Amazon Polly¶

Description¶

Amazon Polly is a web service that makes it easy to synthesize speech from text.

The Amazon Polly service provides API operations for synthesizing high-quality speech from plain text and Speech Synthesis Markup Language (SSML), along with managing pronunciations lexicons that enable you to get the best results for your application domain.

Usage¶

polly(config = list(), credentials = list(), endpoint = NULL, region = NULL)

Arguments¶

config

Optional configuration of credentials, endpoint, and/or region.
- credentials:
  - creds:
    - access_key_id: AWS access key ID
    - secret_access_key: AWS secret access key
    - session_token: AWS temporary session token
  - profile: The name of a profile to use. If not given, then the default profile is used.
  - anonymous: Set anonymous credentials.
- endpoint: The complete URL to use for the constructed client.
- region: The AWS Region used in instantiating the client.
- close_connection: Immediately close all HTTP connections.
- timeout: The time in seconds till a timeout exception is thrown when attempting to make a connection. The default is 60 seconds.
- s3_force_path_style: Set this to true to force the request to use path-style addressing, i.e. http://s3.amazonaws.com/BUCKET/KEY.
- sts_regional_endpoint: Set sts regional endpoint resolver to regional or legacy https://docs.aws.amazon.com/sdkref/latest/guide/feature-sts-regionalized-endpoints.html
- use_dual_stack: Set this to true to use the dualstack (IPv4 and IPv6) endpoint for a service, where available, falling back to the regular endpoint when it isn't. Defaults to the AWS_USE_DUALSTACK_ENDPOINT environment variable when unset.
credentials

Optional credentials shorthand for the config parameter
- creds:
  - access_key_id: AWS access key ID
  - secret_access_key: AWS secret access key
  - session_token: AWS temporary session token
- profile: The name of a profile to use. If not given, then the default profile is used.
- anonymous: Set anonymous credentials.
endpoint

Optional shorthand for complete URL to use for the constructed client.
region

Optional shorthand for AWS Region used in instantiating the client.

Value¶

A client for the service. You can call the service's operations using syntax like svc$operation(...), where svc is the name you've assigned to the client. The available operations are listed in the Operations section.

      session_token = "string"
    ),
    profile = "string",
    anonymous = "logical"
  ),

  region = "string"
)

Operations¶

`delete_lexicon`	Deletes the specified pronunciation lexicon stored in an Amazon Web Services Region
`describe_voices`	Returns the list of voices that are available for use when requesting speech synthesis
`get_lexicon`	Returns the content of the specified pronunciation lexicon stored in an Amazon Web Services Region
`get_speech_synthesis_task`	Retrieves a specific SpeechSynthesisTask object based on its TaskID
`list_lexicons`	Returns a list of pronunciation lexicons stored in an Amazon Web Services Region
`list_speech_synthesis_tasks`	Returns a list of SpeechSynthesisTask objects ordered by their creation date
`put_lexicon`	Stores a pronunciation lexicon in an Amazon Web Services Region
`start_speech_synthesis_stream`	Synthesizes UTF-8 input, plain text, or SSML over a bidirectional streaming connection
`start_speech_synthesis_task`	Allows the creation of an asynchronous synthesis task, by starting a new SpeechSynthesisTask
`synthesize_speech`	Synthesizes UTF-8 input, plain text or SSML, to a stream of bytes

Examples¶

svc <- polly()
# Deletes a specified pronunciation lexicon stored in an AWS Region.
svc$delete_lexicon(
  Name = "example"
)
