# ASR Personal Hotword Miner — OpenClaw Skill ## 功能 从 OpenClaw 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 session 对话 → 调用远端 asr-corrector 服务 → 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 安装到当前 agent 的工作空间 skills 目录下。 **安装位置解析步骤：** 1. 获取当前 session 的 agent 名称（如 `main`、`doctor`） 2. 读取 `~/.openclaw/openclaw.json`，在 `agents.list` 中找到该 agent 的 `workspace` 配置；如果 agent 没有独立 `workspace`，则使用 `agents.defaults.workspace` 3. 将 skill 安装到 `{workspace}/skills/asr-personal-hotwords/` **示例：** - main agent（workspace: `~/.openclaw/workspace`）→ `~/.openclaw/workspace/skills/asr-personal-hotwords/` - doctor agent（workspace: `~/.openclaw/workspace-doctor`）→ `~/.openclaw/workspace-doctor/skills/asr-personal-hotwords/` ### Step 2: 检查依赖 ```bash pip3 install requests pyyaml --quiet ``` ### Step 3: 验证远端服务 ```bash curl -s http://124.174.11.138:65000/health ``` 如果服务不可用，通知用户并中止安装。 ### 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 && bash run.sh ``` 运行完成后会自动导出 hotwords.md。 ### Step 6: 记录热词表路径 在当前 agent 工作空间的 `TOOLS.md` 中追加热词表配置（路径根据实际 workspace 动态生成）： ```markdown ## ASR 热词（歧义词）表 - **路径**: {workspace}/skills/asr-personal-hotwords/hotwords.md - **用途**: 使用 ASR 模型转录语音时，自动读取此文件注入 prompt - **更新**: 手动执行或定时自动更新 ``` 其中 `{workspace}` 替换为 Step 1 中解析到的实际路径。 ### Step 7: 询问执行方式 向用户提问： > "热词挖掘 skill 安装成功！默认为手动执行模式。 > 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）" **如果用户同意定时执行：** 1. 询问用户期望的执行时间（默认建议：每天 02:00） 2. 使用 OpenClaw cron 创建定时任务，任务内容： - 以 sub-agent 方式执行（`sessions_spawn`, `runtime: "subagent"`, `mode: "run"`） - 任务步骤： 1. `cd SKILL_DIR && bash run.sh` 2. 将结果摘要推送到 Telegram + 飞书 - 执行完 sub-agent 自动销毁 **如果用户拒绝：** 仅确认安装完成，后续用户手动触发即可。 ## 手动执行 当用户触发此 skill 时： ### 默认：挖掘前一天 ```bash cd SKILL_DIR && bash run.sh ``` ### 指定日期 ```bash cd SKILL_DIR && bash run.sh --date 2026-04-26 ``` ### 指定日期范围 ```bash cd SKILL_DIR && bash run.sh --start 2026-04-20 --end 2026-04-26 ``` ### 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） | ## 配置 编辑 `config.yaml`： - `server_url`：asr-corrector 远端服务地址 - `extract.agents`：要提取的 agent 列表（`["self"]` 为当前 agent，`["*"]` 为全部） - `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 Personal Hotwords

An OpenClaw skill that automatically mines personalized hotwords and ambiguous terms from OpenClaw conversation histories, powered by the [asr-corrector](https://github.com/asr-corrector) service.

## Overview

ASR (Automatic Speech Recognition) systems often misrecognize domain-specific terms, proper nouns, and niche vocabulary. This tool extracts conversation data from OpenClaw agent sessions and feeds it into a hotword mining pipeline to build a **per-agent personalized** 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:**

```
OpenClaw Sessions (.jsonl) → Extract & Filter → asr-corrector API → Vocabulary Table → hotwords.md
```

## Features

- **Per-agent isolation** — Each agent maintains its own hotword table; `["self"]` mode auto-detects the current agent from skill path + `openclaw.json`
- **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 (not just the latest), vocabulary only grows
- **Auto-chunking** — Splits large data into API-compliant chunks (≤400 lines / ≤10,000 chars) and merges results with deduplication
- **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
- **HTTP retry** — 3 retries with exponential backoff for 502/503/504 errors
- **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+
- A running [asr-corrector](https://github.com/asr-corrector) service
- OpenClaw installed with session history in `~/.openclaw/agents/`

**Python dependencies:**

```bash
pip install requests pyyaml
```

## Installation

This skill is designed to be installed **per-agent** in the agent's workspace:

1. Determine the agent's workspace from `~/.openclaw/openclaw.json` (`agents.list[].workspace` or `agents.defaults.workspace`)
2. Install to `{workspace}/skills/asr-personal-hotwords/`

```bash
# Install to agent workspace
clawhub install asr-personal-hotwords
```

See `SKILL.md` for the full 7-step installation wizard.

## Quick Start

```bash
# Mine yesterday's conversations (default)
bash run.sh

# Mine a specific date
bash run.sh --date 2026-04-26

# Mine a date range
bash run.sh --start 2026-04-20 --end 2026-04-26

# Export hotword table only (no mining)
bash run.sh --export-only -f prompt -o hotwords.md
```

## Configuration

Edit `config.yaml`:

```yaml
# Remote asr-corrector service
server_url: "http://124.174.11.138:65000"

# Extraction settings
extract:
  agents: ["self"]            # ["self"] = auto-detect, ["*"] = all, or ["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/{agent}/sessions/*.jsonl` files and extracts `user`/`assistant` message pairs for the target date(s).

**Agent resolution (`["self"]` mode):**
1. Infers workspace path from the skill's file location
2. Looks up `~/.openclaw/openclaw.json` to find the matching agent by workspace path
3. Falls back to `OPENCLAW_AGENT_NAME` env var, then `"main"`

**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. This ensures the vocabulary only grows over time — terms discovered in earlier runs are never lost.

### 3. API Submission (`run.py`)

Chat data is submitted to the asr-corrector service's `/api/build-vocab` endpoint. If data exceeds API limits, it is automatically split into chunks. Each chunk is submitted as a separate task, polled for completion, and results are merged with deduplication and frequency aggregation.

**Reliability:**
- HTTP requests use a retry-enabled session (3 retries, exponential backoff, 502/503/504)
- Task polling with configurable timeout (default 600s)
- Same-date re-runs automatically back up previous results

### 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
```

Merges all historical vocab files and exports a clean hotword table.

**Supported formats:**

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

Entries with both empty `desc` and empty `possible_asr_errors` are automatically filtered out.

### 5. ASR Integration

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