SLT is a female US English text-to-speech (TTS) voice extension that runs in your browser using Native Client technology.
This extention provides the "SLT" female American English voice for Chrome. The extension does not do anything by itself. Use it with other extensions that provide Text-To-Speech or Screen Reading functionality!
Flite (festival-lite) is a small, fast run-time synthesis engine developed at Carnegie Mellon University. The synthesis engine runs directly in your browser using Native Client technology. Thus you can use Flite voices even without network connectivity.
You can find a male voice here: https://chrome.google.com/webstore/detail/mcaliakhpofpiofabjknimmmfgfgcdid
If you are an extension developer, please note that Flite voices support the "word" event, so if you are synthesizing a paragraph of text, for example, you could show progress as the audio gets played.
