SynthesizeSpeechInput

public struct SynthesizeSpeechInput : AWSShape

Undocumented

  • Declaration

    Swift

    public static var _members: [AWSShapeMember]

  • 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

    Swift

    public let engine: Engine?

  • Optional language code for the Synthesize Speech 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.

    Declaration

    Swift

    public let languageCode: LanguageCode?

  • 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. For information about storing lexicons, see PutLexicon.

    Declaration

    Swift

    public let lexiconNames: [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. When pcm is used, the content returned is audio/pcm in a signed 16-bit, 1 channel (mono), little-endian format.

    Declaration

    Swift

    public let outputFormat: OutputFormat

  • 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

    Swift

    public let sampleRate: String?

  • The type of speech marks returned for the input text.

    Declaration

    Swift

    public let speechMarkTypes: [SpeechMarkType]?

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

    Declaration

    Swift

    public let text: String

  • Specifies whether the input text is plain text or SSML. The default value is plain text. For more information, see Using SSML.

    Declaration

    Swift

    public let textType: TextType?

  • Voice ID to use for the synthesis. You can get a list of available voice IDs by calling the DescribeVoices operation.

    Declaration

    Swift

    public let voiceId: VoiceId
