+# Caps Writer
+
+### 简介
+
+一款语音输入工具，后台运行脚本后，按下大写锁定键超过 0.3 秒后，开始语音识别，松开按键之后，自动输入识别结果。
+
+### 描述
+
+本工具（Caps Writer）是一个电脑端的语音输入工具，使用了阿里云的一句话识别 api
+
+（有兴趣的可以改成百度、腾讯、讯飞的 api 试试）。
+
+使用方法很简单：用 python 运行 `run.py` 后，按下 `Caps Lock`（也就是大写锁定键）超过 0.3 秒后，就会开始用阿里云的 api 进行语音识别，松开按键后，会将识别结果自动输入。
+
+对于聊天时候进行快捷输入、写代码时快速加入中文注释非常的方便。
+
+### 视频演示
+
+请到 HacPai 帖子中进行查看：
+
+### 安装使用
+
+本工具是一个python脚本，依赖于以下模块：
+
+- keyboard
+- pyaudio
+- configparser
+- aliyunsdkcore
+- alibabacloud-nls-python-sdk
+
+其中：
+
+- pyaudio 在 windows 上不是太好安装，可以先到 [这个链接](https://www.lfd.uci.edu/~gohlke/pythonlibs) 下载 pyaudio 对应版本的 whl 文件，再用 pip 安装
+- alibabacloud-nls-python-sdk 不是通过 python 安装，而是通过 [阿里云官方文档的方法](https://help.aliyun.com/document_detail/120693.html) 进行安装。
+
+另外，需要在 `run.py` 中填入阿里云拥有 **管理智能语音交互（NLS）** 权限的 **RAM访问控制** 用户的 **accessID**、**accessKey** 和智能语音交互语音识别项目的 **appkey** 。
+
+做完以上步骤后，只要运行 `run.py` 就可以用了！
+
+本文件夹内有一个 `安装指南` 文件夹，在里面可以找到详细的安装指南，还包括了提前下载的 alibabacloud-nls-python-sdk 和 pyaudio 的 whl 文件。
+
+### 后话
+
+因为作者就是本着凑合能用就可以了的心态做这个工具的，所以图形界面什么的也没做，整个工具单纯就一个脚本，功能也就一个，按住大写锁定键开始语音识别，松开后输入结果。目前作者本人已经很满意。
+
+欢迎有想法有能力的人将这个工具加以改进，比如加入讯飞、腾讯、百度的语音识别api，长按0.3秒后开始识别时加一个提示等等等等。

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+
+运行环境
+--------
+
+Python3.4及以上
+
+.. note::
+
+    暂不支持Python2
+
+
+安全方法
+--------

+## 安装依赖
+
+先确保安装了 python
+
+然后打开命令行窗口，切换到本文件夹，用以下命令安装依赖：
+
+```
+pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
+pip install setuptools keyboard aliyunsdkcore configparser
+cd alibabacloud-nls-python-sdk
+python setup.py bdist_egg
+python setup.py install
+```
+
+此外，还有一个依赖 `pyaudio` 不是太好安装，需要先到 [这个链接](https://www.lfd.uci.edu/~gohlke/pythonlibs) 下载 pyaudio 对应版本的 whl 文件。例如，我安装的是 python3.7 64位版本，就下载 `PyAudio‑0.2.11‑cp37‑cp37m‑win_amd64.whl` ，放到本文件夹，用
+
+```
+pip install PyAudio‑0.2.11‑cp37‑cp37m‑win_amd64.whl
+```
+
+安装好 pyaudio。（为了方便，作者已经将 python3.6 到 3.9 的 whl 文件下载到本文件夹，根据版本选择安装即可）
+
+## API 配置
+
+### 开通服务
+
+你需要先到阿云开发者控制台开通 **RAM访问控制** ，进入 **RAM访问控制** 的控制台，新建一个用户，记下它的 **accessID**、**accessKey**，然后再为它添加 **管理智能语音交互（NLS）** 的权限。
+
+接下来开通 **智能语音交互** 服务，新建一个项目：
+
+- 类别：非电话
+- 分类：通用
+- 场景：中文普通话 或 其它语言（想识别哪个语言就用哪个）
+
+发布上线，再记下这个项目的 **appkey**
+
+### 填写 API
+
+用文本编辑器打开项目主目录的 `run.py` 编辑，可以看到：
+
+```python
+""" 在这里填写你的 API 设置 """
+accessID = "xxxxxxxxxxxxxxxxxxxxxxxx"
+accessKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
+appkey = 'xxxxxxxxxxxxxxxx'
+```
+
+将你在阿里云的 **accessID**、**accessKey**、**appkey** 分别填入，保存。
