describe-voices

Description

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.

See ‘aws help’ for descriptions of global parameters.

describe-voices is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Voices

Options

--engine (string)

Specifies the engine (standard or neural ) used by Amazon Polly when processing input text for speech synthesis.

Possible values:

• standard

• neural

--language-code (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.

Possible values:

• arb

• cmn-CN

• cy-GB

• da-DK

• de-DE

• en-AU

• en-GB

• en-GB-WLS

• en-IN

• en-US

• es-ES

• es-MX

• es-US

• fr-CA

• fr-FR

• is-IS

• it-IT

• ja-JP

• hi-IN

• ko-KR

• nb-NO

• nl-NL

• pl-PL

• pt-BR

• pt-PT

• ro-RO

• ru-RU

• sv-SE

• tr-TR

--include-additional-language-codes | --no-include-additional-language-codes (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 .

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Output

Voices -> (list)

A list of voices with their properties.

(structure)

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 .

(string)

SupportedEngines -> (list)

Specifies which engines (standard or neural ) that are supported by a given voice.

(string)

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.
