Overview

    Package polly provides the API client, operations, and parameter types for Amazon Polly.

    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.

    Functions

    func NewDefaultEndpointResolver

    func NewDefaultEndpointResolver() *internalendpoints.Resolver

      NewDefaultEndpointResolver constructs a new service endpoint resolver

      func WithAPIOptions

      func WithAPIOptions(optFns ...func(*middleware.Stack) error) func(*Options)

        WithAPIOptions returns a functional option for setting the Client's APIOptions option.

        func WithEndpointResolver

        func WithEndpointResolver(v EndpointResolver) func(*Options)

          WithEndpointResolver returns a functional option for setting the Client's EndpointResolver option.

          Types

          type Client

          type Client struct {
          	// contains filtered or unexported fields
          }

            Client provides the API client to make operations call for Amazon Polly.

            func New

            func New(options Options, optFns ...func(*Options)) *Client

              New returns an initialized Client based on the functional options. Provide additional functional options to further configure the behavior of the client, such as changing the client's endpoint or adding custom middleware behavior.

              func NewFromConfig

              func NewFromConfig(cfg aws.Config, optFns ...func(*Options)) *Client

                NewFromConfig returns a new client from the provided config.

                func (*Client) DeleteLexicon

                func (c *Client) DeleteLexicon(ctx context.Context, params *DeleteLexiconInput, optFns ...func(*Options)) (*DeleteLexiconOutput, error)

                  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 (https://docs.aws.amazon.com/polly/latest/dg/managing-lexicons.html).

                  func (*Client) DescribeVoices

                  func (c *Client) DescribeVoices(ctx context.Context, params *DescribeVoicesInput, optFns ...func(*Options)) (*DescribeVoicesOutput, error)

                    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.

                    func (*Client) GetLexicon

                    func (c *Client) GetLexicon(ctx context.Context, params *GetLexiconInput, optFns ...func(*Options)) (*GetLexiconOutput, error)

                      Returns the content of the specified pronunciation lexicon stored in an AWS Region. For more information, see Managing Lexicons (https://docs.aws.amazon.com/polly/latest/dg/managing-lexicons.html).

                      func (*Client) GetSpeechSynthesisTask

                      func (c *Client) GetSpeechSynthesisTask(ctx context.Context, params *GetSpeechSynthesisTaskInput, optFns ...func(*Options)) (*GetSpeechSynthesisTaskOutput, error)

                        Retrieves a specific SpeechSynthesisTask object based on its TaskID. This object contains information about the given speech synthesis task, including the status of the task, and a link to the S3 bucket containing the output of the task.

                        func (*Client) ListLexicons

                        func (c *Client) ListLexicons(ctx context.Context, params *ListLexiconsInput, optFns ...func(*Options)) (*ListLexiconsOutput, error)

                          Returns a list of pronunciation lexicons stored in an AWS Region. For more information, see Managing Lexicons (https://docs.aws.amazon.com/polly/latest/dg/managing-lexicons.html).

                          func (*Client) ListSpeechSynthesisTasks

                          func (c *Client) ListSpeechSynthesisTasks(ctx context.Context, params *ListSpeechSynthesisTasksInput, optFns ...func(*Options)) (*ListSpeechSynthesisTasksOutput, error)

                            Returns a list of SpeechSynthesisTask objects ordered by their creation date. This operation can filter the tasks by their status, for example, allowing users to list only tasks that are completed.

                            func (*Client) PutLexicon

                            func (c *Client) PutLexicon(ctx context.Context, params *PutLexiconInput, optFns ...func(*Options)) (*PutLexiconOutput, error)

                              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 (https://docs.aws.amazon.com/polly/latest/dg/managing-lexicons.html).

                              func (*Client) StartSpeechSynthesisTask

                              func (c *Client) StartSpeechSynthesisTask(ctx context.Context, params *StartSpeechSynthesisTaskInput, optFns ...func(*Options)) (*StartSpeechSynthesisTaskOutput, error)

                                Allows the creation of an asynchronous synthesis task, by starting a new SpeechSynthesisTask. This operation requires all the standard information needed for speech synthesis, plus the name of an Amazon S3 bucket for the service to store the output of the synthesis task and two optional parameters (OutputS3KeyPrefix and SnsTopicArn). Once the synthesis task is created, this operation will return a SpeechSynthesisTask object, which will include an identifier of this task as well as the current status.

                                func (*Client) SynthesizeSpeech

                                func (c *Client) SynthesizeSpeech(ctx context.Context, params *SynthesizeSpeechInput, optFns ...func(*Options)) (*SynthesizeSpeechOutput, error)

                                  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 (https://docs.aws.amazon.com/polly/latest/dg/how-text-to-speech-works.html).

                                  }

                                    EndpointResolver interface for resolving service endpoints.

                                    func EndpointResolverFromURL

                                    func EndpointResolverFromURL(url string, optFns ...func(*aws.Endpoint)) EndpointResolver

                                      EndpointResolverFromURL returns an EndpointResolver configured using the provided endpoint url. By default, the resolved endpoint resolver uses the client region as signing region, and the endpoint source is set to EndpointSourceCustom.You can provide functional options to configure endpoint values for the resolved endpoint.

                                      type EndpointResolverFunc

                                      type EndpointResolverFunc func(region string, options EndpointResolverOptions) (aws.Endpoint, error)

                                        EndpointResolverFunc is a helper utility that wraps a function so it satisfies the EndpointResolver interface. This is useful when you want to add additional endpoint resolving logic, or stub out specific endpoints with custom values.

                                        func (EndpointResolverFunc) ResolveEndpoint

                                        func (fn EndpointResolverFunc) ResolveEndpoint(region string, options EndpointResolverOptions) (endpoint aws.Endpoint, err error)

                                        type EndpointResolverOptions

                                        type EndpointResolverOptions = internalendpoints.Options

                                          EndpointResolverOptions is the service endpoint resolver options
