Overview

Resemble AI plugs into Character.AI to turn text-based personas into fully voiced companions. With 44kHz sample rate output and sub-second streaming latency, custom character voices feel immersive in group chats, interactive fiction, and community-built worlds — no more text-only roleplay.

Creators can clone the voices of original characters (with consent) or assemble personalities from Resemble's voice library, then control delivery programmatically through our API. The integration also pairs with Resemble Detect and PerTh watermarking to protect cloned voices from misuse across the platform.

Features

Custom character voices

Clone a voice from a short sample or build one from scratch. Every AI companion gets a unique, identifiable voice to match its personality.

Low-latency streaming TTS

Stream speech in under 500ms so group chats feel conversational. No pre-rendering, no awkward pauses between turns.

Deepfake protection

Resemble Detect and PerTh watermarking guard cloned character voices against unauthorized reuse or impersonation elsewhere on the internet.

Multilingual voices

Localize characters across 90+ languages with consistent personality. Same companion, same voice, any language the user prefers.

Emotion and style control

Direct each line with emotional cues — happy, angry, whispered, excited — so AI companions react in-scene instead of reading flat.

Consent-first cloning

Voice creation requires explicit consent from the source speaker. Every cloned voice is watermarked and traceable back to its owner.

Use cases

  • Voice AI companions in Character.AI group chats so conversations play back as audio, not text
  • Clone celebrity or fictional character voices (with rights) for fan-built interactive stories
  • Localize popular characters into 90+ languages without re-recording voice talent per region
  • Give original user-made characters a consistent, recognizable voice across every session
  • Watermark cloned voices with PerTh so misuse outside the platform can be traced
  • Power roleplay and interactive fiction experiences with emotion-aware line delivery
