Text to speech in the browser with the Web Speech API

The Web Speech API allows developers to command their browser to read out any text in a number of different voices. To start with the API, developers can use the `speechSynthesis.speak` method to get the browser to speak for the first time. The API also has a `getVoices` function that returns the available SpeechSynthesisVoice objects. These voices can be used to select the voice that the browser uses when speaking. The API emits several events, including `start`, `end`, and `animationiteration`, which can be used to add animations or other effects while the browser is speaking. With the Web Speech API, developers can build applications that use speech synthesis for a variety of purposes, such as creating in-browser chatbots or providing audio feedback to users.
