What is Text-to-Speech Technology

TTS, or Text-to-Speech, is an assistive technology that reads digital text using AI algorithms. It was initially developed in 1968 by Norika Umeda to help visually impaired and disabled people. Fast forward to today, the technology has become advanced to the extent that these tools now understand the text's tone, pitch, and energy. Therefore, the sound produced is even better than non-native speakers.

Who Uses TTS?

  • People with Learning Disabilities:
  • People with impairments like dyslexia, ADHD, and other disorders use TTS tools to consume content daily. It is also an excellent substitute for such people in learning the literature from research papers and academic reports.

  • People with Literary Issues:
  • Trying to learn a new language and reading an entire document in this language can be frustrating. This is where the text-to-speech software may come in handy. These tools read extensive content in your second language, making it easily apprehendible.

  • Casual Content Consumption:
  • Moreover, people like to enjoy content casually. But reading it may not be their preference. But it is made easy with text-to-speech tools. So, whether you are enjoying an e-book while working or catching up on the news while traveling, TTS apps have got you covered.

  • Content Owner's:
  • TTS tools can also be an excellent help for publishers. It improves the accessibility of their content.

How Text to Speech Works

TexttoSpeech consists of two components: front-end and back-end. The front end is what the users interact with, while AI primarily handles the back end. To understand the text-to-speech working mechanism, these two components matter. So, let us know more about them.

1. Front End

The front end is commonly referred to as a text-to-speech interface. All you need to do is enter the text, set preferences (language, voice, tone, etc.) and hit the convert button. It uses the API and plugins to automate the entire conversion process. In minutes, you will have the technology to read the text out loud.

2. Back End

The back end is where the real thing happens. The entire system is how the AI does its job in the background using the acoustic model, which usually deals with linguistic and latent features. Here is how it works.

  • Pre-Processor: The text on the screen is pre-processed and broken down into words. This helped the system understand the pitch and tone of the text.
  • Encoder: Next, the words enter the encoder input, where the linguistic features process the text. They use part-of-speech tags, pronunciation tags, and syntactic structures to train the system.
  • Decoder: Then, it enters the decoder. Here, the text is processed using latent algorithms and converted into acoustic features.
  • Vocoder: The vocoder converts the acoustics into waveform and generates the speech.

Benefits of Text-to-Speech Tools

Text-to-speech technology was originally developed to aid people with learning disabilities. However, the advancement of neural networks and artificial intelligence in TTS resulted in its excessive use. Here are some ways it benefits individuals and brands on a day-to-day basis.

  • Better Reach:
  • TTS tools amplify your content and repurpose it. Most brands utilize text2speeh models to convert their articles into podcasts, audio scriptures, voiceovers, and social media audio presentations.

  • Time-Saving:
  • With text-to-speech tools, there is no need to hire an interpreter or voiceover artists is unnecessary. Everything is done by software and artificial intelligence, saving time and streamlining the process.

  • Accessible and Cost-Effective:
  • Today, numerous TTS tools are managed by AI, offering competitive pricing. Therefore, it eliminates the need to hire manual speakers to do the job, which reduces the cost.

  • Include Disabled Audience:
  • Typically, the text-to-speech models are most helpful to people with visual impairment, like dyslexia, ADHD, and more. This way, they can perform routine tasks.

  • Prevent Reading Fatigue:
  • Prolonged reading can cause eye strain and reading fatigue. This is where text-to-speech tools come in handy. You can also connect them with Bluetooth and a soundbar to multi-task and make reading a shared experience.

Types of Text-to-Speech Tools

Text-to-speech tools come in different types, depending on the medium you are using. So, let us discuss each in detail.

1. Text-to-Speech Software Programs

Typically, software using the TTS export model is designed for reading and writing literacy. You may have come across them as speech synthesis or speech generators. These tools translate lengthy documents into synthesized audio. It helps them better engage the audience and make the content accessible.

When paired with AI, these technologies produce a natural-sounding human voice with a modified speaking style. Advanced TTS software also uses neural networks to make the sound inclusive of pitch, emotion, and natural pauses.
