Instance Attribute Details

#enable_automatic_punctuation ⇒ Boolean Also known as: enable_automatic_punctuation?

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. Corresponds to the JSON property enableAutomaticPunctuation

Returns:

  • (Boolean)

end

#enable_word_time_offsets ⇒ Boolean Also known as: enable_word_time_offsets?

Optional 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)

end

#encoding ⇒ String

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)

  @encoding
end

#language_code ⇒ String

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_alternatives ⇒ Fixnum

Optional 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)

  @max_alternatives
end

#model ⇒ String

Optional 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 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)

end

#profanity_filter ⇒ Boolean Also known as: profanity_filter?

Optional 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)

  @profanity_filter
end

#sample_rate_hertz ⇒ Fixnum

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. Corresponds to the JSON property sampleRateHertz

Returns:

  • (Fixnum)

end

#speech_contexts ⇒ Array<Google::Apis::SpeechV1::SpeechContext>

Optional array of SpeechContext. A means to provide context to assist the speech recognition. For more information, see Phrase Hints. Corresponds to the JSON property speechContexts

Returns:

# File 'generated/google/apis/speech_v1/classes.rb', line 385

def speech_contexts
  @speech_contexts
end

#use_enhanced ⇒ Boolean Also known as: use_enhanced?

Optional 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:

  1. project is eligible for requesting enhanced models
  2. 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. Enhanced speech models require that you opt-in to data logging using instructions in the documentation. If you set use_enhanced to true and you have not enabled audio logging, then you will receive an error. Corresponds to the JSON property useEnhanced

Returns:

  • (Boolean)
