QuickGuide: Use AWS Polly on Windows 10 to synthesize speech from text

Step 1 – Install Python on Windows laptop/desktop

1. Open cmd and type python3 and press enter
2. If you don’t have Python installed already, it will take you to Windows Store, click on Get
3. Prep for Polly execution

pip3 install boto3 
pip3 install --upgrade awscli

Step 2 – Create dummy polly.py

import boto3

polly_client = boto3.Session(
                aws_access_key_id=‘<access key>',                     
    aws_secret_access_key=<secret access key>',
    region_name='us-east-2').client('polly')

response = polly_client.synthesize_speech(VoiceId='Joanna',
                OutputFormat='mp3', 
                Text = 'This is a sample text to be synthesized.')

file = open('speech.mp3', 'wb')
file.write(response['AudioStream'].read())
file.close()

Step 3 – Execute polly.py and play speech.mp3

python3 polly.py

Successful execution of the script should create a speech.mp3 file.
