Exemplos do Amazon Polly usando AWS SDK for .NET
Os exemplos de código a seguir mostram como realizar ações e implementar cenários comuns usando o AWS SDK for .NET com o Amazon Polly.
Ações são trechos de código de programas maiores e devem ser executadas em contexto. Embora as ações mostrem como chamar funções de serviço específicas, é possível ver as ações contextualizadas em seus devidos cenários e exemplos entre serviços.
Cenários são exemplos de código que mostram como realizar uma tarefa específica chamando várias funções dentro do mesmo serviço.
Cada exemplo inclui um link para GitHub, onde você pode encontrar instruções sobre como configurar e executar o código no contexto.
