📋 Setup Process (Production Ready)

Step 1: Create AWS Account

  1. Sign Up: Visit aws.amazon.com
  2. Account Setup: Complete registration with credit card
  3. Console Access: Log into AWS Management Console
  4. Billing: Set up billing alerts and budgets

Step 2: Create IAM User for Polly

  1. IAM Console: Navigate to IAM in AWS Console
  2. Create User:
    • Username: textto-speech-generator
    • Access type: Programmatic access
  3. Attach Policy:
    • Search for AmazonPollyFullAccess
    • Attach the policy to user
  4. Download Credentials:
    • Navigate into the user, select Security credentials tab, and click Create access key
    • Choose CLI/Console, tick accept and click finish.
    • On the final page, save the Access Key and Secret Access Key.

Step 3: Configure TextToSpeech Generator

API Configuration: Two Secure Methods

All providers in TextToSpeech Generator support two secure ways to supply credentials and configuration:

1. Configuration File/GUI (Default):

  • Enter your Access Key, Secret Key, and Region in the GUI or JSON config file.

2. Environment Variables (Recommended for Testing/Security):

Required Environment Variables

Variable Description
AWS_POLLY_ACCESS_KEY Your AWS access key
AWS_POLLY_SECRET_KEY Your AWS secret key
AWS_POLLY_REGION The AWS region (e.g. eu-west-2)
AWS_POLLY_VOICE The AWS Polly voice (e.g. Joanna)

Example (PowerShell):

$env:AWS_POLLY_ACCESS_KEY = 'your-access-key'
$env:AWS_POLLY_SECRET_KEY = 'your-secret-key'
$env:AWS_POLLY_REGION     = 'eu-west-2'
$env:AWS_POLLY_VOICE      = 'Joanna'

Important:

  • Your access/secret keys and region must match your AWS account.
  • You must select a valid Polly voice or TTS generation will fail.
  • Region: Choose AWS region (us-east-1, us-west-2, eu-west-1)
  1. Select Voice: Choose from available voices

✅ Production Implementation Status

Full AWS Polly Integration

The application now has complete AWS Polly integration with real audio synthesis:

# Production function generates real audio files
function Invoke-PollyTTS {
    # Full AWS Polly API implementation
    # Creates actual MP3/WAV audio files using AWS Polly service
    
    $audioData = Invoke-RestMethod -Uri $pollyEndpoint -Method POST -Body $requestBody -Headers $headers
    [System.IO.File]::WriteAllBytes($OutputPath, $audioData)
    
    return @{ Success = $true; Message = "Generated successfully"; FileSize = $audioData.Length }
}

Result: Files are created as actual audio with high-quality AWS Polly speech synthesis.
