2024/02/15 - Amazon Polly - 5 updated api methods
Changes Amazon Polly adds 1 new voice - Burcu (tr-TR)
{'Voices': {'Id': {'Burcu'}}}
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.

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 .

(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.

{'VoiceId': {'Burcu'}}
Response {'SynthesisTask': {'VoiceId': {'Burcu'}}}
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.

)
string
Specifies the engine (standard , neural or long-form ) for Amazon Polly to use when processing input text for speech synthesis. For information on Amazon Polly voices and which voices are available for each engine, 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.
long-form-only voices
When using long-form-only voices such as Danielle (en-US), this parameter is required and must be set to long-form . If the engine is not specified, or is set to standard or neural , this will result in an error.
Type: String
Valid Values: standard | neural | long-form
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.
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.
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. For information about storing lexicons, see PutLexicon .
(string) --
string
[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.
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".
Valid values for pcm are "8000" and "16000" The default value is "16000".
list
The type of speech marks returned for the input text.
(string) --
string
[REQUIRED]
Input text to synthesize. If you specify ssml as the TextType , follow the SSML format for the input text.
string
Specifies whether the input text is plain text or SSML. The default value is plain text. For more information, see Using SSML .
string
[REQUIRED]
Voice ID to use for the synthesis. You can get a list of available voice IDs by calling the DescribeVoices operation.

Response Syntax
{
'AudioStream': StreamingBody(),
'ContentType': 'string',

}
Response Structure
(dict) --
AudioStream (:class:`.StreamingBody`) --
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 application/x-json-stream.
RequestCharacters (integer) --
Number of characters synthesized.
