Overview

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

Service 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.

Sending a Request Using Polly

var polly = new AWS.Polly();
polly.deleteLexicon(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 Polly object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var polly = new AWS.Polly({apiVersion: '2016-06-10'});

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

AWS.config.apiVersions = {
  polly: '2016-06-10',
  // other service API versions
};

var polly = new AWS.Polly();

var polly = new AWS.Polly({apiVersion: '2016-06-10'});

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|AWS.Endpoint) —

    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' or an Endpoint object.

  • 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.

    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.Polly.region 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.

    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'.

Method Details

deleteLexicon(params = {}, callback) ⇒ AWS.Request

Deletes the specified pronunciation lexicon stored in an Amazon Web Services 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.

Service Reference:

Examples:

To delete a lexicon


/* Deletes a specified pronunciation lexicon stored in an AWS Region. */

 var params = {

   else     console.log(data);           // successful response
   /*
   data = {
   }
   */
 });

Calling the deleteLexicon operation

var params = {
  Name: 'STRING_VALUE' /* required */
};
polly.deleteLexicon(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • Name — (String)

      The name of the lexicon to delete. Must be an existing lexicon in the region.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

describeVoices(params = {}, callback) ⇒ AWS.Request

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.

putLexicon(params = {}, callback) ⇒ AWS.Request

Stores a pronunciation lexicon in an Amazon Web Services 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.

Service Reference:

Examples:

To save a lexicon


/* Stores a pronunciation lexicon in an AWS Region. */

 var params = {
  Content: "file://example.pls", 
  Name: "W3C"
 };
 polly.putLexicon(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
   /*
   data = {
   }
   */
 });

Calling the putLexicon operation

var params = {
  Content: 'STRING_VALUE', /* required */
  Name: 'STRING_VALUE' /* required */
};
polly.putLexicon(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • Name — (String)

      Name of the lexicon. The name must follow the regular express format [0-9A-Za-z]{1,20}. That is, the name is a case-sensitive alphanumeric string up to 20 characters long.

    • Content — (String)

      Content of the PLS lexicon as string data.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

startSpeechSynthesisTask(params = {}, callback) ⇒ AWS.Request

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. The SpeechSynthesisTask object is available for 72 hours after starting the asynchronous synthesis task.

synthesizeSpeech(params = {}, callback) ⇒ AWS.Request

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:

  • params (Object) (defaults to: {}) —
    • Engine — (String)

      Specifies the engine (standard or neural) for Amazon Polly to use when processing input text for speech synthesis. For information on Amazon Polly voices and which voices are available in standard-only, NTTS-only, and both standard and NTTS formats, see Available Voices.

      NTTS-only voices

      When using NTTS-only voices such as Kevin (en-US), this parameter is required and must be set to neural. If the engine is not specified, or is set to standard, this will result in an error.

      Type: String

      Valid Values: standard | neural

      Required: Yes

      Standard voices

      For standard voices, this is not required; the engine parameter defaults to standard. If the engine is not specified, or is set to standard and an NTTS-only voice is selected, this will result in an error.

      Possible values include:
      • "standard"
      • "neural"
    • LanguageCode — (String)

      Optional language code for the Synthesize Speech request. This is only necessary if using a bilingual voice, such as Aditi, which can be used for either Indian English (en-IN) or Hindi (hi-IN).

      If a bilingual voice is used and no language code is specified, Amazon Polly uses the default language of the bilingual voice. The default language for any voice is the one returned by the DescribeVoices operation for the LanguageCode parameter. For example, if no language code is specified, Aditi will use Indian English rather than Hindi.

      Possible values include:
      • "arb"
      • "cmn-CN"
      • "cy-GB"
      • "da-DK"

      • "en-NZ"
      • "en-ZA"
    • LexiconNames — (Array<String>)

      List of one or more pronunciation lexicon names you want the service to apply during synthesis. Lexicons are applied only if the language of the lexicon is the same as the language of the voice. For information about storing lexicons, see PutLexicon.

    • OutputFormat — (String)

      The format in which the returned output will be encoded. For audio stream, this will be mp3, ogg_vorbis, or pcm. For speech marks, this will be json.

      When pcm is used, the content returned is audio/pcm in a signed 16-bit, 1 channel (mono), little-endian format.

      Possible values include:
      • "json"
      • "mp3"
      • "ogg_vorbis"
      • "pcm"
    • SampleRate — (String)

      The audio frequency specified in Hz.

      The valid values for mp3 and ogg_vorbis are "8000", "16000", "22050", and "24000". The default value for standard voices is "22050". The default value for neural voices is "24000".

      Valid values for pcm are "8000" and "16000" The default value is "16000".

    • SpeechMarkTypes — (Array<String>)

      The type of speech marks returned for the input text.

    • Text — (String)

      Input text to synthesize. If you specify ssml as the TextType, follow the SSML format for the input text.

    • TextType — (String)

      Specifies whether the input text is plain text or SSML. The default value is plain text. For more information, see Using SSML.

      Possible values include:
      • "ssml"
      • "text"
    • VoiceId — (String)

      Voice ID to use for the synthesis. You can get a list of available voice IDs by calling the DescribeVoices operation.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • AudioStream — (Buffer(Node.js), Typed Array(Browser), ReadableStream)

        Stream containing the synthesized speech.

      • ContentType — (String)

        Specifies the type audio stream. This should reflect the OutputFormat parameter in your request.

        • If you request mp3 as the OutputFormat, the ContentType returned is audio/mpeg.

        • If you request ogg_vorbis as the OutputFormat, the ContentType returned is audio/ogg.

        • If you request pcm as the OutputFormat, the ContentType returned is audio/pcm in a signed 16-bit, 1 channel (mono), little-endian format.

        • If you request json as the OutputFormat, the ContentType returned is audio/json.

      • RequestCharacters — (Integer)

        Number of characters synthesized.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.
