## Overview

Qwen-Audio-3.1-Realtime is the live voice-conversation model in Qwen-Audio-3.1, Alibaba's speech release announced by the Qwen team on 23 September 2026. The QwenCloud model changelog lists it on 20 September 2026 under the model id `qwen-audio-3.1-realtime-plus`, describing real-time duplex speech conversations that use the same integration protocol as the 3.0 Plus model, so existing integrations carry over.

It is an end-to-end speech-to-speech model: one connection takes the user's audio and returns spoken and text replies, without separate recognition and synthesis calls. Alibaba Cloud Model Studio describes it as a real-time duplex speech model with text and audio input and output, function calling, web search and voice cloning; web search and function calling cannot be enabled at the same time. It is served over WebSocket, AOQ and WebRTC, with server VAD, smart turn detection or client-controlled turns.

The model has a 262,144-token context window, with up to 245,760 input and 16,384 output tokens, and keeps up to 50 audio turns or 300 seconds of audio as conversation history. It supports German, English, Spanish, French, Indonesian, Italian, Japanese, Korean, Portuguese, Russian and Chinese, plus 20 Chinese regional varieties. The release keeps the earlier voices and adds eight system voices, for 13 in total, alongside cloned voices.

In Singapore the model page lists $0.8 per 1M text input tokens, $6.4 per 1M audio input tokens, $6.4 per 1M text output tokens and $24 per 1M audio output tokens; China (Beijing) lists $0.688, $5.501, $5.501 and $20.628. Both regions allow 60 requests and 100,000 tokens per minute.
