Note from Flexan

I provide GGUFs and quantizations of publicly available models that do not have a GGUF equivalent available yet, usually for models I deem interesting and wish to try out.

If there are some quants missing that you'd like me to add, you may request one in the community tab. If you want to request a public model to be converted, you can also request that in the community tab. If you have questions regarding this model, please refer to the original model repo.

You can find more info about me and what I do here.

Russian Turn Detection Model (Qwen/Qwen3-0.3B Fine-Tuned)

This model is a specialized End-of-Utterance (EOU) / Turn Detection model designed for Russian spoken dialogue systems. It is fine-tuned from Qwen/Qwen/Qwen/Qwen3-0.6B to classify whether a user has finished speaking or is pausing mid-sentence.

It is optimized for real-time voice agents (like those using LiveKit) to minimize interruptions and reduce latency in conversational flows.

🎯 Model Capabilities

Task: Classifies text input as either COMPLETE (user finished) or CONTINUE (user is thinking/pausing).
Language: Russian (primary), handles mixed English/Russian technical terms.
Latency: Extremely fast inference (based on 0.5B parameter model), suitable for edge or cloud deployment.
Nuance: Correctly handles hesitation markers (e.g., "ну...", "эээ...", "как бы") as CONTINUE.

💻 Usage

Inference with Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_name = "RAS1981/qwen3-turn-detector-merged"
device = "cuda" if torch.cuda.is_available() else "cpu"

model = AutoModelForCausalLM.from_pretrained(model_name).to(device)
tokenizer = AutoTokenizer.from_pretrained(model_name)

def predict_turn(text):
    messages = [
        {"role": "system", "content": "Ты голосовой ассистент. Определяй, закончил ли пользователь говорить."},
        {"role": "user", "content": text}
    ]
    
    inputs = tokenizer.apply_chat_template(
        messages,
        tokenize=True,
        add_generation_prompt=True,
        return_tensors="pt"
    ).to(device)

    outputs = model.generate(
        inputs, 
        max_new_tokens=2, 
        use_cache=True, 
        pad_token_id=tokenizer.eos_token_id
    )
    
    decoded = tokenizer.decode(outputs[0][inputs.shape[1]:], skip_special_tokens=True)
    return decoded.strip()

# Test Cases
print(predict_turn("Привет, я хочу заказать пиццу"))  # Output: COMPLETE
print(predict_turn("Ну я думаю что может быть..."))   # Output: CONTINUE

📊 Training Details

Dataset

Source: Custom dataset generated via Gemini 2.5 Flash Lite based on IlyaGusev/ru_turbo_alpaca and ss-corpus-ru.
Preprocessing:
- Converted formal text to spoken Russian (added hesitations, fillers, self-corrections).
- Normalized using NFKC and lowercased specific punctuation.
- Balanced 50/50 split between COMPLETE and CONTINUE labels to prevent bias.
Size: ~400 high-quality curated examples (incremental training).

Hyperparameters

Framework: Unsloth + TRL (SFTTrainer)
Quantization: 4-bit (QLoRA)
Learning Rate: 2e-4
Epochs: 62 (Early stopping based on loss convergence)
Final Loss: ~0.086
Optimizer: AdamW 8-bit

⚠️ Limitations

Context: The model looks at the current utterance context. Extremely long pauses in audio might still need VAD (Voice Activity Detection) support.
Domain: Fine-tuned on general conversation and real-estate inquiries; may need adaptation for highly specific medical or legal jargon.

🛠 Intended Use

LiveKit Agents: Use as a semantic turn detector in the EOU plugin.
Customer Support Bots: Prevent the bot from interrupting users while they think.
Voice Assistants: Improve natural flow in Russian dialogue.
