#alternative_language_codesArray<String>

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

The number of channels in the input audio data. ONLY set this for MULTI- CHANNEL recognition. Valid values for LINEAR16, OGG_OPUS and FLAC are 1-8. 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)

#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.

#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)

#modelString

Which model to select for the given request. Select the model best suited to your domain to get best results.

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. medical_conversation Best for audio that originated from a conversation between a medical provider and patient. medical_dictation Best for audio that originated from dictation notes by a medical provider.

#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, but is 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?

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)
