Skill: lovejing0306/asr-hotwords (version 2.0.0)

# ASR Hotwords — OpenClaw Skill ## 功能 从 OpenClaw 所有 agent 的对话记录中自动挖掘热词/歧义词表，供 ASR 模型提升语音转录准确性。 **Pipeline**: 提取所有 session 对话 → 本地热词挖掘（jieba 分词 + LLM 精炼） → 输出歧义词表 → 自动导出 hotwords.md ## 触发条件 用户说以下类似的话时触发此 skill： - "挖掘对话中的热词" - "提取对话歧义词" - "跑一下热词挖掘" - "更新热词表" ## 安装流程 当用户要求安装/启用此 skill 时，按以下步骤执行： **注意：以下所有路径中的 `SKILL_DIR` 指此 SKILL.md 所在目录（即 skill 的根目录）。执行时用 `read` 工具获取本文件路径，取其父目录即可。** ### Step 1: 安装 Skill 将 skill 安装到 `~/.openclaw/skills/asr-hotwords/`。 ```bash # 如果是从其他位置安装 cp -r <source> ~/.openclaw/skills/asr-hotwords/ ``` ### Step 2: 旧版迁移（自动） 运行迁移脚本，自动检测旧版 per-agent 安装并合并数据： ```bash cd SKILL_DIR && python3 migrate.py ``` 迁移脚本会： - 扫描所有 agent workspace 下的旧版 `asr-hotwords` 或 `asr-personal-hotwords` 目录 - 合并 `output/vocab_*.json` 历史挖掘结果到新位置（不覆盖） - 迁移 `.installed` / `.cron_configured` 标记文件 - 迁移 `hotwords.md` - 在旧目录写入 `MIGRATED.md` 标记 如果没有旧版安装，脚本会提示"无需迁移"并跳过。 ### Step 3: 安装依赖 ```bash pip3 install -r SKILL_DIR/requirements.txt --quiet ``` ### Step 4: 验证 OpenClaw LLM 配置 检查 `~/.openclaw/openclaw.json` 中是否存在有效的 provider 配置（apiKey + baseUrl）。 ### Step 5: 测试运行 用前一天的数据跑一次完整 pipeline，确认端到端流程正常： ```bash cd SKILL_DIR && nohup bash run.sh > run.log 2>&1 & ``` 运行完成后会自动导出 hotwords.md。可通过 `tail -f SKILL_DIR/run.log` 查看进度。 ### Step 6: 设置安装标记 ```bash touch SKILL_DIR/.installed ``` 安装完成，通知用户 skill 已就绪。 ## 首次使用引导 当用户首次触发此 skill 时（通过触发条件中的关键词），检查 SKILL_DIR 下是否存在 `.cron_configured` 文件： **如果 `.cron_configured` 不存在（首次使用）：** 在执行挖掘之前，先向用户提问： > "这是首次使用热词挖掘 skill。是否需要设置**每日定时执行**？（推荐：每天凌晨自动挖掘前一天的对话热词并更新 hotwords.md）" - **用户同意**：询问执行时间（默认 02:00），创建 OpenClaw cron 定时任务（sub-agent 方式），然后创建 `.cron_configured` 文件 - **用户拒绝**：直接创建 `.cron_configured` 文件（标记为已询问，不再重复提问） ```bash touch SKILL_DIR/.cron_configured ``` **如果 `.cron_configured` 已存在：** 跳过引导，直接执行。 ## 手动执行 ### 默认：挖掘前一天 ```bash cd SKILL_DIR && nohup bash run.sh > run.log 2>&1 & ``` ### 指定日期 ```bash cd SKILL_DIR && nohup bash run.sh --date 2026-04-26 > run.log 2>&1 & ``` ### 指定日期范围 ```bash cd SKILL_DIR && nohup bash run.sh --start 2026-04-20 --end 2026-04-26 > run.log 2>&1 & ``` ### 仅导出热词表（不重新挖掘） ```bash cd SKILL_DIR && bash run.sh --export-only cd SKILL_DIR && bash run.sh --export-only -f json -o hotwords.json cd SKILL_DIR && bash run.sh --export-only -f csv -o hotwords.csv cd SKILL_DIR && bash run.sh --export-only -f txt ``` 执行完成后，向用户汇报： - 提取了多少条消息 - 挖掘出多少条热词 - 展示 top 10 热词 ## 输出文件 | 文件 | 说明 | |------|------| | `output/vocab_{date}.json` | 原始挖掘结果（按日期存档） | | `hotwords.md` | 热词表（每次运行自动导出，prompt 格式，供 ASR 模型直接使用） | ## DMWork 语音纠错上下文注入 挖掘完成后，run.py 会自动通过 `openclaw gateway call agent` 发送结构化消息给 agent。 agent 收到消息后必须执行： 1. 读取 SKILL_DIR/hotwords.md 2. 调用 `dmwork_management(action="voice-context-update", content=文件内容)` 3. 调用 `dmwork_management(action="voice-context-read")` 验证注入成功 如果是手动执行挖掘，agent 在汇报结果后也应主动执行上述注入步骤。 ## 配置 编辑 `config.yaml`： - `extract.agents`：要提取的 agent 列表（`["*"]` 为全部，或指定如 `["main", "claude"]`） - `extract.max_content_len`：单条消息最大字符数 - `extract.min_freq`：最低词频阈值 LLM API key 和模型信息自动从 `~/.openclaw/openclaw.json` 读取，无需手动配置。 ## 锚点词表机制 - **首次运行**：anchors 为空 - **后续运行**：自动加载 `output/` 目录下所有历史 vocab 结果作为 anchors（合并去重） - 词表只增不减，持续积累

content: # ASR Hotwords

An OpenClaw skill that automatically mines hotwords and ambiguous terms from all OpenClaw agent conversation histories using a local NLP pipeline (jieba + fuzzy pinyin + LLM refinement).

## Overview

ASR (Automatic Speech Recognition) systems often misrecognize domain-specific terms, proper nouns, and niche vocabulary. This tool extracts conversation data from **all** OpenClaw agent sessions and runs a local hotword mining pipeline to build a unified disambiguation vocabulary table.

The generated hotword table (`hotwords.md`) can be directly injected into ASR model prompts (e.g., Qwen2.5-Omni) to improve transcription accuracy.

**Pipeline:**

```
All OpenClaw Sessions (.jsonl) → Extract & Filter → Local Mining (jieba + LLM) → Vocabulary Table → hotwords.md
```

## Features

- **Fully local processing** — All mining runs locally; API key is only used to call your configured LLM directly, never sent to third-party servers
- **Global hotword table** — Scans all agents' sessions, builds a unified vocabulary
- **Smart filtering** — Skips system noise (cron tasks, heartbeats, sub-agent metadata, NO_REPLY, pure English, URLs, code blocks)
- **Incremental anchors** — Loads all historical vocab results as anchors, vocabulary only grows
- **Zero-config credentials** — Reads LLM API key, base URL, and model from `~/.openclaw/openclaw.json` automatically
- **UTC→CST date handling** — Correctly filters messages by CST date, not UTC
- **Safe re-runs** — Automatically backs up previous results when re-running the same date
- **Multiple export formats** — txt, json, csv, prompt (for ASR injection)

```

## Prerequisites

- Python 3.9+
- OpenClaw installed with session history in `~/.openclaw/agents/`

**Python dependencies:**

```bash
pip install -r requirements.txt
```

Dependencies: `pyyaml`, `jieba`, `pypinyin`, `openai`, `anthropic`

## Installation

Install to `~/.openclaw/skills/asr-hotwords/`:

```bash
# Install via ClawHub
clawhub install asr-hotwords
```

See `SKILL.md` for the full installation wizard.

## Quick Start

```bash
# Mine yesterday's conversations (default, background)
nohup bash run.sh > run.log 2>&1 &

# Mine a specific date
nohup bash run.sh --date 2026-04-26 > run.log 2>&1 &

# Mine a date range
nohup bash run.sh --start 2026-04-20 --end 2026-04-26 > run.log 2>&1 &

# Export only (no mining, runs instantly)
bash run.sh --export-only -f prompt -o hotwords.md
```

## Configuration

Edit `config.yaml`:

```yaml
extract:
  agents: ["*"]               # ["*"] = all agents, or specify ["main", "claude"]
  max_content_len: 300        # Max chars per message (truncates beyond)
  min_freq: 3                 # Minimum word frequency threshold
```

### Credential Resolution

LLM API key, base URL, and model are **automatically** resolved from `~/.openclaw/openclaw.json`:

```
agents.defaults.model.primary → "provider/model_id"
    ↓
models.providers.{provider} → apiKey, baseUrl, api format
```

No manual API key or model configuration is needed.

## How It Works

### 1. Session Extraction (`extract_sessions.py`)

Scans `~/.openclaw/agents/*/sessions/*.jsonl` files and extracts `user`/`assistant` message pairs for the target date(s) from all agents.

**Filtering rules:**
- Only `type: "message"` with `role: "user"` or `role: "assistant"`
- UTC timestamps converted to CST before date comparison
- Skips: NO_REPLY, HEARTBEAT_OK, cron contexts, sub-agent metadata, system internals, pure JSON, code blocks, pure English (no Chinese characters), URLs
- Files with mtime before target date are skipped entirely (fast path)
- Messages truncated to `max_content_len` characters
- Output format: `发送者：内容` (one message per line)

### 2. Anchor Loading

Loads all `output/vocab_*.json` files (excluding `.bak` backups), merges by term with deduplication. Vocabulary only grows over time — terms discovered in earlier runs are never lost.

### 3. Local Mining (`build_words.py`)

Runs a 5-stage pipeline locally:

1. **Data Preparation** — Parse chat + load anchors + build fuzzy pinyin index
2. **Data Cleaning** — Rule-based pre-analysis + LLM correction
3. **Statistical Filter** — Word frequency + fuzzy pinyin collision detection
4. **LLM Refinement** — Review + supplement + mixed Chinese/English + scene description
5. **Validation** (optional) — Reverse injection testing

All LLM calls go directly to your configured provider.

### 4. Export (integrated in `run.py`)

`run.py` automatically exports `hotwords.md` after mining. For standalone export:

```bash
bash run.sh --export-only -f prompt -o hotwords.md
```

**Supported formats:**

| Format | Command | Use Case |
|--------|---------|----------|
| `prompt` | `-f prompt -o hotwords.md` | Direct ASR prompt injection |
| `json` | `-f json -o hotwords.json` | Programmatic access |
| `csv` | `-f csv -o hotwords.csv` | Human review / spreadsheet |
| `txt` | `-f txt` | Simple word list |

### 5. ASR Integration

The generated `hotwords.md` is in prompt format, ready to be injected into ASR model system prompts:

```
产品术语：飞书、OpenClaw、ClawHub
技术术语：VLA、持久化、多模态
人名：小苝
易混淆词：飞书/飞鼠、VLA/微辣
```

对每个英文词列出 2-3 个可能的中文误识别结果。
