Constructors

RecognizerIntent(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

Fields

ActionGetLanguageDetails	A broadcast intent which can be fired to the `BroadcastReceiver` component specified in the meta-data defined in the `#DETAILS_META_DATA` meta-data of an `Activity` satisfying `#ACTION_WEB_SEARCH`.
ActionRecognizeSpeech	Starts an activity that will prompt the user for speech and send it through a speech recognizer.
ActionVoiceSearchHandsFree	Starts an activity that will prompt the user for speech without requiring the user's visual attention or touch input.
ActionWebSearch	Starts an activity that will prompt the user for speech, send it through a speech recognizer, and either display a web search result or trigger another type of action based on the user's speech.
DetailsMetaData	Meta-data name under which an `Activity` implementing `#ACTION_WEB_SEARCH` can use to expose the class name of a `BroadcastReceiver` which can respond to request for more information, from any of the broadcast intents specified in this class.
ExtraAudioInjectSource	The extra key used in an intent which is providing an already opened audio source for the RecognitionService to use.
ExtraAudioSource	Optional `android.os.ParcelFileDescriptor` pointing to an already opened audio source for the recognizer to use.
ExtraAudioSourceChannelCount	Optional integer, to be used with `#EXTRA_AUDIO_SOURCE`, to indicate the number of channels in the audio.
ExtraAudioSourceEncoding	Optional integer (from `android.media.AudioFormat`), to be used with `#EXTRA_AUDIO_SOURCE`, to indicate the audio encoding.
ExtraAudioSourceSamplingRate	Optional integer, to be used with `#EXTRA_AUDIO_SOURCE`, to indicate the sampling rate of the audio.
ExtraBiasingStrings	Optional list of strings, towards which the recognizer should bias the recognition results.
ExtraCallingPackage	The extra key used in an intent to the speech recognizer for voice search.
ExtraConfidenceScores	A float array of confidence scores of the recognition results when performing `#ACTION_RECOGNIZE_SPEECH`.
ExtraEnableBiasingDeviceContext	Optional boolean to enable biasing towards device context.
ExtraEnableFormatting	Optional string to enable text formatting (e.
ExtraEnableLanguageDetection	Optional boolean indicating whether to enable language detection.
ExtraEnableLanguageSwitch	Optional string to enable automatic switching to the language being spoken with the desired sensitivity level, instead of being restricted to a single language.
ExtraHidePartialTrailingPunctuation	Optional boolean, to be used with `#EXTRA_ENABLE_FORMATTING`, to prevent the recognizer adding punctuation after the last word of the partial results.
ExtraLanguage	Optional IETF language tag (as defined by BCP 47), for example "en-US".
ExtraLanguageDetectionAllowedLanguages	Optional list of IETF language tags (as defined by BCP 47, e.
ExtraLanguageModel	Informs the recognizer which speech model to prefer when performing `#ACTION_RECOGNIZE_SPEECH`.
ExtraLanguagePreference	The key to the extra in the `Bundle` returned by `#ACTION_GET_LANGUAGE_DETAILS` which is a `String` that represents the current language preference this user has specified - a locale string like "en-US".
ExtraLanguageSwitchAllowedLanguages	Optional list of IETF language tags (as defined by BCP 47, e.
ExtraMaskOffensiveWords	Optional boolean indicating whether the recognizer should mask the offensive words in recognition results.
ExtraMaxResults	Optional limit on the maximum number of results to return.
ExtraOnlyReturnLanguagePreference	Specify this boolean extra in a broadcast of `#ACTION_GET_LANGUAGE_DETAILS` to indicate that only the current language preference is needed in the response.
ExtraOrigin	Optional value which can be used to indicate the referer url of a page in which speech was requested.
ExtraPartialResults	Optional boolean to indicate whether partial results should be returned by the recognizer as the user speaks (default is false).
ExtraPreferOffline	Optional boolean, to be used with `#ACTION_RECOGNIZE_SPEECH`, `#ACTION_VOICE_SEARCH_HANDS_FREE`, `#ACTION_WEB_SEARCH` to indicate whether to only use an offline speech recognition engine.
ExtraPrompt	Optional text prompt to show to the user when asking them to speak.
ExtraRequestWordConfidence	Optional boolean indicating whether the recognizer should return the confidence level of each word in the final recognition results.
ExtraRequestWordTiming	Optional boolean indicating whether the recognizer should return the timestamp of each word in the final recognition results.
ExtraResults	An ArrayList<String> of the recognition results when performing `#ACTION_RECOGNIZE_SPEECH`.
ExtraResultsPendingintent	When the intent is `#ACTION_RECOGNIZE_SPEECH`, the speech input activity will return results to you via the activity results mechanism.
ExtraResultsPendingintentBundle	If you use `#EXTRA_RESULTS_PENDINGINTENT` to supply a forwarding intent, you can also use this extra to supply additional extras for the final intent.
ExtraSecure	Optional boolean to indicate that a "hands free" voice search was performed while the device was in a secure mode.
ExtraSegmentedSession	Optional string to enable segmented session mode of the specified type, which can be `#EXTRA_AUDIO_SOURCE`, `#EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS` or `#EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS`.
ExtraSpeechInputCompleteSilenceLengthMillis	The amount of time that it should take after the recognizer stops hearing speech to consider the input complete hence end the recognition session.
ExtraSpeechInputMinimumLengthMillis	Optional integer to indicate the minimum length of the recognition session.
ExtraSpeechInputPossiblyCompleteSilenceLengthMillis	The amount of time that it should take after we stop hearing speech to consider the input possibly complete.
ExtraSupportedLanguages	The key to the extra in the `Bundle` returned by `#ACTION_GET_LANGUAGE_DETAILS` which is an `ArrayList` of `String`s that represents the languages supported by this implementation of voice recognition - a list of strings like "en-US", "cmn-Hans-CN", etc.
ExtraWebSearchOnly	Optional boolean, to be used with `#ACTION_WEB_SEARCH`, to indicate whether to only fire web searches in response to a user's speech.
FormattingOptimizeLatency	Optimizes formatting latency.
FormattingOptimizeQuality	Optimizes formatting quality.
LanguageModelFreeForm	Use a language model based on free-form speech recognition.
LanguageModelWebSearch	Use a language model based on web search terms.
LanguageSwitchBalanced	A value to use for `#EXTRA_ENABLE_LANGUAGE_SWITCH`.
LanguageSwitchHighPrecision	A value to use for `#EXTRA_ENABLE_LANGUAGE_SWITCH`.
LanguageSwitchQuickResponse	A value to use for `#EXTRA_ENABLE_LANGUAGE_SWITCH`.
