Llm Guided Speech Enhancement

The `dpo-adapter/` checkpoint is based on `Qwen/Qwen2.5-7B-Instruct`. ## Intended use Given structured acoustic evidence, the adapter produces an interpretable response comprising a degradation diagnosis, a DSP-oriented enhancement strategy, and a rationale. It is intended as a research and prototyping control layer, not as a standalone waveform denoiser. ## Training Training examples were generated from AISHELL-1 clean-speech metadata and programmatically sampled degradations. Supervised fine-tuning was followed by Direct Preference Optimization. The synthetic construction makes the response format highly regular. ## Limitations Reported held-out format and diagnosis metrics are in-distribution metrics against programmatically constructed targets. They do not demonstrate generalization to arbitrary recordings or superiority on perceptual speech-enhancement benchmarks. Use the adapters with the Qwen and AISHELL-1 licenses/terms in mind. ## Usage ```python from transformers import AutoModelForCausalLM, AutoTokenizer from peft import PeftModel base_id = "Qwen/Qwen2.5-7B-Instruct" tokenizer = AutoTokenizer.from_pretrained(base_id, trust_remote_code=True) base = AutoModelForCausalLM.from_pretrained(base_id, device_map="auto", trust_remote_code=True) model = PeftModel.from_pretrained(base, "jatshi/llm-guided-speech-enhancement", subfolder="dpo-adapter") ``` Source code: https://github.com/Jatshi/llm-guided-speech-enhancement
