Start Speech Synthesis Task

polly_start_speech_synthesis_task

R Documentation

Allows the creation of an asynchronous synthesis task, by starting a new SpeechSynthesisTask¶

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. The SpeechSynthesisTask object is available for 72 hours after starting the asynchronous synthesis task.

Usage¶

polly_start_speech_synthesis_task(Engine, LanguageCode, LexiconNames,
  OutputFormat, OutputS3BucketName, OutputS3KeyPrefix, SampleRate,
  SnsTopicArn, SpeechMarkTypes, Text, TextType, VoiceId)

Arguments¶

Engine

Specifies the engine (standard, neural, long-form or generative) 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.

LanguageCode

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 uses the default language of the bilingual voice. The default language for any voice is the one returned by the describe_voices operation for the LanguageCode parameter. For example, if no language code is specified, Aditi will use Indian English rather than Hindi.

LexiconNames

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.

OutputFormat

[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.

OutputS3BucketName

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

OutputS3KeyPrefix

The Amazon S3 key prefix for the output speech file.

SampleRate

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". The default value for generative voices is "24000".

Valid values for pcm are "8000" and "16000" The default value is "16000".

SnsTopicArn

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

SpeechMarkTypes

The type of speech marks returned for the input text.

Text

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

TextType

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

VoiceId

[required] Voice ID to use for the synthesis.

Value¶

A list with the following syntax:
