Method Detail

getEncodingValue

int getEncodingValue()

 Encoding of audio data sent in all `RecognitionAudio` messages.
 This field is optional for `FLAC` and `WAV` audio files and required
 for all other audio formats. For details, see [AudioEncoding][google.cloud.speech.v1p1beta1.RecognitionConfig.AudioEncoding].
 

.google.cloud.speech.v1p1beta1.RecognitionConfig.AudioEncoding encoding = 1;

getEncoding

RecognitionConfig.AudioEncoding getEncoding()

 Encoding of audio data sent in all `RecognitionAudio` messages.
 This field is optional for `FLAC` and `WAV` audio files and required
 for all other audio formats. For details, see [AudioEncoding][google.cloud.speech.v1p1beta1.RecognitionConfig.AudioEncoding].
 

.google.cloud.speech.v1p1beta1.RecognitionConfig.AudioEncoding encoding = 1;

getSampleRateHertz

int getSampleRateHertz()

 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 and required
 for all other audio formats. For details, see [AudioEncoding][google.cloud.speech.v1p1beta1.RecognitionConfig.AudioEncoding].
 

int32 sample_rate_hertz = 2;

getAudioChannelCount

int getAudioChannelCount()

 *Optional* The number of channels in the input audio data.
 ONLY set this for MULTI-CHANNEL recognition.
 Valid values for LINEAR16 and FLAC are `1`-`8`.
 Valid values for OGG_OPUS are '1'-'254'.
 Valid value for MULAW, AMR, AMR_WB and SPEEX_WITH_HEADER_BYTE is only `1`.
 If `0` or omitted, defaults to one channel (mono).
 NOTE: We only recognize the first channel by default.
 To perform independent recognition on each channel set
 enable_separate_recognition_per_channel to 'true'.
 

int32 audio_channel_count = 7;

getEnableSeparateRecognitionPerChannel

boolean getEnableSeparateRecognitionPerChannel()

 This needs to be set to ‘true’ explicitly and audio_channel_count > 1
 to get each channel recognized separately. The recognition result will
 contain a channel_tag field to state which channel that result belongs to.
 If this is not ‘true’, we will only recognize the first channel.
 NOTE: The request is also billed cumulatively for all channels recognized:
     (audio_channel_count times the audio length)
 

bool enable_separate_recognition_per_channel = 12;

getLanguageCode

 language_code. The recognition result will include the language tag
 of the language detected in the audio.

getProfanityFilter

boolean getProfanityFilter()

 *Optional* If set to `true`, the server will attempt to filter out

getEnableAutomaticPunctuation

boolean getEnableAutomaticPunctuation()

 *Optional* If 'true', adds punctuation to recognition result hypotheses.
 This feature is only available in select languages. Setting this for
 requests in other languages has no effect at all.
 The default 'false' value does not add punctuation to result hypotheses.
 NOTE: "This is currently offered as an experimental service, complimentary
 to all users. In the future this may be exclusively available as a
 premium feature."
 

bool enable_automatic_punctuation = 11;

getEnableSpeakerDiarization

boolean getEnableSpeakerDiarization()

 *Optional* If 'true', enables speaker detection for each recognized word in
 the top alternative of the recognition result using a speaker_tag provided
 in the WordInfo.
 Note: When this is true, we send all the words from the beginning of the
 audio for the top alternative in every consecutive responses.
 This is done in order to improve our speaker tags as our models learn to
 identify the speakers in the conversation over time.

getUseEnhanced

boolean getUseEnhanced()

 *Optional* Set to true to use an enhanced model for speech recognition.
 You must also set the `model` field to a valid, enhanced model. If
 `use_enhanced` is set to true and the `model` field is not set, then
 `use_enhanced` is ignored. 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.
 Enhanced speech models require that you opt-in to the audio logging using
 instructions in the [alpha documentation](/speech/data-sharing). If you set
 `use_enhanced` to true and you have not enabled audio logging, then you
 will receive an error.
 

bool use_enhanced = 14;
