Properties

AuthorizationToken	Gets/sets authorization token used to communicate with the service. Note: The caller needs to ensure that the authorization token is valid. Before the authorization token expires, the caller needs to refresh it by calling this setter with a new valid token. Otherwise, the synthesizer will encounter errors while speech synthesis. Added in 1.7.0
Properties	The collection of properties and their values defined for this SpeechSynthesizer. Note: The property collection is only valid until the SpeechSynthesizer owning this Properties is disposed or finalized.

Methods

Dispose()	Dispose of associated resources.
Finalize()
GetVoicesAsync(String)	Get the available voices. Added in 1.16.0
SpeakAsync(SpeechSynthesisRequest)	Execute the speech synthesis on request, asynchronously. This API could be used to synthesize speech from an input text stream, to reduce latency for text generation scenarios. Note: the feature is in preview and is subject to change. Added in version 1.37.0
SpeakSsmlAsync(String)	Synthesize speech from SSML asynchronously (returns when done synthesizing).
SpeakTextAsync(String)	Synthesize speech from plain text asynchronously (returns when done synthesizing).
StartSpeakingAsync(SpeechSynthesisRequest)	Queue the speech synthesis on request, as an asynchronous operation. This API could be used to synthesize speech from an input text stream, to reduce latency for text generation scenarios. Note: the feature is in preview and is subject to change. Added in version 1.37.0
StartSpeakingSsmlAsync(String)	Queue speech synthesis task from SSML as an asynchronous operation.
StartSpeakingTextAsync(String)	Queue speech synthesis task from plain text as an asynchronous operation.
StopSpeakingAsync()	Stop speech synthesis.

Events

BookmarkReached	Signals that a bookmark was reached. Added in 1.16.0
SynthesisCanceled	Signals that the speech synthesis was canceled.
SynthesisCompleted	Signals that speech synthesis has completed.
SynthesisStarted	Signals that speech synthesis has started.
Synthesizing	Signals that speech synthesis is ongoing. This event fires each time the SDK receives an audio chunk from the Speech service.
VisemeReceived	Signals that a viseme event was received. Added in 1.16.0
WordBoundary	Signals that a word boundary was received. Added in 1.7.0
