Synthesia

Pair Resemble's custom AI voices with Synthesia's AI avatars to produce video content that sounds as personal as it looks — across 90+ languages and every brand persona.

Overview

Synthesia generates AI avatar videos from text. Resemble AI replaces the default voiceovers with custom-cloned voices that match your brand, your spokesperson, or any talent you've licensed — so every video feels like it was recorded by a real person, not stitched together from stock voices.

Once connected, Resemble voices flow directly into Synthesia's avatar rendering pipeline. Localize training videos, marketing explainers, and internal comms across dozens of languages without re-recording, and keep voice consistency across every asset your team ships.

Features

Custom AI voice cloning

Clone a brand voice or a real spokesperson and use it for every Synthesia avatar video — no studio, no voice actor booking.

Multilingual localization

Generate the same video in 90+ languages using one cloned voice. Perfect for global training rollouts and marketing campaigns.

Emotion and style control

Direct tone per scene — confident for product demos, warm for onboarding, urgent for alerts without re-recording.

PerTh watermarking

Every Resemble-generated voice carries an inaudible neural watermark, so you can verify authenticity if a video is repurposed or leaked.

Voice management API

Manage voice libraries, permissions, and approved speakers centrally. Lock specific voices to specific Synthesia projects.

Enterprise compliance

SOC 2 Type II (in progress), HIPAA, and GDPR ready. Safe for regulated industries producing internal training or customer-facing video.
