Now it's your turn: add speech capability to your app or extension today! We can't wait to hear what you come up with, and if you talk about it, please add the hashtag #chrometts so we can join the conversation.
#SPEECH TO TEXT CHROME EXTENSION INSTALL#
For now, there's unfortunately no default voice support on Linux – but TTS is fully supported once users first install a voice from the Chrome Web Store. Chrome OS comes with a built-in speech engine, too. If a user doesn't have any voices installed, Chrome automatically speaks using the native speech capabilities of your Windows or Mac operating system, if possible.

The experience is very easy for end users: just click and install one of those voices, and immediately any talking app or extension has the ability to speak using that voice. These voices both use Native Client to synthesize speech.

Here are two voices implemented using the TTS Engine API that you can install now: Your extension then takes care of synthesizing and outputting the speech – using any web technology you like, including HTML5 Audio, the new Web Audio API, or Native Client. Essentially, you provide some information about your voice in the extension manifest and then register a JavaScript function that gets called when the client calls. The TTS Engine API enables you to implement a speech engine as an extension for Chrome. So we've opened that up to developers, too. One of the most important things we wanted to do with this API was to make sure that users have a great selection of voices to choose from. Applications for Education Speak It isnt a perfect text to speech app, but it is adequate for having webpages read to students. In fact, the API is powerful enough that ChromeVox, the Chrome OS screen reader for visually impaired users, is built using this API.įinally, let's talk about flexibility for users.

All the details can be found in the TTS API docs, and we provide complete example code on the samples page. You can also get a list of possible voices and ask for a particular voice – more on this below. When a TTS engine supports it, you can get callbacks for individual words too. How about powerful? To get even fancier and synchronize speech with your application, you can register to receive callbacks when the speech starts and finishes. Here’s an example that speaks more slowly:Ĭ('Can you understand me now?', ) It’s also very easy to change the rate, pitch, and volume. With the new API, you just need to add "tts" to your permissions and then write:

A few clever apps and extensions figured out how to talk before this API was available – typically by sending text to a remote server that returns an MP3 file that can be played using HTML5 audio. Let’s start with the "simple to use" part. Interested in making your Chrome Extension (or packaged app) talk using synthesized speech? Chrome now includes a Text-to-Speech (TTS) API that’s simple to use, powerful, and flexible for users.

To implement a TTS engine, an extension must declare the "ttsEngine" permission and then declare all voices it provides in the extension manifest, like this: )Ĭhrome. An extension could even do something different with the utterances, like display closed captions in a pop-up window or send them as log messages to a remote server.

Extensions are free to use any available web technology to provide speech, including streaming audio from a server, HTML5 audio, Native Client, or Flash. By doing so, it can intercept some or all calls to functions such as tts.speak and tts.stop and provide an alternate implementation. An extension can register itself as a speech engine.
