Polly

Client

class Polly.Client

A low-level client representing Amazon Polly:

client = session.create_client('polly')

These are the available methods:

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
delete_lexicon(**kwargs)

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 .

See also: AWS API Documentation

Request Syntax

response = client.delete_lexicon(
    Name='string'
)
Parameters
Name (string) --

[REQUIRED]

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

Return type

Examples

Deletes a specified pronunciation lexicon stored in an AWS Region.

response = client.delete_lexicon(
    Name='example',
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
describe_voices(**kwargs)

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
  • Engine (string) -- Specifies the engine (standard or neural ) used by Amazon Polly when processing input text for speech synthesis.
  • LanguageCode (string) -- The language identification tag (ISO 639 code for the language name-ISO 3166 country code) for filtering the list of voices returned. If you don't specify this optional parameter, all available voices are returned.
  • IncludeAdditionalLanguageCodes (boolean) -- Boolean value indicating whether to return any bilingual voices that use the specified language as an additional language. For instance, if you request all languages that use US English (es-US), and there is an Italian voice that speaks both Italian (it-IT) and US English, that voice will be included if you specify yes but not if you specify no .

        Optional language code for a synthesis task. 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 will use 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.

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.

Exceptions

put_lexicon(**kwargs)

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 .

start_speech_synthesis_task(**kwargs)

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.

Response Structure

  • (dict) --

    • SynthesisTasks (list) --

      List of SynthesisTask objects that provides information from the specified task in the list request, including output format, creation time, task status, and so on.

      • (dict) --

        SynthesisTask object that provides information about a speech synthesis task.

        • Engine (string) --

          Specifies the engine (standard or neural ) 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.

        • TaskId (string) --

          The Amazon Polly generated identifier for a speech synthesis task.

        • TaskStatus (string) --

          Current status of the individual speech synthesis task.

        • TaskStatusReason (string) --

          Reason for the current status of a specific speech synthesis task, including errors if the task has failed.

        • OutputUri (string) --

          Pathway for the output speech file.

        • CreationTime (datetime) --

          Timestamp for the time the synthesis task was started.

        • RequestCharacters (integer) --

          Number of billable characters synthesized.

        • SnsTopicArn (string) --

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

        • LexiconNames (list) --

          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.

          • (string) --
        • 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.

        • 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 (list) --

          The type of speech marks returned for the input text.

          • (string) --
        • TextType (string) --

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

        • VoiceId (string) --

          Voice ID to use for the synthesis.

        • LanguageCode (string) --

          Optional language code for a synthesis task. 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 will use 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.
