# Alternatives to Resemble AI

Resemble AI provides enterprise voice cloning, real-time TTS, and streaming voice synthesis via API, alongside a deepfake-detection and watermarking product (Detect/Verify) it added as AI voice fraud grew. It's positioned for enterprises needing custom voice cloning plus provenance/consent verification for synthetic audio.

Resemble AI ranks #6 of 10 in AI voice generation, with an Alt Score of 90. It is licensed under MIT, freemium from $350/mo and available on Web and Browser extension. 9 of 9 checklist rows are verified against a public source.

## Overview

- **Who it's for**: Developers and enterprise teams (voice agents, contact centers, media/localization, games, healthcare, and other regulated industries) that need programmatic voice cloning and text-to-speech, plus organizations that need to detect and watermark AI-generated audio, video, and images.
- **What you get**: Cloud, API, and SDK access (REST, Python, Node.js, WebSocket) to Resemble's Chatterbox family of open-source (MIT-licensed) text-to-speech and voice-cloning models, supporting zero-shot voice cloning from as little as 10 seconds of audio, text-based voice design, speech-to-speech voice conversion, audio editing/enhancement, and up to 100 languages on the managed platform. The same account also gives access to Resemble's separate Detect (deepfake detection), Identity (biometric verification), and Watermarker (PerTh audio/video watermarking) products.
- **How it works**: Users record or upload a short voice sample (or generate one from a text description) to create a cloned or designed voice, then call the TTS or speech-to-speech API/SDK to synthesize speech in that voice with adjustable emotion, pronunciation, and language, streamed over WebSocket/HTTP or returned synchronously; models can also be self-hosted via Docker/Kubernetes for on-premise or air-gapped deployment. Billing runs on a Flex pay-as-you-go credit plan (voice cloning: first clone free, then $2 each) or fixed-fee Team/Business/Enterprise subscriptions, and every output can be watermarked with PerTh for provenance tracking.
