Overview

Aircall gives sales and support teams a cloud phone system; Resemble AI gives it a voice. Swap default TTS for a branded, human-sounding voice across every Aircall IVR menu, outbound campaign, and voicemail drop with sub-second streaming so nothing feels pre-recorded.

Inbound calls can also route through Resemble Detect to flag AI-cloned voices in real time, protecting sales reps and finance teams from voice-spoofing fraud before the call connects.

Features

Branded cloud phone voice

Clone your founder, best rep, or brand voice and deploy it across every Aircall IVR menu, greeting, and automated prompt.

Dynamic outbound campaigns

Personalize outbound call scripts with the prospect's name and context, generated on the fly with sub-second latency.

Inbound deepfake detection

Resemble Detect scans inbound audio to flag cloned voices used in vishing, executive impersonation, or account-takeover attempts.

Multilingual call flows

Support customers across 90+ languages using one cloned voice profile. Localize without hiring per-region voice talent.

Smooth rep handoffs

Clone your team's voices so AI-to-human transitions on Aircall feel continuous instead of jarring the caller with a voice change.

Compliance-ready

HIPAA and GDPR compliant and SOC 2 Type II in progress for audio processing. Suitable for regulated sales and support workflows.
