Connect SignalWire to Smallest AI Voice Models

Use Lightning text-to-speech as a built-in voice in SignalWire's SWML AI agents. Pick a Smallest AI voice right in your script, with no bridging server to run.

OVERVIEW

Lightning voices, native to SignalWire.

SignalWire is a communications platform for building programmable voice, and Smallest AI is available natively inside it as one of its built-in text-to-speech engines. Unlike a custom telephony bridge, there is no server to run and no audio to stream manually. You select a Smallest AI voice directly in your SWML script, and SignalWire's AI Agent handles the rest. You set the voice field in your script's languages section to a Smallest AI voice string, choosing from the Lightning v3.1 standard pool or the Lightning v3.1 Pro premium catalog. Assign the script to a phone number, call it, and your agent answers in a Smallest AI voice.
