How AI is used
SignalWire is a composable communications platform designed for the development of conversational AI agents. It integrates telephony, SIP, and WebRTC into a single environment, which is intended to reduce the latency often caused by using multiple third-party vendors for speech-to-text and LLM processing.
The tool is primarily for developers and enterprise technical teams building voicebots or AI-driven contact centers. It uses the SignalWire Markup Language (SWML), utilizing YAML or JSON to define call flows, agent behaviors, and tool access.
By combining the media stack with AI capabilities, the platform supports translation in real time, AI vision for video calls and MMS, and serverless functions that allow agents to interact with external APIs. This architecture is designed to support more natural voice interactions.
Buyers should note that this is a technical tool requiring development expertise. Teams should confirm if their technical skills align with the use of markup languages and API integrations required to deploy these agents.
Key Features
SignalWire Markup Language (SWML)
A declarative language using YAML or JSON to orchestrate call flows, configure AI agents, and define conversational logic.
Integrated Voice Pipeline
Designed for 500-900ms round-trip latency by integrating telephony and AI components on a single platform.
SWAIG Serverless Functions
Supports the ability for AI agents to call APIs and access external databases within the call script.
AI Vision
Supports visual input processing for AI agents during video calls and MMS.
Real time Translation
Supports live translation of calls across different languages.
Unified Connectivity
Provides a single platform for connecting agents to phone numbers, SIP addresses, and WebRTC.
Use Cases
Automated Reservation Agents
Building voice agents that can collect customer details and maintain state to remember interactions across multiple calls.
Knowledge-Base Q&A
Deploying RAG-based agents that fetch data from vectorized databases to provide answers to customer queries.
Tool-Enabled Search Bots
Creating AI agents capable of using external tools to retrieve specific data, such as movie or product information.
AI-Powered Video Assistance
Developing video call agents that can interpret visual input and answer questions based on the visual data.
