Using speech synthesis

Although every attempt has been made to ensure the correctness and reasonableness of the information and tools provided here, we remind you that you use this website entirely at your own risk.

All of the teaching tools on this website make use of the speech synthesis capability of recent browsers so that our students may become familiar with spoken American English. To use this capability, click or tap on the button labeled with the 🔊 icon on the tool panels.

As a demonstration, you can tap or click on to launch an instance of the Pronouncer tool. (The tool will not be launchable if you have disabled popups for our website.) Enter some text and press the button with the 🔊 icon on the tool panel to hear the entered text "read" using speech synthesis. (Note that English voices expect valid English words, and, therefore, may "read" incorrectly spelled words incorrectly.) To close the Pronouncer tool panel, simply click on its close button, usually labeled with the × symbol, either on the right or left of its title bar (the topmost strip of its window).

All of the teaching tools are also equipped with voice controls, which are accessed by clicking on the ⓥ label, to the left of the buttons in the tool panel. In most cases, the voice controls will allow you to regulate the speed of the generated speech (from 50% to 100%) and the speech volume (from 0% to 100%, although this may be overridden by your device's controls). Depending upon the browser that you are using, you may also be able to select between two or more voices. We note that some voices—such as that available with the Google Chrome browser—are only available when your device (desktop, laptop, notebook, tablet, smartphone, etc.) has an active Internet connection.
