speech synthesis systems were first developed to aid the blind by providing a means of communicating with the outside world. The first systems were based on rule-based methods and simple concatenative synthesis. Over time, however, the quality of text-to-audio tools has improved dramatically. They are now used in various applications, including text-to-speech systems for the visually impaired, voice response systems for telephone services, children’s toys, and computer game characters.
• Another important factor to consider is the accuracy of the synthetic speech. The accuracy of synthetic speech means its ability to pronounce words and phrases correctly. Many text-to-audio tools use rule-based methods to generate synthetic speech, resulting in errors if the rules are not correctly applied. To avoid these errors, choosing a system that uses high-quality algorithms and has been tuned for the specific application is important.
• The performance of a speech synthesis system is another important factor to consider. The performance of synthetic speech means its ability to generate synthetic speech in real-time. Many TTS use pre-recorded speech units concatenated together to create synthetic speech. This can result in delays if the units are not properly aligned or if the system does not have enough resources to generate the synthetic speech in real-time. To avoid these delays, choosing a system that uses high-quality algorithms and has been tuned for the specific application is essential.
• The portability of a speech synthesis system is another essential factor to consider. The portability of synthetic speech means its ability to run on different platforms and devices. Many text-to-audio tools are designed for specific platforms and devices, limiting their portability. To avoid these limitations, choosing a system designed for portability and tested on different platforms and devices is important.
• The price of a speech synthesis system is another essential factor to consider. The price of synthetic speech is often judged by its quality and accuracy. Many text-to-audio tools are costly, so choosing a system that offers high quality and accuracy at a reasonable price is important.
