start-speech-synthesis-task

Description

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.

Options

--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.

Possible values:

• standard

• neural

--language-code (string)

Optional language code for the Speech Synthesis 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.

Possible values:

• arb

• cmn-CN

• cy-GB

• da-DK

• de-DE

• en-AU

• en-GB

• en-GB-WLS

• en-IN

• en-US

• es-ES

• nb-NO

• nl-NL

• pl-PL

• pt-BR

• pt-PT

• ro-RO

• ru-RU

• sv-SE

• tr-TR

--lexicon-names (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)

Syntax:

"string" "string" ...

--output-format (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.

Possible values:

• json

• mp3

• ogg_vorbis

• pcm

--output-s3-bucket-name (string)

Amazon S3 bucket name to which the output file will be saved.

--output-s3-key-prefix (string)

The Amazon S3 key prefix for the output speech file.

--sample-rate (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”.

--sns-topic-arn (string)

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

--speech-mark-types (list)

The type of speech marks returned for the input text.

(string)

Syntax:

"string" "string" ...

Where valid values are:
  sentence
  ssml
  viseme
  word

--text (string)

The input text to synthesize. If you specify ssml as the TextType, follow the SSML format for the input text.

--text-type (string)

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

Possible values:

• ssml

• text

--voice-id (string)

Voice ID to use for the synthesis.

Possible values:

• Aditi

• Amy

• Astrid

• Bianca

• Brian

• Camila

--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.

--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.
