simple example on how to "text-to-speech" with amazon's polly service

aws-polly.py

#!/usr/bin/env python3
from boto3 import client
from contextlib import closing

polly = client("polly", 'us-east-1')

voice = 'Brian'

response = polly.synthesize_speech(
    Text='''Imagine how your bullet points turn into presenter notes!
            And your visuals start to speak for themselves.''',
    OutputFormat="mp3",
    VoiceId=voice)

print(response)

if "AudioStream" in response:
    with closing(response["AudioStream"]) as stream:
        data = stream.read()
        filename = voice + '.mp3'
        fo = open(filename, "bw+")
        fo.write(data)
        fo.close()
