What is the Speech Synthesis API? The Web Speech API enables web developers to incorporate speech recognition and synthesis into their web applications. These are available via the SpeechRecognition and SpeechSynthesis interfaces. High-fidelity speech synthesis. It applies DeepMind’s groundbreaking research in WaveNet and Google’s powerful neural networks to deliver high fidelity audio. With this easy-to-use API, you can create lifelike interactions with your users, across many applications and devices.
You can also click the padlock and “Site settings” at the bottom to open a new tab that shows the entire list of Chrome permissions for just that particular domain, and you can change all the permissions from there too.
