AWS SDK for PHP 3.x

Client: Aws\TranscribeService\TranscribeServiceClient

Service ID: transcribe

Version: 2017-10-26

This page describes the parameters and results for the operations of the Amazon Transcribe Service (2017-10-26), and shows how to use the Aws\TranscribeService\TranscribeServiceClient object to call the described operations. This documentation is specific to the 2017-10-26 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

CreateVocabulary ( array $params = [] )
Creates a new custom vocabulary that you can use to change the way Amazon Transcribe handles transcription of an audio file.
DeleteTranscriptionJob ( array $params = [] )
Deletes a previously submitted transcription job along with any other generated results such as the transcription, models, and so on.
DeleteVocabulary ( array $params = [] )
Deletes a vocabulary from Amazon Transcribe.
GetTranscriptionJob ( array $params = [] )
Returns information about a transcription job.
GetVocabulary ( array $params = [] )
Gets information about a vocabulary.
ListTranscriptionJobs ( array $params = [] )
Lists transcription jobs with the specified status.
ListVocabularies ( array $params = [] )
Returns a list of vocabularies that match the specified criteria.
StartTranscriptionJob ( array $params = [] )
Starts an asynchronous job to transcribe speech to text.
UpdateVocabulary ( array $params = [] )
Updates an existing vocabulary with new values.

Paginators

Paginators handle automatically iterating over paginated API results. Paginators are associated with specific API operations, and they accept the parameters that the corresponding API operation accepts. You can get a paginator from a client class using getPaginator($paginatorName, $operationParameters). This client supports the following paginators:

ListTranscriptionJobs
ListVocabularies

Parameter Details

Members

LanguageCode

Required: Yes
Type: string

The language code for the language used in the input media file.

Media

Required: Yes
Type: Media structure

An object that describes the input media for a transcription job.

MediaFormat

Type: string

The format of the input media file.

If you do not specify the format of the media file, Amazon Transcribe determines the format. If the format is not recognized, Amazon Transcribe returns an InternalFailureException exception. If you specify the format, it must match the format detected by Amazon Transcribe, otherwise you get an InternalFailureException exception.

MediaSampleRateHertz

Type: int

The sample rate of the audio track in the input media file in Hertz.

If you do not specify the media sample rate, Amazon Transcribe determines the sample rate. If you specify the sample rate, it must match the sample rate detected by Amazon Transcribe. In most cases, you should leave the MediaSampleRateHertz field blank and let Amazon Transcribe determine the sample rate.

OutputBucketName

Type: 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

Type: Settings structure

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

TranscriptionJobName

Required: Yes
Type: string

The name of the job. Note that you can't use the strings "." or ".." by themselves as the job name. The name must also be unique within an AWS account.
