|
# This script is designed to send a request to Amazon's AWS Polly Text-to-Speech
|
|
# service and receive back a PCM audio file(8k, 16bit, mono). Then add a WAV
|
|
# file header to it so it can be played natively in Asterisk.
|
|
#
|
|
# !!! THE AWS PHP SDK IS REQUIRED!!! You can download it here:
|
|
# http://docs.aws.amazon.com/aws-sdk-php/v3/download/aws.zip
|
|
# (the above zip file contains over 3,000 files, make sure you have space)
|
|
# (unzip it inside a new 'polly' directory in the 'agc' web directory)
|
|
#
|
|
# !!! IMPORTANT !!! You must customize this script to your needs, and you must
|
|
# populate the credentials and region for your AWS account
|
|
#
|
|
# !!! IMPORTANT !!! This script assumes that the directory exists and is writable:
|
|
# agc/polly/generated
|
|
#
|
|
### Example URL to use in a SCRIPT tab Iframe:
