1. Setting Up Amazon Polly

1.1 Create and Configure Your AWS Account

Visit the AWS Management Console and sign in—or create—a free AWS account.
Navigate to the Amazon Polly service under “Machine Learning”.
Ensure you configure IAM permissions so Polly can be accessed via console and programmatically.
Verify that you are within the free tier: 5 M characters/month for Standard voices and 1 M characters/month for NTTS voices for the first 12 months.

1.2 Understanding Pricing and Limits

Amazon Polly uses a pay-as-you-go model: Standard voices cost $4.00 / 1 M characters; NTTS voices cost $16.00 / 1 M characters beyond the free tier.
You can cache and replay generated speech at no extra charge, reducing repeated costs for frequently used text.
Monitoring your usage in the AWS Billing dashboard helps you avoid unexpected charges.

2. Generating Speech via Console

2.1 Console Demo Walkthrough

In the Amazon Polly console, click “Text-to-Speech” demo.
Enter your text or SSML in the provided editor.
Select a voice: choose from Standard, NTTS, or Newscaster styles for enhanced naturalness.
Click “Listen” to preview; click “Download as MP3” to save your file.

2.2 Crafting SSML for Nuance

Use SSML tags to fine-tune speech:

<speak>
  Hello, <break time="500ms"/> welcome to Amazon Polly.
  <prosody rate="90%" pitch="+2st">Enjoy</prosody> lifelike speech.
</speak>

<break> controls pausing.
<prosody> adjusts speed and pitch.
<emphasis> can highlight key phrases.

3. Integrating via API

3.1 Calling the Polly API with AWS SDK

In Python, install the SDK:

pip install boto3

Then use:

mport boto3

polly = boto3.client('polly')
response = polly.synthesize_speech(
    Text='Generate life-like speech with Amazon Polly.',
    TextType='text',
    VoiceId='Joanna',
    OutputFormat='mp3'
)
with open('speech.mp3', 'wb') as f:
    f.write(response['AudioStream'].read())

This code demonstrates how to Generate LifeLike Speech with Amazon Polly programmatically.

3.2 Streaming and Speech Marks

Amazon Polly can return Speech Marks metadata—timing information for words and sentences—enabling karaoke-style highlighting or lip-syncing.
Use:

SpeechMarkTypes=['sentence','word']

in your request to receive JSON metadata alongside audio.

4. Advanced Customization

4.1 Custom Lexicons and Brand Voices

Upload a custom lexicon (XML) to modify pronunciations for product names or acronyms.
For enterprise clients, Brand Voice creation offers a unique, on-brand neural voice built in collaboration with AWS experts.

4.2 Time-Driven Prosody for Localization

Use SSML’s

<amazon:effect name="drc">

or set

maxDuration

with prosody attributes to ensure translated speech fits original video timings—ideal for localized dubbing.

4.3 Multi-Language and Style Switching

Dynamically switch voices and languages mid-stream for multilingual applications by chaining SSML <lang> tags.
