setSampleRateHertz(int value)

public RecognitionConfig.Builder setSampleRateHertz(int value)

Sample rate in Hertz of the audio data sent in all RecognitionAudio messages. Valid values are: 8000-48000. 16000 is optimal. For best results, set the sampling rate of the audio source to 16000 Hz. If that's not possible, use the native sample rate of the audio source (instead of re-sampling). This field is optional for FLAC and WAV audio files, but is required for all other audio formats. For details, see AudioEncoding.

int32 sample_rate_hertz = 2;

Parameter
Name Description
value int

The sampleRateHertz to set.

setTranscriptNormalization(TranscriptNormalization value)

public RecognitionConfig.Builder setTranscriptNormalization(TranscriptNormalization value)

Optional. Use transcription normalization to automatically replace parts of the transcript with phrases of your choosing. For StreamingRecognize, this normalization only applies to stable partial transcripts (stability > 0.8) and final transcripts.

.google.cloud.speech.v1.TranscriptNormalization transcript_normalization = 24 [(.google.api.field_behavior) = OPTIONAL];

Parameter
Name Description
value TranscriptNormalization
Returns
Type Description

setTranscriptNormalization(TranscriptNormalization.Builder builderForValue)

public RecognitionConfig.Builder setTranscriptNormalization(TranscriptNormalization.Builder builderForValue)

Optional. Use transcription normalization to automatically replace parts of the transcript with phrases of your choosing. For StreamingRecognize, this normalization only applies to stable partial transcripts (stability > 0.8) and final transcripts.

.google.cloud.speech.v1.TranscriptNormalization transcript_normalization = 24 [(.google.api.field_behavior) = OPTIONAL];

setUseEnhanced(boolean value)

public RecognitionConfig.Builder setUseEnhanced(boolean value)

Set to true to use an enhanced model for speech recognition. If use_enhanced is set to true and the model field is not set, then an appropriate enhanced model is chosen if an enhanced model exists for the audio.

If use_enhanced is true and an enhanced version of the specified model does not exist, then the speech is recognized using the standard version of the specified model.

bool use_enhanced = 14;

Parameter
Name Description
value boolean

The useEnhanced to set.
