Instance Attribute Details

#audio_channel_countFixnum

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'. Corresponds to the JSON property audioChannelCount

Returns:

  • (Fixnum)

#diarization_configGoogle::Apis::SpeechV1::SpeakerDiarizationConfig

Config to enable speaker diarization. Corresponds to the JSON property diarizationConfig

  @diarization_config
end

#enable_automatic_punctuationBoolean Also known as: enable_automatic_punctuation?

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. Corresponds to the JSON property enableAutomaticPunctuation

Returns:

  • (Boolean)

# File 'lib/google/apis/speech_v1/classes.rb', line 281

  @enable_automatic_punctuation
end

#enable_separate_recognition_per_channelBoolean Also known as: enable_separate_recognition_per_channel?

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. The request is billed cumulatively for all channels recognized: audio_channel_count multiplied by the length of the audio. Corresponds to the JSON property enableSeparateRecognitionPerChannel

Returns:

  • (Boolean)

end

#enable_word_time_offsetsBoolean Also known as: enable_word_time_offsets?

If true, the top result includes a list of words and the start and end time offsets (timestamps) for those words. If false, no word-level time offset information is returned. The default is false. Corresponds to the JSON property enableWordTimeOffsets

Returns:

  • (Boolean)

#encodingString

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. Corresponds to the JSON property encoding

Returns:

  • (String)

# File 'lib/google/apis/speech_v1/classes.rb', line 308

  @encoding
end

#language_codeString

Required. The language of the supplied audio as a BCP-47 language tag. Example: "en-US". See Language Support for a list of the currently supported language codes. Corresponds to the JSON property languageCode

Returns:

  • (String)

  @language_code
end

#max_alternativesFixnum

Maximum number of recognition hypotheses to be returned. Specifically, the maximum number of SpeechRecognitionAlternative messages within each SpeechRecognitionResult. The server may return fewer than max_alternatives. Valid values are 0-30. A value of 0 or 1 will return a maximum of one. If omitted, will return a maximum of one. Corresponds to the JSON property maxAlternatives

Returns:

  • (Fixnum)

#metadataGoogle::Apis::SpeechV1::RecognitionMetadata

def 
  @metadata
end

#modelString

Which model to select for the given request. Select the model best suited to your domain to get best results. If a model is not explicitly specified, then we auto-select a model based on the parameters in the RecognitionConfig. * Model* Description command_and_search Best for short queries such as voice commands or voice search. phone_call Best for audio that originated from a phone call (typically recorded at an 8khz sampling rate). video Best for audio that originated from video or includes multiple speakers. Ideally the audio is recorded at a 16khz or greater sampling rate. This is a premium model that costs more than the standard rate. default Best for audio that is not one of the specific audio models. For example, long-form audio. Ideally the audio is high-fidelity, recorded at a 16khz or greater sampling rate. Corresponds to the JSON property model

Returns:

  • (String)

def model
  @model
end

#profanity_filterBoolean Also known as: profanity_filter?

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***" . If set to false or omitted, profanities won't be filtered out. Corresponds to the JSON property profanityFilter

Returns:

  • (Boolean)

# File 'lib/google/apis/speech_v1/classes.rb', line 352

def profanity_filter
  @profanity_filter
end

#sample_rate_hertzFixnum

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. Corresponds to the JSON property sampleRateHertz

Returns:

  • (Fixnum)

# File 'lib/google/apis/speech_v1/classes.rb', line 363

def sample_rate_hertz
  @sample_rate_hertz
end

#speech_contextsArray<Google::Apis::SpeechV1::SpeechContext>

Array of SpeechContext. A means to provide context to assist the speech recognition. For more information, see speech adaptation. Corresponds to the JSON property speechContexts

# File 'lib/google/apis/speech_v1/classes.rb', line 370

def speech_contexts
  @speech_contexts
end

#use_enhancedBoolean Also known as: use_enhanced?

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. Corresponds to the JSON property useEnhanced

Returns:

  • (Boolean)
