# Kazakh-VoxCPM-LoRA

## 🇰🇿 Overview

This repository hosts a **LoRA (Low-Rank Adaptation)** model specifically optimized for the **Kazakh language**, built upon the **VoxCPM 1.5** architecture. This research project aims to bridge the gap in high-quality Kazakh speech synthesis, offering a solution that excels in both standard TTS and Zero-shot Voice Cloning while retaining the base model's proficiency in Chinese and English.

## 🚀 Performance Highlights

* **Native Phoneme Mastery**: Precision handling of unique Kazakh phonemes: **ә, ғ, қ, ң, ө, ұ, ү, һ, і**.
* **Superior Prosody**: Achieved a `loss/stop` of **0.003-0.005**, ensuring natural pauses and rhythmic accuracy in long-form text.
* **Advanced Cloning**: Supports high-fidelity voice cloning from as little as 3 seconds of reference audio.
* **Seamless Tri-lingualism**: Integrated support for code-switching across Kazakh, English, and Chinese.

## 📊 Training Specifications

* **Base Model**: [openbmb/VoxCPM1.5]()
* **Dataset**: **66.1 hours** of high-quality Kazakh speech (Source: [issai/KazakhTTS]()).
* **Parameters**: Step: 4160 | Epoch: 1.84 | Rank: 32 | Alpha: 16.
* **Final Metrics**: `loss/diff`: ~0.644 | `loss/stop`: ~0.004.


## 🛠️ Implementation Guide
This model supports dynamic hot-swapping. You can enable Kazakh support by setting `lora_enabled` to `True`. 

For a complete interactive web application and detailed inference scripts, please refer to our GitHub repository:
