    • languageCustomizationId

      public String languageCustomizationId()
      Gets the languageCustomizationId.

      The customization ID (GUID) of a custom language model that is to be used with the recognition request. The base model of the specified custom language model must match the model specified with the `model` parameter. You must make the request with credentials for the instance of the service that owns the custom model. By default, no custom language model is used. See [Custom models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#custom-input).

      **Note:** Use this parameter instead of the deprecated `customization_id` parameter.

      Returns:
      the languageCustomizationId

    • acousticCustomizationId

      public String acousticCustomizationId()
      Gets the acousticCustomizationId.

      The customization ID (GUID) of a custom acoustic model that is to be used with the recognition request. The base model of the specified custom acoustic model must match the model specified with the `model` parameter. You must make the request with credentials for the instance of the service that owns the custom model. By default, no custom acoustic model is used. See [Custom models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#custom-input).

      Returns:
      the acousticCustomizationId

    • baseModelVersion

      public String baseModelVersion()
      Gets the baseModelVersion.

      The version of the specified base model that is to be used with the recognition request. Multiple versions of a base model can exist when a model is updated for internal improvements. The parameter is intended primarily for use with custom models that have been upgraded for a new base model. The default value depends on whether the parameter is used with or without a custom model. See [Base model version](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#version).

      Returns:
      the baseModelVersion

    • customizationWeight

      public Double customizationWeight()
      Gets the customizationWeight.

      If you specify the customization ID (GUID) of a custom language model with the recognition request, the customization weight tells the service how much weight to give to words from the custom language model compared to those from the base model for the current request.

      Specify a value between 0.0 and 1.0. Unless a different customization weight was specified for the custom model when it was trained, the default value is 0.3. A customization weight that you specify overrides a weight that was specified when the custom model was trained.

      The default value yields the best performance in general. Assign a higher value if your audio makes frequent use of OOV words from the custom model. Use caution when setting the weight: a higher value can improve the accuracy of phrases from the custom model's domain, but it can negatively affect performance on non-domain phrases.

      See [Custom models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#custom-input).

      Returns:
      the customizationWeight

    • inactivityTimeout

      public Long inactivityTimeout()
      Gets the inactivityTimeout.

      The time in seconds after which, if only silence (no speech) is detected in streaming audio, the connection is closed with a 400 error. The parameter is useful for stopping audio submission from a live microphone when a user simply walks away. Use `-1` for infinity. See [Inactivity timeout](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#timeouts-inactivity).

      Returns:
      the inactivityTimeout

    • keywords

      public List<String> keywords()
      Gets the keywords.

      An array of keyword strings to spot in the audio. Each keyword string can include one or more string tokens. Keywords are spotted only in the final results, not in interim hypotheses. If you specify any keywords, you must also specify a keywords threshold. Omit the parameter or specify an empty array if you do not need to spot keywords.

      You can spot a maximum of 1000 keywords with a single request. A single keyword can have a maximum length of 1024 characters, though the maximum effective length for double-byte languages might be shorter. Keywords are case-insensitive.

      See [Keyword spotting](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#keyword_spotting).

      Returns:
      the keywords

    • keywordsThreshold

      public Float keywordsThreshold()
      Gets the keywordsThreshold.

      A confidence value that is the lower bound for spotting a keyword. A word is considered to match a keyword if its confidence is greater than or equal to the threshold. Specify a probability between 0.0 and 1.0. If you specify a threshold, you must also specify one or more keywords. The service performs no keyword spotting if you omit either parameter. See [Keyword spotting](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#keyword_spotting).

      Returns:
      the keywordsThreshold

    • maxAlternatives

      public Long maxAlternatives()
      Gets the maxAlternatives.

      The maximum number of alternative transcripts that the service is to return. By default, the service returns a single transcript. If you specify a value of `0`, the service uses the default value, `1`. See [Maximum alternatives](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#max_alternatives).

      Returns:
      the maxAlternatives

    • wordAlternativesThreshold

      public Float wordAlternativesThreshold()
      Gets the wordAlternativesThreshold.

