VozMe is a simple online application which converts a block of typed text into an accompanying sound file (mp3). To use VozMe, all you need to do is type or cut and paste text into the provided text block and click "generate mp3". The service works with text in both Spanish and English. When you're the sound bite has been created, an external window will pop up and your file will play automatically. You'll also be provided with the option of downloading the mp3 file. If you're a webmaster (or maybe, if you just have a blog), you can also embed the sound file into your page in a variety of ways in a variety of formats (reference the "Webmaster") section of the site for detailed, step-by-step instructions.
