How we work: https://postcutoff.com/about/ Canonical page: https://postcutoff.com/e/2026-09-23-qwen-audio-3-1/ # Alibaba launches Qwen-Audio-3.1 five-model voice stack and cuts audio API prices up to 95% Around its 2026 Apsara Conference Alibaba's Qwen team released Qwen-Audio-3.1: upgraded ASR, TTS and full-duplex Realtime models plus two new ones (ASR-Next for audio understanding, TTS-Next for one-pass speech+SFX+ambience generation), with price cuts of ~70% (TTS), ~85% (Realtime) and up to 95% (ASR). Qwen3.8-LiveTranslate (60 input languages, 29 with voice output) debuted alongside. ## Key facts - Five models: Qwen-Audio-3.1-ASR, -ASR-Next, -TTS, -TTS-Next, -Realtime - qwen-audio-3.1-realtime-plus: 262K context; $6.40 audio in / $24 audio out per 1M tokens on QwenCloud - Realtime task success 82.0% (from 78.4%); response rate to background speech cut from 73.0% to 13.0% (arXiv 2609.25176) - qwen-audio-3.1-tts-next (model docs dated 2026-09-22): zh/en, up to 3,000 chars, up to 240 s podcast output - Qwen3.8-LiveTranslate (announced 2026-09-19, id qwen3.8-livetranslate-flash-realtime): LAAL latency cut from 2.8 s to 2.3 s; 60 input / 29 voice-output languages; $7.50 audio in / $30 audio out per 1M tokens; API-only ## What happened Alibaba's Qwen team shipped a complete hosted audio stack in one release: recognition (ASR, ASR-Next with diarization, emotion and sound-event detection), synthesis (TTS with cross-language voice transfer, TTS-Next that mixes speech, sound effects and ambience in one pass) and a full-duplex Realtime model with tool use and web search. It came two months after Qwen-Audio-3.0 (July 2026, see [2026-07-20-qwen-audio-3-0-tts](https://postcutoff.com/e/2026-07-20-qwen-audio-3-0-tts/index.md)) and alongside Qwen3.8-LiveTranslate at Apsara 2026. ## Why it matters Chinese labs (Alibaba, StepFun, ByteDance) now field voice-agent models that top or approach GPT-Live / Gemini Live on public leaderboards at a fraction of the price, turning real-time voice into a price war. The exact API ids of the 3.1 TTS and ASR-Next models (not in the international Model Studio docs as of 2026-09-29; only qwen-audio-3.0-tts-flash/-plus and qwen-audio-3.1-asr-flash-streaming/-filetrans are listed), and Model Studio international prices were not verified. ## Your AI and this story - GPT-6 Astra (training cutoff April 2026): 146 days after its cutoff - Claude Opus 5.5 (training cutoff June 2026): 85 days after its cutoff - Gemini 4 Hydrogen (training cutoff March 2026): 176 days after its cutoff - Grok 4.7 (training cutoff May 2026): 115 days after its cutoff ## Sources 1.
