Given a written text as input, a machine called speech synthesizer, which can be a <strong>software<\/strong> or a <strong>hardware<\/strong>, turns written words into <strong>artificial voice<\/strong>.<\/p>\n<p>To make the concept of <span style=\"color: #ff9900;\"><strong>speech synthesis<\/strong><\/span> more familiar, just think of how Siri or Alexa interact with us. These <strong>voice assistants<\/strong> have a dual function: first they translate whatever request the user orally puts to them into written text, then they vocally reproduce the <strong>desired response<\/strong> by reading content carefully selected on the <strong>web<\/strong>.<\/p>\n<p>Not only does this new technology bring numerous <strong>benefits<\/strong> from an <strong>economic <\/strong>and<strong> business<\/strong> <strong>point of view<\/strong>, but it is also vital for the learning and <strong>accessibility<\/strong> of written content to an increasingly wide audience, proving to be an effective tool especially for people with <strong>disabilities<\/strong> and those with <strong>learning disorders<\/strong>.<\/p>\n<p>For these very reasons, more and more companies are beginning to take <strong>advantage<\/strong> of this real technological revolution. We at <strong>Creative Words<\/strong> have also decided to adopt <span style=\"color: #ff9900;\"><strong>speech synthesis<\/strong><\/span> as an integral part of our communication, thus offering the possibility of accessing the content of <span style=\"text-decoration: underline;\"><span style=\"color: #ff9900; text-decoration: underline;\"><a style=\"color: #ff9900; text-decoration: underline;\" href=\"https:\/\/creative-words.com\/en\/blog\/\">our blog<\/a><\/span><\/span> also in <strong>audio format<\/strong>.<\/p>\n<p>Let us now see together how this new technology works and what its advantages are.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>What is a speech synthesizer used for and how does it work?<\/strong><\/h2>\n<p>A <strong>speech synthesizer<\/strong> is a tool based on the <strong>Text-to-Speech<\/strong> (TTS) technique that can read a written text, interpret it by encoding all of its characteristics, and transform it into <strong>audio content<\/strong>. With this type of system, <strong>files<\/strong> in .txt, .pdf, .html, and even text contained in .jpg photographs can be processed to produce an audio recording that reads the content of such documents.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\" wp-image-28391 alignright\" src=\"https:\/\/www.fancyfestival.com\/creative-words\/wp-content\/uploads\/2025\/05\/speech-synthesis-and-sld-speech-synthesizer-300x169.webp\" alt=\"speech synthesis and sld speech synthesizer\" width=\"416\" height=\"234\" \/>There are several types of speech synthesizers. The most common are those that allow you to simulate reading with a <strong>digital voice<\/strong> in a few minutes, simply by highlighting the text you want to hear. This is referred to as highlighted <span style=\"color: #ff9900;\"><strong>speech synthesis<\/strong><\/span> or the &#8220;<em>karaoke effect<\/em>.&#8221; However, there are also more sophisticated software programs that allow you to choose between different languages and voices, which are distinguished by <strong>gender<\/strong>, <strong>age<\/strong> and<strong> tone<\/strong>. It is thus possible to bring to life audio content with human-like voices and to achieve <strong>natural<\/strong> and <strong>realistic results<\/strong>.<\/p>\n<p>These software offer the possibility of customizing the voice output and refining its characteristics according to the user&#8217;s needs. These are the so-called <strong>SSML-based software<\/strong>, a particular type of software based on the <span style=\"color: #ff9900;\"><strong>speech synthesis<\/strong><\/span> markup language.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Speech synthesis and accessibility: applications and benefits<\/strong><\/h2>\n<p><span style=\"color: #ff9900;\"><strong>Speech synthesis<\/strong> <\/span>is an essential tool for people diagnosed with a <strong>Specific Learning Disorder (SLD)<\/strong> and is especially helpful for those with dyslexia. Dyslexia is a neurological disorder characterized by learning difficulties and problems in <strong>reading<\/strong> and <strong>comprehension<\/strong> of a written text that manifests itself through slow, poorly fluent reading with numerous inaccuracies.