# Exemplos de código para o Amazon Polly usando AWS SDKs
Os exemplos de código a seguir mostram como usar o Amazon Polly com um kit de desenvolvimento de AWS software (SDK).
*Ações* são trechos de código de programas maiores e devem ser executadas em contexto. Embora as ações mostrem como chamar perfis de serviço individuais, você pode ver as ações no contexto em seus cenários relacionados.
*Cenários* são exemplos de código que mostram como realizar tarefas específicas chamando várias funções dentro de um serviço ou combinadas com outros Serviços da AWS.

Mostra como usar o Amazon Polly e o Tkinter para criar um aplicativo de sincronização labial que exibe um rosto animado falando junto com a fala sintetizada pelo Amazon Polly. A sincronização labial é realizada solicitando uma lista de fonemas do Amazon Polly que correspondam à fala sintetizada.
+ Obter metadados de voz do Amazon Polly e exibi-os em um aplicativo Tkinter.
+ Obter áudio de fala sintetizado e respectivas marcas de fala de fonema do Amazon Polly.
+ Reproduzir o áudio com movimentos sincronizados da boca em um rosto animado.
+ Enviar tarefas de síntese assíncrona para textos longos e recuperar a saída de um bucket do Amazon Simple Storage Service (Amazon S3).

# Criar uma aplicação que analise o feedback dos clientes e sintetize o áudio
Os exemplos de código a seguir mostram como criar uma aplicação que analisa os cartões de comentários dos clientes, os traduz do idioma original, determina seus sentimentos e gera um arquivo de áudio do texto traduzido.
------
#### [ .NET ]
**SDK para .NET**
Esta aplicação de exemplo analisa e armazena cartões de feedback de clientes. Especificamente, ela atende à necessidade de um hotel fictício na cidade de Nova York. O hotel recebe feedback dos hóspedes em vários idiomas na forma de cartões de comentários físicos. Esse feedback é enviado para a aplicação por meio de um cliente web. Depois de fazer upload da imagem de um cartão de comentário, ocorrem as seguintes etapas:
+ O texto é extraído da imagem usando o Amazon Textract.
+ O Amazon Comprehend determina o sentimento do texto extraído e o idioma.
+ O texto extraído é traduzido para o inglês com o Amazon Translate.
+ O Amazon Polly sintetiza um arquivo de áudio do texto extraído.
A aplicação completa pode ser implantada com o AWS CDK. Para obter o código-fonte e as instruções de implantação, consulte o projeto em [ GitHub](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/dotnetv3/cross-service/FeedbackSentimentAnalyzer).
