to enable TTS (text to speech) do the following additional setup steps:
sudo pip3 install boto3
mkdir /var/lib/freeswitch/tts
chown freeswitch:freeswitch /var/lib/freeswitch/tts
cp -r resources/aws_tts/* `python3 -c 'import site; print(site.getsitepackages()[0])'`
chmod +rx /etc/itas/ace
cp resources/aws_tts/aws.ini.example /etc/itas/ace/aws.ini
NOTE: You will also need to add the mod_python3 module to the /etc/freeswitch/autoload_configs/modules.conf.xml file. You can then run the command fs_cli -x 'reload mod_python3'.
Modify /etc/itas/ace/aws.ini and modify the aws_access_key and aws_secret_key parameters with credentials from your AWS instance
To create an AWS access key and secret, log into the AWS administration console and browse to Services >> Security, Identity, & Compliance >> IAM
Next, browse to User Groups then click Create Group.
Create a name for you group, then scroll down to the attach permissions policies section, then in the filter text field enter polly, then press enter. Select the checkbox next to AmazonPollyReadOnlyAccess policy, then click Create Group.
Next, browse to Users then click Add users.
Enter a username to create, check the Access key - Programmatic access checkbox for the credential type, then click Next: Permissions. Select the checkbox next to the group you created previously, then click Next: Tags. Click Next: Review. Finally, click Create User.
Once the user has been created, add the Access key ID and Secret access key to /etc/itas/ace/aws.ini
To test if text to speech is working you can run the following command
fs_cli -x 'python streamtext voice=Joanna|text=This is a test, please disregard'
This command should return the location of a wav file.
