Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Operations and objects for transcribing speech to text.

Sending a Request Using TranscribeService

var transcribeservice = new AWS.TranscribeService();
transcribeservice.createVocabulary(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the TranscribeService object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var transcribeservice = new AWS.TranscribeService({apiVersion: '2017-10-26'});

You can also set the API version globally in AWS.config.apiVersions using the transcribeservice service identifier:

AWS.config.apiVersions = {
  transcribeservice: '2017-10-26',
  // other service API versions
};

var transcribeservice = new AWS.TranscribeService();

Examples:

Constructing a TranscribeService object

var transcribeservice = new AWS.TranscribeService({apiVersion: '2017-10-26'});

Options Hash (options):

  • params (map)

    An optional map of parameters to bind to every request sent by this service object. For more information on bound parameters, see "Working with Services" in the Getting Started Guide.

  • endpoint (String)

    The endpoint URI to send requests to. The default endpoint is built from the configured region. The endpoint should be a string like 'https://{service}.{region}.amazonaws.com'.

  • accessKeyId (String)

    your AWS access key ID.

  • secretAccessKey (String)

    your AWS secret access key.

  • sessionToken (AWS.Credentials)

    the optional AWS session token to sign requests with.

  • credentials (AWS.Credentials)

    the AWS credentials to sign requests with. You can either specify this object, or specify the accessKeyId and secretAccessKey options directly.

  • credentialProvider (AWS.CredentialProviderChain)

    the provider chain used to resolve credentials if no static credentials property is set.

  • region (String)

    the region to send service requests to. See AWS.TranscribeService.region for more information.

  • maxRetries (Integer)

    the maximum amount of retries to attempt with a request. See AWS.TranscribeService.maxRetries for more information.

  • maxRedirects (Integer)

    the maximum amount of redirects to follow with a request. See AWS.TranscribeService.maxRedirects for more information.

  • sslEnabled (Boolean)

    whether to enable SSL for requests.

  • paramValidation (Boolean|map)

    whether input parameters should be validated against the operation description before sending the request. Defaults to true. Pass a map to enable any of the following specific validation features:

    • min [Boolean] — Validates that a value meets the min constraint. This is enabled by default when paramValidation is set to true.
    • max [Boolean] — Validates that a value meets the max constraint.
    • pattern [Boolean] — Validates that a string value matches a regular expression.
    • enum [Boolean] — Validates that a string value matches one of the allowable enum values.
  • computeChecksums (Boolean)

    whether to compute checksums for payload bodies when the service accepts it (currently supported in S3 only)

  • convertResponseTypes (Boolean)

    whether types are converted when parsing response data. Currently only supported for JSON based services. Turning this off may improve performance on large response payloads. Defaults to true.

  • correctClockSkew (Boolean)

    whether to apply a clock skew correction and retry requests that fail because of an skewed client clock. Defaults to false.

  • s3ForcePathStyle (Boolean)

    whether to force path style URLs for S3 objects.

  • s3BucketEndpoint (Boolean)

    whether the provided endpoint addresses an individual bucket (false if it addresses the root API endpoint). Note that setting this configuration option requires an endpoint to be provided explicitly to the service constructor.

  • s3DisableBodySigning (Boolean)

    whether S3 body signing should be disabled when using signature version v4. Body signing can only be disabled when using https. Defaults to true.

  • retryDelayOptions (map)

    A set of options to configure the retry delay on retryable errors. Currently supported options are:

    • base [Integer] — The base number of milliseconds to use in the exponential backoff for operation retries. Defaults to 100 ms for all services except DynamoDB, where it defaults to 50ms.
    • customBackoff [function] — A custom function that accepts a retry count and returns the amount of time to delay in milliseconds. The base option will be ignored if this option is supplied.
  • httpOptions (map)

    A set of options to pass to the low-level HTTP request. Currently supported options are:

    • proxy [String] — the URL to proxy requests through
    • agent [http.Agent, https.Agent] — the Agent object to perform HTTP requests with. Used for connection pooling. Defaults to the global agent (http.globalAgent) for non-SSL connections. Note that for SSL connections, a special Agent object is used in order to enable peer certificate verification. This feature is only available in the Node.js environment.
    • connectTimeout [Integer] — Sets the socket to timeout after failing to establish a connection with the server after connectTimeout milliseconds. This timeout has no effect once a socket connection has been established.
    • timeout [Integer] — Sets the socket to timeout after timeout milliseconds of inactivity on the socket. Defaults to two minutes (120000).
    • xhrAsync [Boolean] — Whether the SDK will send asynchronous HTTP requests. Used in the browser environment only. Set to false to send requests synchronously. Defaults to true (async on).
    • xhrWithCredentials [Boolean] — Sets the "withCredentials" property of an XMLHttpRequest object. Used in the browser environment only. Defaults to false.
  • apiVersion (String, Date)

    a String in YYYY-MM-DD format (or a date) that represents the latest possible API version that can be used in all services (unless overridden by apiVersions). Specify 'latest' to use the latest possible version.

  • apiVersions (map<String, String|Date>)

    a map of service identifiers (the lowercase service class name) with the API version to use when instantiating a service. Specify 'latest' for each individual that can use the latest available version.

  • logger (#write, #log)

    an object that responds to .write() (like a stream) or .log() (like the console object) in order to log information about requests

  • systemClockOffset (Number)

    an offset value in milliseconds to apply to all signing times. Use this to compensate for clock skew when your system may be out of sync with the service time. Note that this configuration option can only be applied to the global AWS.config object and cannot be overridden in service-specific configuration. Defaults to 0 milliseconds.

