ByJael Lawler

Text-to-speech (TTS) apps provide a convenient way for people to have digital text read aloud to them. These apps use speech synthesis technology to convert written text from ebooks, articles, documents and other digital sources into natural sounding speech. TTS apps allow users to listen to books, articles, or other text materials while multitasking or on the go when reading is not possible.

One of the main benefits of TTS apps is their accessibility for people who have visual impairments, learning disabilities, or other conditions that make reading on screens difficult. TTS technology helps remove barriers to information for these groups. It allows them to enjoy books and other materials by simply listening. For people without disabilities, TTS apps also provide an easy way to turn reading materials into an audio experience, useful while driving, exercising, cooking, or engaged in other activities.

TTS apps provide functionality similar to audiobooks in that they read text aloud. However, audiobooks are prerecorded by human narrators while TTS apps synthesize speech automatically. TTS gives users more flexibility and access to customize their experience, like adjusting playback speed or choosing different voice options. Audiobooks provide a more natural listening experience but are more limited in scope. Overall, TTS apps make digital text more accessible as an audio experience for a wide range of users.

Brief History

The origins of text-to-speech technology date back to the late 18th century, when inventors first attempted to build machines that could produce human speech. In 1791, an Austrian inventor named Wolfgang von Kempelen created a machine called the “Speaking Machine” that used bellows, reeds, and other parts to mechanically replicate the human vocal tract and produce some speech sounds (Speech synthesis, Wikipedia, 2022).

In the 1930s, Bell Labs developed the VOCODER, a device that analyzed and synthesized speech. This marked an important early milestone in digital speech synthesis (A Short History Of Text-To-Speech, Speechify, 2022).

The first fully computer-based speech synthesis systems were developed in the 1950s and 60s. In 1968, Japanese researchers led by Noriko Umeda created the first general English text-to-speech system at Japan’s Electrotechnical Laboratory (The History and Improvements of Text-To-Speech Technology, Hossain, 2018).

Though pioneering systems emerged in the mid 20th century, text-to-speech technology only started to become more mainstream and accessible to the public in the 1990s with the rise of personal computers. As computing power increased exponentially according to Moore’s Law, text-to-speech systems improved in naturalness and accuracy.

Today, text-to-speech is ubiquitous across smartphones, e-readers, in-car systems, and a range of everyday technologies. The quality of synthetic voices continues to improve, aided by deep learning and AI techniques.

How Text-to-Speech Apps Work

Text-to-speech (TTS) apps convert written text into synthesized speech using advanced technology. The apps break down the text into individual words and sounds through a process called text analysis or natural language processing. This involves identifying words, punctuation, numbers, abbreviations, acronyms and converting them into phonetic transcripts that represent how each word should be pronounced.

The phonetic transcripts are then fed into a speech synthesizer which generates artificial human-sounding voices. The synthesizer combines the phonetic sounds with pitch, tone, pauses, emphasis and other elements to mimic natural speech. Some advanced TTS apps utilize deep learning and neural networks to produce increasingly human-like voices and more natural cadence.

In summary, TTS apps use the following steps:

  1. Analyze the text using NLP to understand words, punctuation, numbers, etc.
  2. Convert the text into phonetic transcripts indicating pronunciation.
  3. Feed transcripts into a speech synthesizer to generate the speech.
  4. Output clear, natural sounding speech reading the text aloud.

By leveraging advanced artificial intelligence, text-to-speech apps can read digital text aloud while conveying the meaning with remarkable accuracy. Sources: Basic Text to Speech, Explained

Top Text-to-Speech Apps

There are many excellent text-to-speech apps available across various platforms. Some of the most popular generic reading apps include:

There are also specialized apps tailored for reading long-form content like books:

These apps allow you to load content from various sources and have it read aloud using high-quality text-to-speech voices. They provide customizable speed, voices, exporting, and other useful features.

Pros of Text-to-Speech Apps

Text-to-speech apps offer many benefits and advantages to users. Some of the main pros include:

Accessibility – Text-to-speech allows people with visual impairments, dyslexia, or other reading disabilities to listen to written content. This increases accessibility and inclusion for people who struggle with reading text on screens or in print (Text-to-Speech (TTS)).

Learning Assistance – Listening to text read aloud can improve comprehension, vocabulary acquisition, and retention for students and lifelong learners. Hearing the words aids in processing and absorbing information (Text-to-speech for students: enhancing the learning process).

Convenience and Portability – Text-to-speech apps allow users to listen to books, articles, or other text while multitasking or on-the-go. This provides a hands-free, convenient way to absorb content.

Voice Customization – Many text-to-speech apps allow users to select different voices, accents, and speech speeds to optimize for their personal preference.

Text Scanning and OCR – Some apps can scan and read text from physical books or documents using a device camera and optical character recognition (OCR) technology.

Cons of Text-to-Speech Apps

While text-to-speech apps provide many benefits, there are some limitations to be aware of. One of the biggest drawbacks is the robotic and unnatural sound of the computer-generated voices. Even as the technology improves, the voices can still sound choppy, monotonous, and lack inflection compared to human narration.

Text-to-speech apps also struggle with pronouncing unfamiliar words and names correctly. They may mispronounce words that are not in their pronunciation dictionary. This can disrupt the flow and comprehension.

Most text-to-speech apps require an internet connection to function. Without connectivity, the apps will not be able to convert text to speech. This makes text-to-speech unusable in areas with no internet access.(1)

There are ways to download audio versions of content for offline use. However, the inability to convert new text to speech on the fly limits the flexibility of these apps.

While the technology is rapidly advancing, text-to-speech still cannot perfectly mimic human expression and inflection. For leisure reading, many people still prefer human narration for a more enjoyable experience. But for productivity, accessibility, and convenience, text-to-speech apps provide useful functionality.

Best Practices for Use

Here are some tips for getting the most out of text-to-speech apps:

  • Take time to browse the different voice options. Choose a voice that is pleasant and natural sounding to you. Many apps allow you to download additional voices.
  • Start at a slow speaking rate so you can understand the words clearly. You can pick up the pace as you get used to the voice.
  • Use the feature to highlight text as it is read. This helps you follow along.
  • Add proper punctuation like commas and periods. This allows the app to pause briefly at the right spots.
  • Break up large blocks of text into smaller paragraphs. This makes it easier for the app to apply the proper intonation.
  • Adjust the pitch and speaking rate to optimize clarity. Some voices sound better at higher or lower pitches.
