+# openai_v2v_python
+
+An extension for integrating OpenAI's Next Generation of **Multimodal** AI into your application, providing configurable AI-driven features such as conversational agents, task automation, and tool integration.
+
+## Features
+
+<!-- main features introduction -->
+
+- OpenAI **Multimodal** Integration: Leverage GPT **Multimodal** models for voice to voice as well as text processing.
+- Configurable: Easily customize API keys, model settings, prompts, temperature, etc.
+- Async Queue Processing: Supports real-time message processing with task cancellation and prioritization.
+<!-- - Tool Support: Integrate external tools like image recognition via OpenAI's API. -->
+
+## API
+
+Refer to `api` definition in [manifest.json] and default values in [property.json](property.json).
+
+<!-- Additional API.md can be referred to if extra introduction needed -->

+| `voice`                     | `string`   | Voice that OpenAI model speeches, such as `alloy`, `echo`, `shimmer`, etc |
+| `server_vad`                | `bool`     | Flag to enable or disable server vad of OpenAI |
+| `language`                  | `string`   | Language that OpenAO model reponds, such as `en-US`, `zh-CN`, etc | 
+| `dump`                      | `bool`     | Flag to enable or disable audio dump for debugging purpose  |
