The Web Speech API code in the browser is responsible for prompting the user for permission to record from the microphone, determine when speaking has ended, and submit the data to our speech proxy server.Here is the current architecture:Ī typical request follows the steps below: The entire backend is managed by Mozilla's cloudops and services team. Where are our servers and who manages it? Currently we have audio collection defaulted to off, but eventually would like to allow users to opt-in if they choose. This means, unlike when a user inputs speech using Chrome, their recordings are not saved and can not be attached to their profile and saved indefinitely.įor Firefox, we can choose whether we hold on to users’ data to train our own speech services. ) We opt-out of allowing Google to store our voice requests. (Google provides an FAQ for how they handle transcription data. This is intended to make it impractical for Google to associate such requests with a user account based just on the data Mozilla provides in transcription requests. Prior to sending the data to Google, however, Mozilla routes it through our own server's proxy first, in part to strip it of user identity information. Google leads the industry in this space and has speech recognition in 120 languages. Currently we are sending audio to Google’s Cloud Speech-to-Text. If you your purpose is to develop using the API, you can find the documentation on MDN.įirefox can specify which server receives the audio data inputted by the users. Then navigate to a website that makes use of the API, like Google Translate, for example, select a language, click the microphone and say something. Then type about:config in your address bar, search for the and _enable preferences and make sure they are set as true. The speech recognizer decodes the audio and sends a transcript back down to the browser to display on a page as text.įirst make sure you are running Firefox Nightly newer than 72.0a1 ().

Once they’ve finished their utterance, the browser passes the audio to a server, where it is run through a speech recognition engine. Then they can input what they want to say (an utterance). When they click it, they will be prompted to grant temporary permission for the browser to access the microphone.

It’s up to individual sites to determine how voice is integrated in their experience, how it is triggered and how to display recognition results.Īs an example, a user might see a microphone button in a text field. When a user visits a speech-enabled website, they will use that site’s UI to start the process. We’ve therefore included the work needed to start closing this gap among our 2019 OKRs for Firefox, beginning with providing WebSpeech API support in Firefox Nightly. If nothing else, our lack of support for voice experiences is a web compatibility issue that will only become more of a handicap as voice becomes more prevalent on the web. We can also offer a more private speech experience, as we do not keep identifiable information along with users’ audio recordings. It helps users because they will be able to take advantage of speech-enabled web experiences on any browser they choose. As speech input becomes more prevalent, it helps developers to have a consistent way to implement it on the web. Some examples of this include Duolingo, Google Translate, (for voice search).Ĭhrome, Edge, Safari and Opera support a form of this API currently for Speech-to-text, which means sites that rely on it work in those browsers, but not in Firefox. The speech recognition part of the WebSpeech API allows websites to enable speech input within their experiences.
