Resemble Now Available on fal

Today, we’re excited to announce our partnership with Resemble AI, bringing their powerful suite of real-time, high-fidelity text-to-speech and voice cloning models to the fal platform.

Introducing Resemble AI on fal

Resemble AI sets a new benchmark in TTS by combining zero-shot voice cloning, expressive speech synthesis, and real-time inference. This new integration unlocks advanced voice capabilities for creators, developers, and product teams—all accessible through fal’s simple, developer-friendly APIs.

Key features include:

  • Zero-Shot Voice Cloning: Instantly clone any voice with just a few seconds of reference audio—no additional training required.
  • Emotion Exaggeration Control: Adjust the emotional intensity of the synthesized voice from monotone to highly expressive using a single parameter.
  • Alignment-Informed Generation: Ensures ultra-stable and coherent speech output.
  • Real-Time Inference: Achieve faster-than-real-time voice synthesis, ideal for interactive applications.
  • Easy Voice Conversion: Supports voice conversion out of the box.

Try out the models

Chatterbox (OSS) - Text to Speech: Generate expressive, natural speech with Resemble AI's Chatterbox. Features unique emotion control, instant voice cloning from short audio, and built-in watermarking.

Chatterbox (OSS) - Speech to Speech: Convert audio to new voices or your own samples, with expressive results and built-in perceptual watermarking.

Chatterbox HD - Text to Speech: Generate expressive, natural speech with Resemble AI's Chatterbox. Higher-sampling-rate version than available OSS (OSS is 24kHz; HD supports up to 48kHz) with newer weights for improved zero-shot accent capture and pre-built voices

Chatterbox Pro: Coming Soon!

Hear It in Action

Example #1:

Text Input: "My name is Maximus Decimus Meridius, commander of the Armies of the North, General of the Felix Legions and loyal servant to the true emperor, Marcus Aurelius. Father to a murdered son, husband to a murdered wife. And I will have my vengeance, in this life or the next.”

Getting Started with High-Quality Results

Creating High-Quality Voice Clones

The model will mimic the audio fidelity and voice characteristics of the input. To achieve the best results, ensure you use clean audio featuring a single speaker - ideally recorded with a professional microphone. Fast tips;

  • Use at least 10 seconds of clean speech from a single speaker.
  • Record at 24kHz or higher, ideally with a professional microphone and no background noise.
  • Match the speaking style of your reference audio to your intended output (e.g., use audiobook-style speech for audiobook generation).

Generating Conversational Speech

For natural, conversational voices—ideal for voice agents—adjust the model settings:

  • Default values (exaggeration = 0.5, cfg = 0.5) perform well in most cases.
  • If your reference speaker talks quickly, reduce cfg to ~0.3 to improve pacing.

Generating Expressive or Dramatic Speech

For dramatic or emotional speech—great for film, games, or ads:

  • Lower cfg to ~0.3 and increase exaggeration to 0.7 or higher.
  • Higher exaggeration speeds up delivery; reducing cfg helps balance the pacing.

What to Know About Model Constraints

  • Accent Preservation
    Zero-shot cloning may favor American or British English accents and may weaken regional accents in the output.
  • Language Support
    Currently, the model supports English text only.
