ClaroSpeak is a quality app for proofreading text through listening, helping with reading and literacy development, and creating audio files from any text. PRODUCT FEATURES • Text-to-Speech - Type into ClaroSpeak and have the text read back to you.

The voice can be made to speak faster or slower. The voices are installed within ClaroSpeak, so they work when not online and do not use up any data allowance. Additional Nuance & Acapela voices in 30+ languages and even more accents are available through in-app purchase in ClaroSpeak. • Capture text from photo This feature lets you select a photo from your library or take a new one with your camera. Your chosen image will be scanned for text, using high-quality OCR (powered by ABBYY), and the text in the image will be inserted into ClaroSpeak. ***Minimum camera spec: 2MP*** • Word Prediction & Autocorrection Word prediction helps with writing more quickly and accurately. Train dictionaries from the current text so the best suggestions come up first. Enable Claro autocorrect and ClaroSpeak will use our specifically designed correction list to automatically correct misspelt words as they are typed. • Visual Highlighting Text is highlighted as the text is read back. Highlighting allows you to coordinate reading and listening. ClaroSpeak lets you pick the color and style of highlighting required. There are four highlighting modes to choose from: none, word by word, word trail, or sentence by sentence highlighting. • Font & Layout Change the font type, size or color to suit your needs. Layout the text for easier reading by adjusting the character, line and paragraph spacing and adjusting the page margins. Text can be formatted bold, italic and underlined to emphasize. Images can be inserted into the text from the camera or your library. • Save to Audio Convert any text into an audio file using any of the high-quality voices. This is quick and easy, allowing text to be listened to on the move. Great for proofreading on the go. • Sharing your text Text created within ClaroSpeak can be emailed, messaged, printed, opened in another app, or copied and pasted into another app, like Safari. Sending the text to Facebook and Twitter lets you join in with social media. • Read webpages You can now read webpages in Safari and other browsers, using the "Read with ClaroSpeak" extension from the share menu. • Dropbox and Google Drive Integration Open documents stored in Dropbox or Google Drive directly in ClaroSpeak.
