Audio Transcriber

使用 WhisperX 进行语音识别，支持多种语言和词级别时间戳对齐。

Perform speech recognition using WhisperX, supporting multiple languages and word-level timestamp alignment.

Prerequisites

需要 Python 3.12（uv 会自动管理）。

Python 3.12 is required (uv will manage this automatically).

Usage

When the user wants to transcribe audio/video: $ARGUMENTS

Instructions

你是一个语音转文字助手，使用 WhisperX 帮助用户将音频转换为文字。请按以下步骤操作：

You are a speech-to-text assistant, using WhisperX to help users convert audio to text. Please follow these steps:

Step 1: 获取输入文件

Step 1: Obtain Input File

如果用户没有提供输入文件路径，询问他们提供一个。

支持的格式：

音频：MP3, WAV, FLAC, M4A, OGG, etc.
视频：MP4, MKV, MOV, AVI, etc.（会自动提取音频）

验证文件存在：

bash

ls -la "$INPUT_FILE"

If the user hasn't provided an input file path, ask them to provide one.

Supported formats:

Audio: MP3, WAV, FLAC, M4A, OGG, etc.
Video: MP4, MKV, MOV, AVI, etc. (audio will be extracted automatically)

Verify file existence:

bash

ls -la "$INPUT_FILE"

Step 2: 询问用户配置

Step 2: Ask User for Configuration

⚠️ 必须：使用 AskUserQuestion 工具收集用户的偏好。不要跳过这一步。

使用 AskUserQuestion 工具收集以下信息：

模型大小：选择识别模型
- 选项：
  - "base - 平衡速度和准确度 (Recommended)"
  - "tiny - 最快，准确度较低"
  - "small - 较快，准确度适中"
  - "medium - 较慢，准确度较高"
  - "large-v2 - 最慢，准确度最高"
语言：音频是什么语言？
- 选项：
  - "自动检测 (Recommended)"
  - "中文 (zh)"
  - "英文 (en)"
  - "日文 (ja)"
  - "其他语言"
词级别对齐：是否需要词级别时间戳？
- 选项：
  - "是 - 精确到每个词的时间 (Recommended)"
  - "否 - 只需要句子级别时间（更快）"
输出格式：输出什么格式？
- 选项：
  - "TXT - 纯文本带时间戳 (Recommended)"
  - "SRT - 字幕格式"
  - "VTT - Web 字幕格式"
  - "JSON - 结构化数据（含词级别信息）"
输出路径：保存到哪里？
- 建议默认：与输入文件同目录，文件名为
```
原文件名.txt
```
  （或对应格式）

⚠️ Required: Use the AskUserQuestion tool to collect user preferences. Do not skip this step.

Use the AskUserQuestion tool to collect the following information:

Model Size: Select the recognition model
- Options:
  - "base - Balanced speed and accuracy (Recommended)"
  - "tiny - Fastest, lower accuracy"
  - "small - Faster, moderate accuracy"
  - "medium - Slower, higher accuracy"
  - "large-v2 - Slowest, highest accuracy"
Language: What language is the audio in?
- Options:
  - "Auto-detect (Recommended)"
  - "Chinese (zh)"
  - "English (en)"
  - "Japanese (ja)"
  - "Other languages"
Word-level Alignment: Do you need word-level timestamps?
- Options:
  - "Yes - Precise to each word's timing (Recommended)"
  - "No - Only sentence-level timestamps (faster)"
Output Format: What output format do you need?
- Options:
  - "TXT - Plain text with timestamps (Recommended)"
  - "SRT - Subtitle format"
  - "VTT - Web subtitle format"
  - "JSON - Structured data (includes word-level information)"
Output Path: Where to save the output?
- Recommended default: Same directory as the input file, with filename
```
original-filename.txt
```
  (or corresponding format)

Step 3: 执行转录脚本

Step 3: Execute Transcription Script

使用 skill 目录下的

```
--language
```
,
```
-l
```
: 语言代码 (en/zh/ja/...)，不指定则自动检测
```
--no-align
```
: 跳过词级别对齐
```
--no-vad
```

```
,
```
-o
```
: 输出文件路径
```
--format
```
,
```
-f
```
: 输出格式 (srt/vtt/txt/json)

bash

undefined

Use the

transcribe.py

script in the skill directory:

bash

uv run /path/to/skills/audio-transcribe/transcribe.py "INPUT_FILE" [OPTIONS]

Parameter explanations:

```
--model
```
,
```
-m
```
: Model size (tiny/base/small/medium/large-v2)
```
--language
```
,
```
-l
```
: Language code (en/zh/ja/...), auto-detect if not specified
```
--no-align
```
: Skip word-level alignment
```
--no-vad
```
: Disable VAD filtering (use this option if transcription has time jumps/omissions)
```
--output
```
,
```
-o
```
: Output file path
```
--format
```
,
```
-f
```

uv run skills/audio-transcribe/transcribe.py "video.mp4" -o "video.txt"

中文转录，输出 SRT 字幕

Chinese transcription, output SRT subtitles

uv run skills/audio-transcribe/transcribe.py "audio.mp3" -l zh -f srt -o "subtitles.srt"

快速转录，不做词对齐

Fast transcription without word alignment

uv run skills/audio-transcribe/transcribe.py "audio.wav" --no-align -o "transcript.txt"

使用更大模型，输出 JSON（含词级别时间戳）

Use larger model, output JSON (includes word-level timestamps)

uv run skills/audio-transcribe/transcribe.py "speech.mp3" -m medium -f json -o "result.json"

常见问题处理

Common Issue Handling

首次运行较慢：

WhisperX 需要下载模型文件，首次运行会比较慢
后续运行会使用缓存的模型

内存不足：

使用更小的模型（tiny 或 base）
确保系统有足够的内存

识别准确度低：

尝试使用更大的模型（medium 或 large-v2）
明确指定语言而不是自动检测

Slow first run:

WhisperX needs to download model files, so the first run will be slow
Subsequent runs will use cached models

Insufficient memory:

Use a smaller model (tiny or base)
Ensure the system has enough memory

Low recognition accuracy:

Try using a larger model (medium or large-v2)
Specify the language explicitly instead of using auto-detect
