AWSPollySynthesizeSpeechInput Class Reference
|Inherits from||AWSRequest : AWSModel : AWSMTLModel|
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.
@property (nonatomic, assign) AWSPollyLanguageCode 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.
@property (nonatomic, strong) NSArray<NSString*> *lexiconNames
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.
