What is speech synthesis?

Speech synthesis, or text-to-speech, is a category of software or hardware that converts text to artificial speech. A text-to-speech system is one that reads text aloud through the computer's sound card or other speech synthesis device. Text that is selected for reading is analyzed by the software, restructured to a phonetic system, and read aloud. The computer looks at each word, calculates its pronunciation then says the word in its context (Cavanaugh, 2003).

How can speech synthesis help your students?

Speech synthesis has a wide range of components that can aid in the reading process. It assists in word decoding for improved reading comprehension (Montali & Lewandowski, 1996). The software gives voice to difficult words with which students struggle by reading either scanned-in documents or imported files (such as eBooks). In word processing, it will read back students' typed text for them to hear what they have written and then make revisions. The software provides a range in options for student control such as tone, pitch, speed of speech, and even gender of speaker. Highlighting features allow the student to highlight a word or passage as it is being read.

Who can benefit from speech synthesis?

According to O'Neill (1999), there are a wide range of users who may benefit from this software, including:

  • Students with a reading, learning, and/or attention disorder
  • Students who are struggling with reading
  • Students who speak English as a second language
  • Students with low vision or certain mobility problems

ReadPlease 2003
This free software can be used as a simple word processor that reads what is typed.

ReadPlease ReadingBar
ReadingBar (a toolbar for Internet Explorer) allows users to do much more than they were able to before: have web pages read aloud, create MP3 sound files, magnify web pages, make text-only versions of any web page, dictionary look-up, and even translate web pages to and from other languages. ReadingBar is not limited to reading and recording web pages - it is just as good at reading and recording text you see on your screen from any application. ReadingBar is often used to proofread documents and even to learn other languages.

Max's Sandbox
In MaxWrite (the Word interface), students type and then hear "Petey" the parrot read their words. In addition, it is easy to add the student's voice to the document (if you have a microphone for your computer). It is a powerful tool for documenting student writing and reading and could even be used in creating a portfolio of student language skills. In addition, MaxWrite has more than 300 clip art images for students to use, or you can easily have students access your own collection of images (scans, digital photos, or clip art). Student work can be printed to the printer you designate and saved to the folder you determine (even network folders).
