AWSPollySynthesisTask

@interface AWSPollySynthesisTask

SynthesisTask object that provides information about a speech synthesis task.

  • Timestamp for the time the synthesis task was started.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSDate *_Nullable creationTime;

    Swift

    var creationTime: Date? { get set }
  • 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.

    Declaration

    Objective-C

    @property (nonatomic) AWSPollyEngine engine;

    Swift

    var engine: AWSPollyEngine { get set }
  • Optional language code for a synthesis task. 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.

    Declaration

    Objective-C

    @property (nonatomic) AWSPollyLanguageCode languageCode;

    Swift

    var languageCode: AWSPollyLanguageCode { get set }
  • 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.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSArray<NSString *> *_Nullable lexiconNames;

    Swift

    var lexiconNames: [String]? { get set }
  • 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.

    Declaration

    Objective-C

    @property (nonatomic) AWSPollyOutputFormat outputFormat;

    Swift

    var outputFormat: AWSPollyOutputFormat { get set }
  • Pathway for the output speech file.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable outputUri;

    Swift

    var outputUri: String? { get set }
  • Number of billable characters synthesized.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable requestCharacters;

    Swift

    var requestCharacters: NSNumber? { get set }
  • 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”.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable sampleRate;

    Swift

    var sampleRate: String? { get set }
  • ARN for the SNS topic optionally used for providing status notification for a speech synthesis task.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable snsTopicArn;

    Swift

    var snsTopicArn: String? { get set }
  • The type of speech marks returned for the input text.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSArray<NSString *> *_Nullable speechMarkTypes;

    Swift

    var speechMarkTypes: [String]? { get set }
  • The Amazon Polly generated identifier for a speech synthesis task.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable taskId;

    Swift

    var taskId: String? { get set }
  • Current status of the individual speech synthesis task.

    Declaration

    Objective-C

    @property (nonatomic) AWSPollyTaskStatus taskStatus;

    Swift

    var taskStatus: AWSPollyTaskStatus { get set }
  • Reason for the current status of a specific speech synthesis task, including errors if the task has failed.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable taskStatusReason;

    Swift

    var taskStatusReason: String? { get set }
  • Specifies whether the input text is plain text or SSML. The default value is plain text.

    Declaration

    Objective-C

    @property (nonatomic) AWSPollyTextType textType;

    Swift

    var textType: AWSPollyTextType { get set }
  • Voice ID to use for the synthesis.

    Declaration

    Objective-C

    @property (nonatomic) AWSPollyVoiceId voiceId;

    Swift

    var voiceId: AWSPollyVoiceId { get set }
