The Web Speech API enables you to incorporate voice data into web apps. The Web Speech API has two parts: SpeechSynthesis (Text-to-Speech), and SpeechRecognition (Asynchronous Speech Recognition.)
The Web Speech API makes web apps able to handle voice data. There are two components to this API:
SpeechRecognition interface, which provides the ability to recognize voice context from an audio input (normally via the device's default speech recognition service) and respond appropriately. Generally you'll use the interface's constructor to create a new SpeechRecognition object, which has a number of event handlers available for detecting when speech is input through the device's microphone. The SpeechGrammar interface represents a container for a particular set of grammar that your app should recognize. Grammar is defined using JSpeech Grammar Format (JSGF.)SpeechSynthesis interface, a text-to-speech component that allows programs to read out their text content (normally via the device's default speech synthesizer.) Different voice types are represented by SpeechSynthesisVoice objects, and different parts of text that you want to be spoken are represented by SpeechSynthesisUtterance objects. You can get these spoken by passing them to the SpeechSynthesis.speak() method.For more details on using these features, see Using the Web Speech API.
Web Speech API Interfaces Speech recognitionSpeechRecognition
The controller interface for the recognition service; this also handles the SpeechRecognitionEvent sent from the recognition service.
SpeechRecognitionAlternative
Represents a single word that has been recognized by the speech recognition service.
SpeechRecognitionErrorEvent
Represents error messages from the recognition service.
SpeechRecognitionEvent
The event object for the result and nomatch events, and contains all the data associated with an interim or final speech recognition result.
SpeechGrammar
The words or patterns of words that we want the recognition service to recognize.
SpeechGrammarList
Represents a list of SpeechGrammar objects.
SpeechRecognitionResult
Represents a single recognition match, which may contain multiple SpeechRecognitionAlternative objects.
SpeechRecognitionResultList
Represents a list of SpeechRecognitionResult objects, or a single one if results are being captured in continuous mode.
SpeechSynthesis
The controller interface for the speech service; this can be used to retrieve information about the synthesis voices available on the device, start and pause speech, and other commands besides.
SpeechSynthesisErrorEvent
Contains information about any errors that occur while processing SpeechSynthesisUtterance objects in the speech service.
SpeechSynthesisEvent
Contains information about the current state of SpeechSynthesisUtterance objects that have been processed in the speech service.
SpeechSynthesisUtterance
Represents a speech request. It contains the content the speech service should read and information about how to read it (e.g., language, pitch and volume.)
SpeechSynthesisVoice
Represents a voice that the system supports. Every SpeechSynthesisVoice has its own relative speech service including information about language, name and URI.
Window.speechSynthesis
Specified out as part of a [NoInterfaceObject] interface called SpeechSynthesisGetter, and Implemented by the Window object, the speechSynthesis property provides access to the SpeechSynthesis controller, and therefore the entry point to speech synthesis functionality.
For information on errors reported by the Speech API (for example, "language-not-supported" and "language-unavailable"), see the following documentation:
