KokoClone Adds Voice Cloning to Kokoro TTS

🔑 Enhanced Key Takeaways

• •Kokoro TTS, developed by Hexgrad and founded in 2024 in Singapore, uses an 82 million parameter architecture for efficient deployment on resource-constrained devices like edge hardware[3][6].
• •Prior to KokoClone, Kokoro lacked native zero-shot voice cloning and relied on a curated library of pre-defined voicepacks represented as tensors[3][7].
• •Kokoro processes phoneme sequences generated by espeak-ng to produce 24kHz audio output, enabling compatibility with various applications[6].
• •The model supports deployment on Apple Silicon (M1/M2/M3) via MPS acceleration in addition to NVIDIA GPUs and CPU[4].

🛠️ Technical Deep Dive

• •Base Kokoro-82M model has 82 million parameters, processes phoneme sequences from espeak-ng phonemizer, and generates 24kHz audio[3][6].
• •Designed for lightweight deployment, runs on CPU in real-time via ONNX, with NVIDIA GPU acceleration and Apple Silicon MPS support[4][6].
• •Pre-KokoClone version used fixed set of curated voicepacks as tensor inputs, without native audio-sample-based cloning[3][7].
• •KokoClone extension adds zero-shot cloning capability from short WAV clips while preserving the base model's efficiency[1][3].