<\/p>\n<p><span style=\"color: #ff9900;\"><strong>Speech synthesis<\/strong><\/span> precisely addresses these difficulties: by transforming a text into audio, it provides a viable alternative to the classic reading process to which we have always been accustomed. This is known as &#8220;ear-reading\u201d, a kind of virtual <strong>multilingual<\/strong> reading that makes it possible to identify the parts of text that one wants to read, to change the speed of reading, to change the intonation, and to choose the voice that allows for <strong>better understanding<\/strong> by the user.<\/p>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-28393\" src=\"https:\/\/www.fancyfestival.com\/creative-words\/wp-content\/uploads\/2025\/05\/speech-synthesis-and-sld-accessibility-300x169.webp\" alt=\"speech synthesis and sld accessibility\" width=\"696\" height=\"392\" \/>There are several studies highlighting the benefits of using <strong>text-to-speech<\/strong> by people with <strong>SLD<\/strong>. Indeed, this technology facilitates <strong>text comprehension<\/strong> and is a reading aid, converting into a faithful helper in the process of decoding written text. In this way, those with reading disorders can achieve learning autonomy, that is, the ability to communicate without having to depend on a facilitator. Lack of autonomy in learning is many times a cause of disesteem and often ends up compromising educational success.<\/p>\n<p>&nbsp;<\/p>\n<h3><strong>Some compensatory tools<\/strong><\/h3>\n<p>Compensatory tools are products (both computer-based and non-computer-based) that support learning by compensating for various activities such as studying, reading, writing, and calculation.<br \/>\nIn addition to <span style=\"color: #ff9900;\"><strong>speech synthesis<\/strong><\/span>, other compensatory tools to facilitate the <strong>study<\/strong> and <strong>work<\/strong> of individuals with <strong>SLD<\/strong> are:<\/p>\n<ul>\n<li><strong>Video-writing programs<\/strong>: these are software that improve writing performance. They allow for adjustment of text size, colors and styles easily, and provide for the use of typefaces suitable for readers with dyslexia. They also feature spell checker, grammar checker and word predictor.<\/li>\n<li><strong>OCR &#8211; Optical Character Recognition<\/strong>: it can recognize the characters of a written paper text by scanning it. And it transforms it into an electronic format so that it can be edited with a text editor.<\/li>\n<li><strong>Speech recognition<\/strong>: it recognizes and transforms what is spoken to a microphone into electronic text.<\/li>\n<li><strong>PDF annotation programs<\/strong>: these allow you to view PDF files and annotate the text, highlight sections and keywords, so as to facilitate diagramming and summarizing.<\/li>\n<\/ul>\n<h3><\/h3>\n<h3><strong>Other compensatory tools<\/strong><\/h3>\n<ul>\n<li><strong>E-books and Audiobooks<\/strong>: eBooks are published in ePub format, an open and interoperable format that, unlike PDF, allows the reader to change many features of the text so as to improve readability according to personal preferences. There is also a particular eBook format, audio eBooks, which combine reading an eBook with the ability to follow a narrator&#8217;s voice over the text.<\/li>\n<li><strong>Technologies for mathematics<\/strong>: these include spreadsheets, talking calculators, graphing calculators, and programs to support calculating and solving expressions and equivalences.<\/li>\n<li><strong>Note programs<\/strong>: they allow the collection of notes in an archive. With note organizers, notes can be divided by category, topic and format. A specific note can be retrieved through a simple text search.<\/li>\n<li><strong>Map-making programs<\/strong>: these are graphical tools that allow the creation of diagrams, mind maps and concept maps that link salient information and logical connections.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>For more details on how to make your digital content more accessible, don\u2019t hesitate <span style=\"text-decoration: underline;\"><span style=\"color: #ff9900; text-decoration: underline;\"><a style=\"color: #ff9900; text-decoration: underline;\" href=\"https:\/\/creative-words.com\/en\/contacts\/\">to contact the Creative Words team<\/a><\/span><\/span>!
