Instance Attribute Details

#alternative_language_codesArray<String>

Optional A list of up to 3 additional BCP-47 language tags, listing possible alternative languages of the supplied audio. See Language Support for a list of the currently supported language codes. If alternative languages are listed, recognition result will contain recognition in the most likely language detected including the main language_code. The recognition result will include the language tag of the language detected in the audio. Note: This feature is only supported for Voice Command and Voice Search use cases and performance may vary for other use cases (e.g., phone call transcription). Corresponds to the JSON property alternativeLanguageCodes

Returns:

  • (Array<String>)

#audio_channel_countFixnum

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'. Corresponds to the JSON property audioChannelCount

Returns:

  • (Fixnum)

#diarization_configGoogle::Apis::SpeechV1p1beta1::SpeakerDiarizationConfig

Optional Config to enable speaker diarization and set additional parameters to make diarization better suited for your application. Note: When this is enabled, we send all the words from the beginning of the audio for the top alternative in every consecutive STREAMING responses. This is done in order to improve our speaker tags as our models learn to identify the speakers in the conversation over time. For non-streaming requests, the diarization results will be provided only in the top alternative of the FINAL SpeechRecognitionResult. Corresponds to the JSON property diarizationConfig

#diarization_speaker_countFixnum

Optional If set, specifies the estimated number of speakers in the conversation. If not set, defaults to '2'. Ignored unless enable_speaker_diarization is set to true." Note: Use diarization_config instead. This field will be DEPRECATED soon. Corresponds to the JSON property diarizationSpeakerCount

#enable_automatic_punctuationBoolean 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)

#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)

#enable_speaker_diarizationBoolean Also known as: enable_speaker_diarization?

#enable_word_time_offsetsBoolean 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

#max_alternativesFixnum

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

#modelString

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

#profanity_filterBoolean Also known as: profanity_filter?

#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 and required for all other audio formats. For details, see AudioEncoding. Corresponds to the JSON property sampleRateHertz

Returns:

  • (Fixnum)

#use_enhancedBoolean 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)
