Constructor & Destructor Documentation

speech_synthesizer()

xtd::speech::synthesis::speech_synthesizer::speech_synthesizer

(

)

Initializes a new instance of the xtd::speech::synthesis::speech_synthesizer class.

Remarks

When you initialize a new xtd::speech::synthesis::speech_synthesizer instance, it uses the default system voice. To configure the xtd::speech::synthesis::speech_synthesizer to use one of the installed speech synthesis (text-to-speech) voices, use the xtd::speech::synthesis::speech_synthesizer::select_voice or xtd::speech::synthesis::speech_synthesizer::select_voice_by_hints method. To get information about which voices are installed, use the xtd::speech::synthesis::speech_synthesizer::get_installed_voices method and the xtd::speech::synthesis::voice_info class.

Member Function Documentation

state()

synthesizer_state xtd::speech::synthesis::speech_synthesizer::state ( ) const

noexcept

Gets the current speaking state of the xtd::speech::speech_synthesizer object.

Returns

Returns the current speaking state of the xtd::speech::speech_synthesizer object.

speak() [1/2]

void xtd::speech::synthesis::speech_synthesizer::speak

(

const xtd::string &

text_to_speak

)

Synchronously speaks the contents of a string.

Parameters

text_to_speak

The text to speak.

Remarks

To asynchronously speak the contents of a xtd::speech::synthesis::prompt_builder object, use xtd::speech::synthesis::speech_synthesizer::speak_async.

speak() [2/2]

void xtd::speech::synthesis::speech_synthesizer::speak

(

xtd::speech::synthesis::prompt &

prompt

)

Synchronously speaks the contents of a xtd::speech::synthesis::prompt object.

Parameters

prompt

The content to speak.

Remarks

To asynchronously speak the contents of a xtd::speech::synthesis::prompt_builder object, use xtd::speech::synthesis::speech_synthesizer::speak_async.

speak_async() [1/2]

xtd::speech::synthesis::prompt & xtd::speech::synthesis::speech_synthesizer::speak_async

(

const xtd::string &

text_to_speak

)

Asynchronously speaks the contents of a string.

Parameters

text_to_speak

The text to speak.

Returns

Returns the object that contains the content to speak.

speak_async() [2/2]

void xtd::speech::synthesis::speech_synthesizer::speak_async

(

xtd::speech::synthesis::prompt &

prompt

)

Asynchronously speaks the contents of a xtd::speech::synthesis::prompt object.

Parameters

prompt

The content to speak.

Member Data Documentation

speak_completed

event<speech_synthesizer, speak_completed_event_handler> xtd::speech::synthesis::speech_synthesizer::speak_completed

Raised when the xtd::speech::synthesis::speech_synthesizer completes the speaking of a prompt.

Remarks

The xtd::speech::synthesis::speech_synthesizer raises the xtd::speech::synthesis::speech_synthesizer::speak_completed event at the completion of any of the xtd::speech::synthesis::speech_synthesizer::speak, xtd::speech::synthesis::speech_synthesizer::speak_async, xtd::speech::synthesis::speech_synthesizer::speak_ssml, or xtd::speech::synthesis::speech_synthesizer::speak_ssml_async methods.

speak_started

event<speech_synthesizer, speak_started_event_handler> xtd::speech::synthesis::speech_synthesizer::speak_started

Raised when the xtd::speech::synthesis::speech_synthesizer begins the speaking of a prompt.

Remarks

The xtd::speech::synthesis::speech_synthesizer raises this event when it begins processing a prompt using any of the xtd::speech::synthesis::speech_synthesizer::speak, xtd::speech::synthesis::speech_synthesizer::speak_async, xtd::speech::synthesis::speech_synthesizer::speak_ssml, or xtd::speech::synthesis::speech_synthesizer::speak_ssml_async methods.

state_changed

event<speech_synthesizer, state_changed_event_handler> xtd::speech::synthesis::speech_synthesizer::state_changed

Raised when the state of the xtd::speech::synthesis::speech_synthesizer changes.

Remarks

The xtd::speech::synthesis::speech_synthesizer raises this event when its speaking xtd::speech::synthesis::speech_synthesizer::state changes. For an example and more information about data associated with the event, see xtd::speech::synthesis::state_changed_event_args.

To pause and resume speech synthesis, use the xtd::speech::synthesis::speech_synthesizer::pause and xtd::speech::synthesis::speech_synthesizer::resume methods.
