Speak Thai is a free Chrome extension developed by Luke. It falls under the category of Browsers and specifically belongs to the Add-ons & Tools subcategory. This extension serves as a handy tool for those who understand spoken Thai but struggle with reading the Thai script.

The main functionality of Speak Thai is to read out selected Thai text using Google text-to-speech technology. To use the extension, simply follow these steps: select the desired Thai text, right-click, and choose "Speak Thai" from the context menu. Alternatively, you can also use the keyboard shortcut control+alt+s (Windows) or command+alt+s (Mac) after selecting the text.

It is important to note that Speak Thai currently only works for short snippets of text. The extension utilizes the text-to-speech engine from Google Translate to generate the spoken Thai output.
