DashScope Realtime ASR & TTS SDK
Project description
DashScope Realtime
🚀 Async Python SDK for DashScope Realtime ASR (Speech Recognition) & TTS (Speech Synthesis)
简介
DashScope Realtime 是一个支持异步 WebSocket 的 Python SDK,适配阿里 DashScope 的实时流式语音识别(ASR)和流式语音合成(TTS)能力。
为什么开发这个项目?
阿里云官方提供的DashScope Python SDK 是同步 WebSocket 实现,存在以下问题:
-
不支持 async / await
-
回调不在同一事件循环,无法直接使用 async 上下文
-
与 OpenAI API 生态的开源项目(如 FastAPI、Chainlit)不兼容
为了解决这些问题,本项目基于 DashScope WebSocket API,重新实现了异步版本的 ASR(语音识别)与 TTS(语音合成)SDK,具备:
-
纯异步 API 设计
-
支持流式音频输入输出
-
支持上下文无感知切换
-
更易接入 OpenAI API 风格的开源项目
安装
pip install dashscope-realtime
快速上手
实时语音识别(ASR)
from dashscope_realtime import DashScopeRealtimeASR
async with DashScopeRealtimeASR(api_key="your-api-key") as asr:
await asr.send_audio(b"...") # 发送音频片段
实时语音合成(TTS)
from dashscope_realtime import DashScopeRealtimeTTS
async with DashScopeRealtimeTTS(api_key="your-api-key") as tts:
await tts.say("Hello, DashScope!") # 发送文本
await tts.finish() # 完成任务
特性
- ✅ 全异步设计(async / await)
- ✅ ASR 支持流式音频输入
- ✅ TTS 支持流式音频输出
- ✅ 自动重连 & 错误处理
- ✅ 接口风格对齐 OpenAI Realtime
- ✅ 方便集成任意异步 Python 项目
