Resemble AI integrates natively with Twilio's telephony infrastructure, letting you replace robotic TTS with custom AI voices that sound exactly like your brand or a real person. Whether you're building IVR menus, outbound notification systems, or AI-powered phone agents, this integration drops into your existing Twilio setup with no infrastructure changes.
For security-conscious deployments, the integration also supports Resemble Detect our multimodal deepfake detection layer which can flag AI-generated or cloned voices on inbound calls in real time, protecting your agents and customers from voice spoofing fraud.
Clone your brand voice or build a new one. Deliver consistent, human-sounding speech across every call with sub-second latency.
Stream audio directly into Twilio's <Play> and <Say> verbs. No pre-rendered files needed — generate speech dynamically per call.
Run Resemble Detect on inbound audio to identify AI-generated or cloned voices before they reach your agents.
Generate speech across 90+ languages and accents. Localize IVR flows or outbound campaigns without separate voice talent.
Works with both Twilio inbound webhooks and outbound call APIs. Handle any direction of call with the same voice profile.
All audio processing is compliant with healthcare and data privacy requirements. Suitable for regulated industries.
Point your Twilio webhook at Resemble's streaming TTS endpoint and pass the text you want spoken. The integration returns audio Twilio can play directly in a call.
