Getting Started with Amazon Polly

By -
Amazon Polly is a service that turns text into lifelike speech. Using Amazon Polly, developers can create applications that talk or help developers build entirely new categories of speech-enabled products. Polly allows for configuring Lifelike male or female voices - including bilingual voices that can switch between languages.
Some key features of Amazon Polly include:

- Lifelike Voices - Amazon Polly offers dozens of lifelike voices across a variety of languages and variants. This includes Male and Female voices in US English and other languages. Developers can choose the voice that best fits their needs.

- Text to Speech - Developers can input raw text or SSML into the Polly API and generate high-quality audio files. This allows building apps or services that speak to users. Text can also be synthesized and streamed directly to speakers without the need for storing audio files. 

- Customization - Text can be customized using SSML for controlling output like voice, speech rate, pitch and more. Voices can also be tailored using voice IDs for variants within a language. This allows matching voices to different types of content.

- Usage Flexibility - Audio streams are generated on-demand and don't need to be stored. Audio files like MP3 are also returned for offline usage. This flexibility suits many contexts from streaming playback to downloaded content.

- Low Latency- Polly provides near real-time processing with latency averaging under 100ms. This enables building conversational interfaces and real-time speech applications.

- SDKs & Integration - SDKs are available for popular languages/platforms like Java, Python, .NET, JavaScript and Mobile platforms. APIs also integrate with services like Lex, Rekognition and Amazon CloudFront for building complete solutions.

That covers some of the key features of Amazon Polly.

Amazon Athena is an interactive query service that makes it easy to analyze data directly in Amazon S3 using standard SQL. Athena is serverless, so there is no infrastructure to manage, and you pay only for the queries that you run. With Athena, data analysts, scientists, and developers can directly query datasets stored in Amazon S3 to gain insights without having to load the data into databases or maintain databases. Athena allows you to analyze large datasets in Amazon S3 using standard SQL. With just a few clicks in the AWS Management Console, you can point Athena at your data stored in S3 buckets and start querying it using standard SQL. You don't need to set up any infrastructure or load your data into databases. You pay per query with no setup costs. Athena scales automatically—running queries on petabytes of data is as easy as querying gigabytes of data. It's even integrated with business intelligence (BI) tools like Tableau, QuickSight, and Microsoft Power...

AWS Config provides a detailed view of the configuration of AWS resources in your AWS account. It allows you to view configuration history, detect unauthorized configuration changes, and evaluate your resources' compliance against rules and best practices. AWS Config continuously monitors and records configuration changes to your AWS resources. This allows you to understand their relationships and how they are configured over time.  With AWS Config, you can enable recording of configuration changes for supported resource types like EC2 instances, S3 buckets, Lambda functions, and more. It will build a configuration history for each of your resources. You can then write rules to evaluate if a resource is compliant or non-compliant based on certain configurations. For example, you could write a rule to detect if a S3 bucket doesn't have versioning enabled. AWS Config will then evaluate all your S3 buckets and report any that don't meet the requirement. Some key b...

IAM allows you to control who in your organization has access to which AWS services and resources. IAM is a feature of AWS that allows you to create users and groups within your AWS account, assign permissions to those users and groups, and use credentials to allow and deny access to resources like EC2 instances, S3 buckets, Lambda functions and more. With IAM you can centrally manage users, security credentials like access keys, and permissions to help ensure secure access to AWS resources.  When you first create an AWS account, you begin with a single sign-in identity that has complete access to all AWS services and resources in the account. Using IAM, you can add additional users to your AWS account, without having to ...