  • signatureVersion (String)

    the signature version to sign requests with (overriding the API configuration). Possible values are: 'v2', 'v3', 'v4'.

  • signatureCache (Boolean)

    whether the signature to sign requests with (overriding the API configuration) is cached. Only applies to the signature version 'v4'. Defaults to true.

  • dynamoDbCrc32 (Boolean)

    whether to validate the CRC32 checksum of HTTP response bodies returned by DynamoDB. Default: true.

  • useAccelerateEndpoint (Boolean)

    Whether to use the S3 Transfer Acceleration endpoint with the S3 service. Default: false.

  • clientSideMonitoring (Boolean)

    whether to collect and publish this client's performance metrics of all its API requests.

  • endpointDiscoveryEnabled (Boolean)

    whether to enable endpoint discovery for operations that allow optionally using an endpoint returned by the service. Defaults to 'false'

          • The media format provided does not match the detected media format - The media format of the audio file doesn't match the format specified in the MediaFormat field in the request. Check the media format of your media file and make sure that the two values match.

          • Invalid sample rate for audio file - The sample rate specified in the MediaSampleRateHertz of the request isn't valid. The sample rate must be between 8000 and 48000 Hertz.

          • The sample rate provided does not match the detected sample rate - The sample rate in the audio file doesn't match the sample rate specified in the MediaSampleRateHertz field in the request. Check the sample rate of your media file and make sure that the two values match.

          • Invalid file size: file size too large - The size of your audio file is larger than Amazon Transcribe can process. For more information, see Limits in the Amazon Transcribe Developer Guide.

          • Invalid number of channels: number of channels too large - Your audio contains more channels than Amazon Transcribe is configured to process. To request additional channels, see Amazon Transcribe Limits in the Amazon Web Services General Reference.

        • Settings — (map)

          Optional settings for the transcription job. Use these settings to turn on speaker recognition, to set the maximum number of speakers that should be identified and to specify a custom vocabulary to use when processing the transcription job.

          • VocabularyName — (String)

            The name of a vocabulary to use when processing the transcription job.

          • ShowSpeakerLabels — (Boolean)

            Determines whether the transcription job uses speaker recognition to identify different speakers in the input audio. Speaker recognition labels individual speakers in the audio file. If you set the ShowSpeakerLabels field to true, you must also set the maximum number of speaker labels MaxSpeakerLabels field.

            You can't set both ShowSpeakerLabels and ChannelIdentification in the same request. If you set both, your request returns a BadRequestException.

          • MaxSpeakerLabels — (Integer)

            The maximum number of speakers to identify in the input audio. If there are more speakers in the audio than this number, multiple speakers will be identified as a single speaker. If you specify the MaxSpeakerLabels field, you must set the ShowSpeakerLabels field to true.

          • ChannelIdentification — (Boolean)

            Instructs Amazon Transcribe to process each audio channel separately and then merge the transcription output of each channel into a single transcription.

            Amazon Transcribe also produces a transcription of each item detected on an audio channel, including the start time and end time of the item and alternative transcriptions of the item including the confidence that Amazon Transcribe has in the transcription.

            You can't set both ShowSpeakerLabels and ChannelIdentification in the same request. If you set both, your request returns a BadRequestException.

    • OutputBucketName — (String)

      The location where the transcription is stored.

      If you set the OutputBucketName, Amazon Transcribe puts the transcription in the specified S3 bucket. When you call the GetTranscriptionJob operation, the operation returns this location in the TranscriptFileUri field. The S3 bucket must have permissions that allow Amazon Transcribe to put files in the bucket. For more information, see Permissions Required for IAM User Roles.

      Amazon Transcribe uses the default Amazon S3 key for server-side encryption of transcripts that are placed in your S3 bucket. You can't specify your own encryption key.

      If you don't set the OutputBucketName, Amazon Transcribe generates a pre-signed URL, a shareable URL that provides secure access to your transcription, and returns it in the TranscriptFileUri field. Use this URL to download the transcription.

    • Settings — (map)

      A Settings object that provides optional settings for a transcription job.

      • VocabularyName — (String)

        The name of a vocabulary to use when processing the transcription job.

      • ShowSpeakerLabels — (Boolean)

        Determines whether the transcription job uses speaker recognition to identify different speakers in the input audio. Speaker recognition labels individual speakers in the audio file. If you set the ShowSpeakerLabels field to true, you must also set the maximum number of speaker labels MaxSpeakerLabels field.

        You can't set both ShowSpeakerLabels and ChannelIdentification in the same request. If you set both, your request returns a BadRequestException.

      • MaxSpeakerLabels — (Integer)

        The maximum number of speakers to identify in the input audio. If there are more speakers in the audio than this number, multiple speakers will be identified as a single speaker. If you specify the MaxSpeakerLabels field, you must set the ShowSpeakerLabels field to true.

      • ChannelIdentification — (Boolean)

        Instructs Amazon Transcribe to process each audio channel separately and then merge the transcription output of each channel into a single transcription.

        Amazon Transcribe also produces a transcription of each item detected on an audio channel, including the start time and end time of the item and alternative transcriptions of the item including the confidence that Amazon Transcribe has in the transcription.

        You can't set both ShowSpeakerLabels and ChannelIdentification in the same request. If you set both, your request returns a BadRequestException.
