Chrome Web Speech APIs

Google has not ceased to amaze us with their products aimed at making our lives easier and better. The launch of Chrome version 25 in 2013 has remained a discussion ever since that a browser could actually “listen and talk.” Google Chrome web speech API feature is behind this phenomenon breakthrough.

The Chrome speech API is a set of tools written in JavaScript that allows you to add speech recognition to your website when using Chrome browser. The API is also able to read out text on your webpages.

How Google Chrome web speech APIs works

To get started, you must create an account with Google Cloud Platform. Under the API and Service request for an API access key, you can build and use the API. Search for a speech recognition service and get started.

By default, Google Chrome web speech API is built in JavaScript. However it is possible to customize to a language that you are comfortable. The HTTP request method is used in creating calls, and JSON is the preferred data format for responses.

Chrome speech API first checks to verify whether the browser you are using supports speech recognition. To do this, the API checks whether your browser window has a webkitSpeechRecognition object. If absent, the API will bring you an error message to upgrade to Chrome version 25 or later.

When present, the API will request permission to use the microphone to get started. Once the user clicks on the microphone, the API will type what it hears based on the browser’s language setting. The API continuously type speech until there is a pause. After you are done, the API prompts you to copy and paste the text or send it directly as an email.


Developers continually integrate this feature into their websites and applications for greater reach and efficiency. People with tight schedules and require fast typing find web voice API useful and convenient. People with difficulties in reading text use the API to read out the contents of webpages.
