Resemble AI

Resemble AI is a voice cloning and text-to-speech platform designed for developers and content creators who need custom AI voices. It specializes in high-fidelity voice replication from short recordings and real-time streaming TTS for voice-enabled applications.

Voice cloning: Resemble's core capability is creating a custom AI voice from a recorded sample. Rapid Voice Cloning produces a usable voice from as little as 3 seconds of audio — suitable for quick demos or internal use. Professional Voice Cloning uses longer recordings (10+ minutes) to create a high-fidelity clone suitable for commercial production. The resulting voice can then be used to generate arbitrary text in the original speaker's voice.

Real-time synthesis: The Resemble API supports streaming text-to-speech with low latency — voice output begins generating before the full text input is complete. This makes it suitable for voice agents, real-time IVR systems, and conversational interfaces where response speed is critical.

Emotional and vocal controls: Beyond basic TTS, Resemble supports injecting emotional tone (happy, sad, angry, excited) and speaking style into voice output. Dynamic controls allow manipulating pitch, speaking rate, and energy within a single generation.

Deepfake detection: Resemble includes an AI audio authentication service (PerTh Watermarking) that embeds inaudible watermarks into synthesized audio to identify AI-generated content. This is positioned as a trust and safety feature for organizations deploying voice AI.

Localization: The platform supports 100+ languages for voice generation, and cloned voices can often maintain the speaker's vocal identity while speaking in different languages.

Use cases: Resemble is used for audiobook narration, video game character voices, podcast production, voice assistants, and IVR systems. The developer-focused API and low-latency streaming make it popular in production applications rather than just content creation.

Pricing: Pay-as-you-go starts at $0.006/second of generated audio. Professional clones are $0.006/second with an additional one-time training fee. Custom enterprise plans available for high-volume users.
