+## MiniMax TTS（在线、需要API密钥）
+MiniMax提供的在线的TTS服务，`speech-02-turbo`等模型具有强大的TTS性能，并且可以自由定制音色。
+
+### 配置步骤
+1. **获取`group_id`和`api_key`**
+  您可以通过Minimax官网注册来获取`group_id`和`api_key`，[官方教程文档](https://platform.minimaxi.com/document/Fast)
+
+2. **填写`conf.yaml`配置**
+  在配置文件的 `minimax_tts` 段落中，按以下格式填写参数（示例）：
+```yaml
+    minimax_tts:
+      group_id: '' # 你在 Minimax官网获取到 的 group_id
+      api_key: '' # 你在 Minimax官网获取到 的 api_key
+      # 支持的模型: 'speech-02-hd', 'speech-02-turbo'（推荐使用 'speech-02-turbo'）
+      model: 'speech-02-turbo' # minimax 模型名称
+      voice_id: 'female-shaonv' # minimax 语音 id，默认 'female-shaonv'
+      # 自定义发音字典，默认为空。
+      # 示例: '{"tone": ["测试/(ce4)(shi4)", "危险/dangerous"]}'
+      pronunciation_dict: ''
+```
+其中`voice_id`是可以配置的声音音色，具体的支持声音列表可以查看[官方文档中查询可用声音ID的部分](https://platform.minimaxi.com/document/get_voice)。`pronunciation_dict`是可以支持的自定义发声规则，比如您可以把`牛肉`发音为`neuro`，可以用类似示例的方法来定义这个发声规则。

+## MiniMax TTS (Online, API Key Required)
+MiniMax provides an online TTS service where models like `speech-02-turbo` offer powerful TTS capabilities with customizable voice options.
+
+### Configuration Steps
+1. **Obtain `group_id` and `api_key`**
+    You can register on the Minimax official website to get your `group_id` and `api_key`, [Official Documentation](https://platform.minimaxi.com/document/Fast)
+
+2. **Fill in the `conf.yaml` configuration**
+    In the `minimax_tts` section of the configuration file, enter parameters in the following format (example):
+```yaml
+minimax_tts:
+      group_id: '' # Your minimax group_id
+      api_key: '' # Your minimax api_key
+      # Supported models: 'speech-02-hd', 'speech-02-turbo' (recommended: 'speech-02-turbo')
+      model: 'speech-02-turbo' # minimax model name
+      voice_id: 'female-shaonv' # minimax voice id, default is 'female-shaonv'
+      # Custom pronunciation dictionary, default empty.
+      # Example: '{"tone": ["测试/(ce4)(shi4)", "危险/dangerous"]}'
+      pronunciation_dict: ''
+```
+The `voice_id` parameter can be configured to different voice tones. You can check the [voice ID query section in the official documentation](https://platform.minimaxi.com/document/get_voice) for a complete list of supported voices. The `pronunciation_dict` supports custom pronunciation rules - for example, you can define rules to pronounce "牛肉" as "neuro" using the format shown in the example.
