Container for the parameters to the SynthesizeSpeech operation. Synthesizes UTF-8 input, plain text or SSML, to a stream of bytes. SSML input must be valid, well-formed SSML. Some alphabets might not be available with all the voices (for example, Cyrillic might not be read at all by English voices) unless phoneme mapping is used. For more information, see How it Works.

Engine | Amazon.Polly.Engine |

LanguageCode | Amazon.Polly.LanguageCode |
Gets and sets the property LanguageCode. 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 uses
the default language of the bilingual voice. The default language for any voice is

LexiconNames | System.Collections.Generic.List<System.String> |
Gets and sets the property 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. For information about storing lexicons, see PutLexicon. |
|
OutputFormat | Amazon.Polly.OutputFormat |
Gets and sets the property OutputFormat. 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. |
|
SampleRate | System.String |
Gets and sets the property 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". Valid values for pcm are "8000" and "16000" The default value is "16000". |
