Overview

An API client for Polly. To construct a client, you need to configure a :region and :credentials.

client = Aws::Polly::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the developer guide.

See #initialize for a full list of supported configuration options.

#initialize(options) ⇒ Client

Returns a new instance of Client.

Parameters:

  • options (Hash)

Options Hash (options):

  • :plugins (Array<Seahorse::Client::Plugin>) — default: []] —

    A list of plugins to apply to the client. Each plugin is either a class name or an instance of a plugin class.

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials used for authentication. This can be any class that includes and implements Aws::CredentialProvider, or instance of any one of the following classes:

    • Aws::Credentials - Used for configuring static, non-refreshing credentials.

    • Aws::SharedCredentials - Used for loading static credentials from a shared file, such as ~/.aws/config.

    • Aws::AssumeRoleCredentials - Used when you need to assume a role.

    • Aws::AssumeRoleWebIdentityCredentials - Used when you need to assume a role after providing credentials via the web.

    • Aws::SSOCredentials - Used for loading credentials from AWS SSO using an access token generated from aws login.

    • Aws::ProcessCredentials - Used for loading credentials from a process that outputs to stdout.

    • Aws::InstanceProfileCredentials - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • Aws::ECSCredentials - Used for loading credentials from instances running in ECS.

    • Aws::CognitoIdentityCredentials - Used for loading credentials from the Cognito Identity service.

    When :credentials are not configured directly, the following locations will be searched for credentials:

    • Aws.config[:credentials]

    • The :access_key_id, :secret_access_key, :session_token, and :account_id options.

    • ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY'], ENV['AWS_SESSION_TOKEN'], and ENV['AWS_ACCOUNT_ID'].

    • ~/.aws/credentials

    • ~/.aws/config

    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of Aws::InstanceProfileCredentials or Aws::ECSCredentials to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV['AWS_EC2_METADATA_DISABLED'] to true.

  • :region (required, String) —

    The AWS region to connect to. The configured :region is used to determine the service :endpoint. When not passed, a default :region is searched for in the following locations:

#describe_voices(params = {}) ⇒ Types::DescribeVoicesOutput

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.

Examples:

Example: To describe available voices


# Returns the list of voices that are available for use when requesting speech synthesis. Displayed languages are those
# within the specified language code. If no language code is specified, voices for all available languages are displayed.

resp = client.describe_voices({
  language_code: "en-GB", 
})

resp.to_h outputs the following:
{
  voices: [
    {
      gender: "Female", 
      id: "Emma",

#put_lexicon(params = {}) ⇒ Struct

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.

Examples:

Example: To save a lexicon


# Stores a pronunciation lexicon in an AWS Region.

resp = client.put_lexicon({
  content: "<Lexicon Content>", 
  name: "W3C", 
})

resp.to_h outputs the following:
{
}

Request syntax with placeholder values


resp = client.put_lexicon({
  name: "LexiconName", # required
  content: "LexiconContent", # required
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :name (required, 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 (required, String) —

    Content of the PLS lexicon as string data.

Returns:

  • (Struct) —

    Returns an empty response.

#start_speech_synthesis_task(params = {}) ⇒ Types::StartSpeechSynthesisTaskOutput

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.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :engine (String) —

    Specifies the engine (standard, neural, long-form or generative) for Amazon Polly to use when processing input text for speech synthesis. Using a voice that is not supported for the engine selected will result in an error.

  • :language_code (String) —

    Optional language code for the Speech Synthesis 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.

  • :lexicon_names (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.

  • :output_format (required, String) —

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

  • :output_s3_bucket_name (required, String) —

    Amazon S3 bucket name to which the output file will be saved.

  • :output_s3_key_prefix (String) —

    The Amazon S3 key prefix for the output speech file.

  • :sample_rate (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". The default value for long-form voices is "24000". The default value for generative voices is "24000".

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

    Valid value for ogg_opus is "48000".

    Valid value for mu-law and a-law is "8000".

  • :sns_topic_arn (String) —

    ARN for the SNS topic optionally used for providing status notification for a speech synthesis task.

  • :speech_mark_types (Array<String>) —

    The type of speech marks returned for the input text.

  • :text (required, String) —

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

  • :text_type (String) —

    Specifies whether the input text is plain text or SSML. The default value is plain text.

  • :voice_id (required, String) —

    Voice ID to use for the synthesis.

Returns:

    Specifies the engine (standard, neural, long-form, or generative) for Amazon Polly to use when processing input text for speech synthesis. Provide an engine that is supported by the voice you select. If you don't provide an engine, the standard engine is selected by default. If a chosen voice isn't supported by the standard engine, this will result in an error. For information on Amazon Polly voices and which voices are available for each engine, see Available Voices.

  • :language_code (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.

  • :lexicon_names (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.

  • :output_format (required, String) —

    The format in which the returned output will be encoded. For audio stream, this will be mp3, ogg_vorbis, ogg_opus, mu-law, a-law 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.

  • :sample_rate (String) —

    The audio frequency specified in Hz.

    The valid values for mp3 and ogg_vorbis are "8000", "16000", "22050", "24000", "44100" and "48000". The default value for standard voices is "22050". The default value for neural voices is "24000". The default value for long-form voices is "24000". The default value for generative voices is "24000".

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

    Valid value for ogg_opus is "48000".

    Valid value for mu-law and a-law is "8000".

  • :speech_mark_types (Array<String>) —

    The type of speech marks returned for the input text.

  • :text (required, String) —

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

  • :text_type (String) —

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

  • :voice_id (required, String) —

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