RecognitionConfig class

Provides information to the recognizer that specifies how to process the request.

RecognitionConfig.fromJson(Map json_)

Properties

adaptation ↔ SpeechAdaptation?

Speech adaptation configuration improves the accuracy of speech recognition.

getter/setter pair

alternativeLanguageCodes ↔ List<String>?

A list of up to 3 additional [BCP-47](https://www.rfc-editor.org/rfc/bcp/bcp47.txt) language tags, listing possible alternative languages of the supplied audio.

getter/setter pair

audioChannelCount ↔ int?

The number of channels in the input audio data.

getter/setter pair

diarizationConfig ↔ SpeakerDiarizationConfig?

Config to enable speaker diarization and set additional parameters to make diarization better suited for your application.

getter/setter pair

enableAutomaticPunctuation ↔ bool?

If 'true', adds punctuation to recognition result hypotheses.

getter/setter pair

enableSeparateRecognitionPerChannel ↔ bool?

This needs to be set to true explicitly and audio_channel_count > 1 to get each channel recognized separately.

getter/setter pair

enableSpokenEmojis ↔ bool?

The spoken emoji behavior for the call If not set, uses default behavior based on model of choice If 'true', adds spoken emoji formatting for the request.

getter/setter pair

enableSpokenPunctuation ↔ bool?

The spoken punctuation behavior for the call If not set, uses default behavior based on model of choice e.g. command_and_search will enable spoken punctuation by default If 'true', replaces spoken punctuation with the corresponding symbols in the request.

getter/setter pair

enableWordConfidence ↔ bool?

If true, the top result includes a list of words and the confidence for those words.

getter/setter pair

enableWordTimeOffsets ↔ bool?

If true, the top result includes a list of words and the start and end time offsets (timestamps) for those words.

getter/setter pair

encoding ↔ String?

Encoding of audio data sent in all RecognitionAudio messages.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

languageCode ↔ String?

The language of the supplied audio as a [BCP-47](https://www.rfc-editor.org/rfc/bcp/bcp47.txt) language tag.

getter/setter pair

maxAlternatives ↔ int?

Maximum number of recognition hypotheses to be returned.

getter/setter pair

metadata ↔ RecognitionMetadata?

Metadata regarding this request.

getter/setter pair

model ↔ String?

Which model to select for the given request.

getter/setter pair

profanityFilter ↔ bool?

If set to true, the server will attempt to filter out profanities, replacing all but the initial character in each filtered word with asterisks, e.g. "f***".

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

sampleRateHertz ↔ int?

Sample rate in Hertz of the audio data sent in all RecognitionAudio messages.

getter/setter pair

speechContexts ↔ List<SpeechContext>?

Array of SpeechContext.

getter/setter pair

transcriptNormalization ↔ TranscriptNormalization?

Use transcription normalization to automatically replace parts of the transcript with phrases of your choosing.

getter/setter pair

useEnhanced ↔ bool?

Set to true to use an enhanced model for speech recognition.

getter/setter pair
