Have You Ever Wondered How Text-To-Speech Voices Are Made?

The Verge has a cool video about how text-to-speech videos are produced. Given that so many assistive technologies rely on text-to-speech voices it is interesting to learn how they have been improved over the years to sound more realistic. One of the most well known applications of text-to-speech is Apple's Siri. The video features Nuance the makers of Dragon.

Prizmo 2.0 for iOS Released With Cool New Features

Prizmo 2.0 for iOS was just released in the App Store. Prizmo now works on the iPad as well as the iPhone and iPod Touch. The update includes many exciting new features. The original version of Prizmo included optical character recognition (OCR) but did not include the ability to scan documents to a PDF or text file. The PDF files are not just images but include searchable text. Prizmo 2.0 also allows users to export the documents to other apps.

To create a new document in Prizmo you can simply take a picture of multiple pages. Prizmo will automatically detect the edges of the page. In version 2.0 you no longer have to crop documents manually. Once you have captured all of the pages you can recognize the text of the document which is surprisingly fast and accurate. If the Prizmo does make a mistake you can edit the OCR zones or manually edit the text. After the text has been recognized you can email or export the document as a PDF or text document or read the text using built-in text-to-speech. The text is highlighted as it is read aloud which can be helpful for people with dyslexia  Unfortunately you can only read one page of the document at a time using the built-in text-to-speech. In addition, it is important to note that each text-to-speech voice costs $2.99.

Prizmo is still a great tool for quickly reading printed documents using text-to-speech and now is one of the best PDF scanning apps. Most PDF scanning apps such as Scanner Pro only make an image PDF with no text but Prizmo creates PDFs with searchable text.

Prizmo 2.0 includes a new feature to help blind and visually impaired users line-up a document. Because it would be virtually impossible for the blind to take a well aligned picture of a document with out assistance Prizmo voices directions through VoiceOver. If a user has VoiceOver turned on it will tell a blind or visually impaired user which direction to move their device in order to get the perfect shot.

Prizmo is on sale for $5.99 in the App Store. Click read more below to view screenshots of Prizmo 2.0.
