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.

(dict) --
Voices (list) --
A list of voices with their properties.
(dict) --

Gender (string) --
Gender of the voice.
Id (string) --
Amazon Polly assigned voice ID. This is the ID that you specify when calling the SynthesizeSpeech operation.
LanguageCode (string) --
Language code of the voice.
LanguageName (string) --
Human readable name of the language in English.
Name (string) --
Name of the voice (for example, Salli, Kendra, etc.). This provides a human readable voice name that you might display in your application.

NextToken (string) --
The pagination token to use in the next request to continue the listing of voices. NextToken is returned only if the response is truncated.

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 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.
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 .

)
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 .
[REQUIRED]
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.
The audio frequency specified in Hz.
The valid values for mp3 and ogg_vorbis are "8000", "16000", and "22050". The default value is "22050".
Valid values for pcm are "8000" and "16000" The default value is "16000".
The type of speech marks returned for the input text.
[REQUIRED]
Input text to synthesize. If you specify ssml as the TextType , follow the SSML format for the input text.
[REQUIRED]
Voice ID to use for the synthesis. You can get a list of available voice IDs by calling the DescribeVoices operation.
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 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.

Response Structure
(dict) --
AudioStream (StreamingBody) --
Stream containing the synthesized speech.
ContentType (string) --
Specifies the type audio stream. This should reflect the OutputFormat parameter in your request.
RequestCharacters (integer) --
Number of characters synthesized.
Examples
Synthesizes plain text or SSML into a file of human-like speech.

Text='All Gaul is divided into three parts',

The available paginators are:
paginator = client.get_paginator('describe_voices')
Creates an iterator that will paginate through responses from Polly.Client.describe_voices().

The total number of items to return. If the total number of items available is more than the value specified in max-items then a NextToken will be provided in the output that you can use to resume pagination.
The size of each page.
A token to specify where to start paginating. This is the NextToken from a previous response.

Response Structure
(dict) --
Voices (list) --
A list of voices with their properties.
(dict) --
Description of the voice.
Gender (string) --
Gender of the voice.
Id (string) --
Amazon Polly assigned voice ID. This is the ID that you specify when calling the SynthesizeSpeech operation.
LanguageCode (string) --
Language code of the voice.
LanguageName (string) --
Human readable name of the language in English.
Name (string) --
Name of the voice (for example, Salli, Kendra, etc.). This provides a human readable voice name that you might display in your application.
AdditionalLanguageCodes (list) --
Additional codes for languages available for the specified voice in addition to its default language.
For example, the default language for Aditi is Indian English (en-IN) because it was first used for that language. Since Aditi is bilingual and fluent in both Indian English and Hindi, this parameter would show the code hi-IN .
