Voice Alarm Script

Is there a way to send a voice message via scripting?

For example, the twilio module provides a scripting function system.twilio.sendSms which allows you to send an SMS message via scripting instead of using the alarm notification pipeline.

Is there any way to do this but it be a voice message instead of an SMS? Different module? etc.

No, this isn’t (currently) possible using any IA module. There might be some way to call into Twilio’s API directly, but even Kymera’s twilio module doesn’t add arbitrary voice commands to my knowledge.
