What IsText-to-Speech?

Text-to-speech (TTS) is an assistive technology that makes use of a machine learning model in order to convert text into an AI voice that reads it out loud.

Also referred to as read-aloud technology or speech synthesis, this is a speech generator that facilitates communication when reading the text is inconvenient or not possible. TTS can read every type of text, from emails to web pages, and is available on most digital devices, including tablets, laptops, and mobile devices. 

How Does Text-to-Speech Work?

Text-to-speech technology involves making use of an AI-based engine that has NLP (natural language processing) capabilities. The program works by generating human-like voices, which make the text sound more fluent and less robotic. The NLP engine takes a block of text and divides it into words and sentences before processing each word to generate speech. TTS is functionally the opposite of automatic speech recognition (ASR).

In many cases, users have the option to speed up or slow down the reading. Many speech synthesis tools also highlight the words or phrases as they are read. This enables the user to hear and see the content at the same time. Another possible feature of TTS technology is OCR (optical character recognition), which allows the speech synthesis function to detect and read text from images. 

Why You Should Use Text-to-Speech

Depending on the use case, text-to-speech can prove to be highly beneficial. It enables applications to become more accessible, allowing users to consume information without the need to concentrate on a screen. Major benefits of using read-aloud technology include:

  • Cost-efficiency: With the help of cloud computing, implementing text-to-speech is quick, easy, and cost-efficient

  • Enhanced user experience: Speech synthesis software can reduce the user’s workload and allow for a more handy and customized experience

  • Convenience: By transforming digital content into multimedia, TTS makes it easy to multitask while listening to digital texts like emails, articles, and even SMS reminders

  • Accessibility: Read-aloud applications offer an alternative way of accessing information to those who have literacy challenges or visual disabilities

  • Increased brand reach: TTS tools provide a tailored approach to different audiences by offering features like custom voices and regional accents

  • IoT Integration: Combining speech synthesis with IoT (Internet of Things) enhances the user experience and allows for a more helpful interaction

  • Flexible development: TTS technology is one that you can scale as necessary while appending it on the cloud and on-site

  • Enhanced learning: Read-aloud software can facilitate e-learning by helping to improve motivation, comprehension, and vocabulary skills 

What Is Text-to-Speech Used for?

Text-to-speech is an innovative technology with numerous benefits. This makes it a versatile tool that can serve a variety of purposes. Many SMS platforms use TTS to convert text to speech, making them more accessible and boosting customer engagement. Other use cases of TTS software include:

Automotive Industry

Text-to-voice software can see plenty of use in navigation programs, where it can give turn-by-turn directions. Infotainment systems can also make use of speech synthesis to read information about the mechanics of the car. For example, TTS can inform the driver about changes in the fuel level or tire pressure. 

Customer Service

In customer service, read-aloud technology can help in addressing issues or responding to customer inquiries. Adopting text-to-speech software can guarantee that customers are getting high-quality service. The use of natural-sounding voices also offers a more human approach to AI chatbots and interactive support centers.


TTS presents a simple way to turn educational content into a more effective format that is also less costly to release in multiple languages. It can read PDFs and other training documents out loud in addition to providing instructions for a task or a project. Students with learning disabilities like dyslexia can also benefit from speech-synthesis tools.


TTS technology is an excellent tool for translating a piece of text from one language to another. For instance, it can help tourists find their way in foreign countries. The program would read content in their native language. It can also help people of different nationalities understand each other in international business meetings.


Having a software read a document aloud can be helpful when it comes to proofreading. It makes it easier to catch mistakes that may otherwise go unnoticed when you’re reading the text silently. This makes speech synthesis an ideal tool for writers, editors, and other professionals.