      A confidence value that is the lower bound for identifying a hypothesis as a possible word alternative (also known as "Confusion Networks"). An alternative word is considered if its confidence is greater than or equal to the threshold. Specify a probability between 0.0 and 1.0. By default, the service computes no alternative words. See [Word alternatives](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#word_alternatives).

      Returns:
      the wordAlternativesThreshold

    • wordConfidence

      public Boolean wordConfidence()
      Gets the wordConfidence.

      If `true`, the service returns a confidence measure in the range of 0.0 to 1.0 for each word. By default, the service returns no word confidence scores. See [Word confidence](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#word_confidence).

      Returns:
      the wordConfidence

    • timestamps

      public Boolean timestamps()
      Gets the timestamps.

      If `true`, the service returns time alignment for each word. By default, no timestamps are returned. See [Word timestamps](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#word_timestamps).

      Returns:
      the timestamps

    • profanityFilter

      public Boolean profanityFilter()
      Gets the profanityFilter.

      If `true`, the service filters profanity from all output except for keyword results by replacing inappropriate words with a series of asterisks. Set the parameter to `false` to return results with no censoring. Applies to US English transcription only. See [Profanity filtering](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#profanity_filter).

      Returns:
      the profanityFilter

    • smartFormatting

      public Boolean smartFormatting()
      Gets the smartFormatting.

      If `true`, the service converts dates, times, series of digits and numbers, phone numbers, currency values, and internet addresses into more readable, conventional representations in the final transcript of a recognition request. For US English, the service also converts certain keyword strings to punctuation symbols. By default, the service performs no smart formatting.

      **Note:** Applies to US English, Japanese, and Spanish transcription only.

      See [Smart formatting](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#smart_formatting).

      Returns:
      the smartFormatting

    • speakerLabels

      public Boolean speakerLabels()
      Gets the speakerLabels.

      If `true`, the response includes labels that identify which words were spoken by which participants in a multi-person exchange. By default, the service returns no speaker labels. Setting `speaker_labels` to `true` forces the `timestamps` parameter to be `true`, regardless of whether you specify `false` for the parameter.

      **Note:** Applies to US English, Australian English, German, Japanese, Korean, and Spanish (both broadband and narrowband models) and UK English (narrowband model) transcription only.

      See [Speaker labels](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#speaker_labels).

      Returns:
      the speakerLabels

    • customizationId

      public String customizationId()
      Gets the customizationId.

      **Deprecated.** Use the `language_customization_id` parameter to specify the customization ID (GUID) of a custom language model that is to be used with the recognition request. Do not specify both parameters with a request.

      Returns:
      the customizationId

    • grammarName

      public String grammarName()
      Gets the grammarName.

      The name of a grammar that is to be used with the recognition request. If you specify a grammar, you must also use the `language_customization_id` parameter to specify the name of the custom language model for which the grammar is defined. The service recognizes only strings that are recognized by the specified grammar; it does not recognize other custom words from the model's words resource. See [Grammars](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#grammars-input).

      Returns:
      the grammarName

    • redaction

      public Boolean redaction()
      Gets the redaction.

      If `true`, the service redacts, or masks, numeric data from final transcripts. The feature redacts any number that has three or more consecutive digits by replacing each digit with an `X` character. It is intended to redact sensitive numeric data, such as credit card numbers. By default, the service performs no redaction.

      When you enable redaction, the service automatically enables smart formatting, regardless of whether you explicitly disable that feature. To ensure maximum security, the service also disables keyword spotting (ignores the `keywords` and `keywords_threshold` parameters) and returns only a single final transcript (forces the `max_alternatives` parameter to be `1`).

      **Note:** Applies to US English, Japanese, and Korean transcription only.

      See [Numeric redaction](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#redaction).

      Returns:
      the redaction

    • audioMetrics

      public Boolean audioMetrics()
      Gets the audioMetrics.

      If `true`, requests detailed information about the signal characteristics of the input audio. The service returns audio metrics with the final transcription results. By default, the service returns no audio metrics.

      See [Audio metrics](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-metrics#audio_metrics).

      Returns:
      the audioMetrics

    • endOfPhraseSilenceTime

      public Double endOfPhraseSilenceTime()
      Gets the endOfPhraseSilenceTime.

