@Generated("software.amazon.awssdk:codegen")
public interface PollyAsyncClient
extends AutoCloseable

Service client for accessing null asynchronously. This can be created using the static builder() method.

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.

Method Detail

create

static PollyAsyncClient create()

Create a PollyAsyncClient with the region loaded from the DefaultAwsRegionProviderChain and credentials loaded from the DefaultCredentialsProvider.

builder

static PollyAsyncClientBuilder builder()

Create a builder that can be used to configure and create a PollyAsyncClient.

deleteLexicon

default CompletableFuture<DeleteLexiconResponse> deleteLexicon(DeleteLexiconRequest deleteLexiconRequest)

Deletes the specified pronunciation lexicon stored in an AWS Region. A lexicon which has been deleted is not available for speech synthesis, nor is it possible to retrieve it using either the GetLexicon or ListLexicon APIs.

For more information, see Managing Lexicons.

Parameters:

deleteLexiconRequest -

Returns:

A Java Future containing the result of the DeleteLexicon operation returned by the service.
The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.

• LexiconNotFoundException Amazon Polly can't find the specified lexicon. This could be caused by a lexicon that is missing, its name is misspelled or specifying a lexicon that is in a different region.

  Verify that the lexicon exists, is in the region (see ListLexicons) and that you spelled its name is spelled correctly. Then try again.

• ServiceFailureException An unknown condition has caused a service failure.
• SdkBaseException Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
• SdkClientException If any client side error occurs such as an IO related failure, failure to get credentials, etc
• PollyException Base class for all service exceptions. Unknown exceptions will be thrown as an instance of this

describeVoices

default CompletableFuture<DescribeVoicesResponse> describeVoices(DescribeVoicesRequest describeVoicesRequest)

Returns the list of voices that are available for use when requesting speech synthesis. Each voice speaks a specified language, is either male or female, and is identified by an ID, which is the ASCII version of the voice name.

When synthesizing speech ( SynthesizeSpeech ), you provide the voice ID for the voice you want from the list of voices returned by DescribeVoices.

For example, you want your news reader application to read news in a specific language, but giving a user the option to choose the voice. Using the DescribeVoices operation you can provide the user with a list of available voices to select from.

You can optionally specify a language code to filter the available voices. For example, if you specify en-US, the operation returns a list of all available US English voices.

This operation requires permissions to perform the polly:DescribeVoices action.

Parameters:

describeVoicesRequest -

Returns:

A Java Future containing the result of the DescribeVoices operation returned by the service.
The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.

• InvalidNextTokenException The NextToken is invalid. Verify that it's spelled correctly, and then try again.
• ServiceFailureException An unknown condition has caused a service failure.
• SdkBaseException Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
• SdkClientException If any client side error occurs such as an IO related failure, failure to get credentials, etc
• PollyException Base class for all service exceptions. Unknown exceptions will be thrown as an instance of this

Parameters:

listLexiconsRequest -

Returns:

A Java Future containing the result of the ListLexicons operation returned by the service.
The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.

putLexicon

default CompletableFuture<PutLexiconResponse> putLexicon(PutLexiconRequest putLexiconRequest)

Stores a pronunciation lexicon in an AWS Region. If a lexicon with the same name already exists in the region, it is overwritten by the new lexicon. Lexicon operations have eventual consistency, therefore, it might take some time before the lexicon is available to the SynthesizeSpeech operation.

For more information, see Managing Lexicons.

Parameters:

putLexiconRequest -

Returns:

A Java Future containing the result of the PutLexicon operation returned by the service.
The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.

• InvalidLexiconException Amazon Polly can't find the specified lexicon. Verify that the lexicon's name is spelled correctly, and then try again.
• UnsupportedPlsAlphabetException The alphabet specified by the lexicon is not a supported alphabet. Valid values are x-sampa and ipa.
• UnsupportedPlsLanguageException The language specified in the lexicon is unsupported. For a list of supported languages, see Lexicon Attributes.
• LexiconSizeExceededException The maximum size of the specified lexicon would be exceeded by this operation.
• MaxLexemeLengthExceededException The maximum size of the lexeme would be exceeded by this operation.
• MaxLexiconsNumberExceededException The maximum number of lexicons would be exceeded by this operation.
• ServiceFailureException An unknown condition has caused a service failure.
• SdkBaseException Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
• SdkClientException If any client side error occurs such as an IO related failure, failure to get credentials, etc

synthesizeSpeech

default <ReturnT> CompletableFuture<ReturnT> synthesizeSpeech(SynthesizeSpeechRequest synthesizeSpeechRequest,
                                                              AsyncResponseHandler<SynthesizeSpeechResponse,ReturnT> asyncResponseHandler)

Synthesizes UTF-8 input, plain text or SSML, to a stream of bytes. SSML input must be valid, well-formed SSML. Some alphabets might not be available with all the voices (for example, Cyrillic might not be read at all by English voices) unless phoneme mapping is used. For more information, see How it Works.

Parameters:

synthesizeSpeechRequest -

asyncResponseHandler - The response handler for processing the streaming response in a non-blocking manner. See AsyncResponseHandler for details on how this callback should be implemented and for links to precanned implementations for common scenarios like downloading to a file. The service documentation for the streamed content is as follows '

Stream containing the synthesized speech.

'.

Returns:

A future to the transformed result of the AsyncResponseHandler.
The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.

• TextLengthExceededException The value of the "Text" parameter is longer than the accepted limits. The limit for input text is a maximum of 3000 characters total, of which no more than 1500 can be billed characters. SSML tags are not counted as billed characters.
• InvalidSampleRateException The specified sample rate is not valid.
• InvalidSsmlException The SSML you provided is invalid. Verify the SSML syntax, spelling of tags and values, and then try again.
• LexiconNotFoundException Amazon Polly can't find the specified lexicon. This could be caused by a lexicon that is missing, its name is misspelled or specifying a lexicon that is in a different region.

  Verify that the lexicon exists, is in the region (see ListLexicons) and that you spelled its name is spelled correctly. Then try again.

• ServiceFailureException An unknown condition has caused a service failure.
• MarksNotSupportedForFormatException Speech marks are not supported for the OutputFormat selected. Speech marks are only available for content in json format.
• SsmlMarksNotSupportedForTextTypeException SSML speech marks are not supported for plain text-type input.
