In documentation and tutorial for REST API (Google Sppech API for Node: https://cloud.google.com/nodejs/apis), so my question is how to use the Cloud Speech API in JavaScript. Someone used on any page with javascript?
2020-04-24 EDIT: The accepted answer is using webkitSpeechRecognition
which is not available on mobile: https://stackoverflow.com/a/61039699/775359
Google documentation and examples: https://cloud.google.com/speech-to-text/docs/samples
Node.js code: https://github.com/googleapis/nodejs-speech/blob/master/samples/MicrophoneStream.js
REQUIREMENT: it has to run in Safari on iOS.
The Google Cloud API is more specifically used for server-side speech processing. If you're looking to use voice recognition through a browser, you should use your browser's built in Web Speech API. Here's a simple example:
var recognition = new webkitSpeechRecognition();
recognition.continuous = true;
var output = document.getElementById('output');
recognition.onresult = function(event) {
output.textContent = event.results[0][0].transcript;
};
<div id="output"></div>
<button onclick="recognition.start()">Start</button>
<button onclick="recognition.stop()">Stop</button>
