For example, you can make the voice sound more robotic, or like a giant ogre, or an evil demon.
Want more voices? You can download the generated audio and then use voicechanger.io to add effects to the voice. If you don't like the externally-downloaded voice, you can use a recording app on your device to record the 'system' or 'internal' sound while you're playing the generated voice audio. You can download the audio as a file, but note that the downloaded voices may be different to your browser's voices because they are downloaded from an external text-to-speech server.
This web app allows you to generate voice audio from text - no login needed, and it's completely free! It uses your browser's built-in voice synthesis technology, and so the voices will differ depending on the browser that you're using.