      If `true`, specifies the duration of the pause interval at which the service splits a transcript into multiple final results. If the service detects pauses or extended silence before it reaches the end of the audio stream, its response can include multiple final results. Silence indicates a point at which the speaker pauses between spoken words or phrases.

      Specify a value for the pause interval in the range of 0.0 to 120.0. * A value greater than 0 specifies the interval that the service is to use for speech recognition. * A value of 0 indicates that the service is to use the default interval. It is equivalent to omitting the parameter.

      The default pause interval for most languages is 0.8 seconds; the default for Chinese is 0.6 seconds.

      See [End of phrase silence time](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#silence_time).

      Returns:
      the endOfPhraseSilenceTime

    • splitTranscriptAtPhraseEnd

      public Boolean splitTranscriptAtPhraseEnd()
      Gets the splitTranscriptAtPhraseEnd.

      If `true`, directs the service to split the transcript into multiple final results based on semantic features of the input, for example, at the conclusion of meaningful phrases such as sentences. The service bases its understanding of semantic features on the base language model that you use with a request. Custom language models and grammars can also influence how and where the service splits a transcript. By default, the service splits transcripts based solely on the pause interval.

      See [Split transcript at phrase end](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-output#split_transcript).

      Returns:
      the splitTranscriptAtPhraseEnd

    • speechDetectorSensitivity

      public Float speechDetectorSensitivity()
      Gets the speechDetectorSensitivity.

      The sensitivity of speech activity detection that the service is to perform. Use the parameter to suppress word insertions from music, coughing, and other non-speech events. The service biases the audio it passes for speech recognition by evaluating the input audio against prior models of speech and non-speech activity.

      Specify a value between 0.0 and 1.0: * 0.0 suppresses all audio (no speech is transcribed). * 0.5 (the default) provides a reasonable compromise for the level of sensitivity. * 1.0 suppresses no audio (speech detection sensitivity is disabled).

      The values increase on a monotonic curve. See [Speech Activity Detection](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#detection).

      Returns:
      the speechDetectorSensitivity

    • backgroundAudioSuppression

      public Float backgroundAudioSuppression()
      Gets the backgroundAudioSuppression.

      The level to which the service is to suppress background audio based on its volume to prevent it from being transcribed as speech. Use the parameter to suppress side conversations or background noise.

      Specify a value in the range of 0.0 to 1.0: * 0.0 (the default) provides no suppression (background audio suppression is disabled). * 0.5 provides a reasonable level of audio suppression for general usage. * 1.0 suppresses all audio (no audio is transcribed).

      The values increase on a monotonic curve. See [Speech Activity Detection](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-input#detection).

      Returns:
      the backgroundAudioSuppression

    • interimResults

      public Boolean interimResults()
      Gets the interimResults.

      If `true`, the service returns interim results as a stream of `SpeechRecognitionResults` objects. By default, the service returns a single `SpeechRecognitionResults` object with final results only.

      NOTE: This parameter only works for the `recognizeUsingWebSocket` method.

      Returns:
      the interimResults

    • processingMetrics

      public Boolean processingMetrics()
      Gets the processingMetrics.

      If `true`, requests processing metrics about the service's transcription of the input audio. The service returns processing metrics at the interval specified by the `processing_metrics_interval` parameter. It also returns processing metrics for transcription events, for example, for final and interim results. By default, the service returns no processing metrics.

      NOTE: This parameter only works for the `recognizeUsingWebSocket` method.

      Returns:
      the processingMetrics

    • processingMetricsInterval

      public Float processingMetricsInterval()
      Gets the processingMetricsInterval.

      Specifies the interval in real wall-clock seconds at which the service is to return processing metrics. The parameter is ignored unless the `processing_metrics` parameter is set to `true`.

      The parameter accepts a minimum value of 0.1 seconds. The level of precision is not restricted, so you can specify values such as 0.25 and 0.125.

      The service does not impose a maximum value. If you want to receive processing metrics only for transcription events instead of at periodic intervals, set the value to a large number. If the value is larger than the duration of the audio, the service returns processing metrics only for transcription events.

      NOTE: This parameter only works for the `recognizeUsingWebSocket` method.

      Returns:
      the processingMetricsInterval
