Polly.Client¶A low-level client representing Amazon Polly:
client = session.create_client('polly')
These are the available methods:
can_paginate()delete_lexicon()describe_voices()generate_presigned_url()get_lexicon()get_paginator()get_waiter()list_lexicons()put_lexicon()synthesize_speech()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: | dict |
| Returns: | Response Syntax{}
Response Structure
|
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.

get_paginator(operation_name)¶Create a paginator for an operation.

check if an operation is pageable. |
| Return type: | L{botocore.paginate.Paginator} |
| Returns: | A paginator object. |

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.

synthesize_speech(**kwargs)¶Synthesizes UTF-8 input, plain text or SSML, to a stream of bytes. SSML input must be valid, well-formed SSML.
