How to Convert Text to Speech in PowerShell with AWS Polly

Amazon's Polly service is a great way to convert text into speech through an automated process. Polly can be used for all sorts of things like enabling access features on websites or apps. Though text files can be converted to audio through Polly's AWS dashboard, it would be convenient to convert text files programmatically instead. This process can be done through various programming languages and command-line environments, but PowerShell is especially suited for this task due to how it manages data differently than other CLIs like Bash.

PowerShell treats data as objects instead of strings. This is perfect for the AWS SDK since most commands typically require some form of a data object to work properly. Polly is no different.

To call Polly through PowerShell, first, make sure you have the AWS Tools for PowerShell cmdlets installed. Once those are installed, use the Get-POLSpeech cmdlet.

The Get-POLSpeech cmdlet includes 11 additional flags:

• Text

• Engine

• LanguageCode

• LexiconName <String[]>

• OutputFormat

• SampleRate

• SpeechMarkType <String[]>

• TextType

• VoiceId

• Select

• PassThru

Note that the Text, OutputFormat, and VoiceID flags are required. The others are optional. You can find the VoiceID from the Polly Dashboard within your AWS account.
