Τι έγινε
Alibaba's Qwen Team released Qwen3.8-LiveTranslate, a real-time interpretation model that listens to live speech and returns translated text and speech while the speaker is still talking. The model features a new Interleave architecture, which improves faithfulness, fluency, and conciseness, reducing average lag from 2.8 seconds to 2.3 seconds. It is available as a hosted API on Alibaba Cloud Model Studio and QwenCloud.
Qwen3.8-LiveTranslate introduces an Interleave architecture that processes live speech (and optional video frames) to produce translated text and audio in real time. It supports 60 languages for text output and 29 languages for both text and audio output, handling speaker diarization, synchronized bilingual display, and long‑context disambiguation.
The model is deployed as a hosted API on Alibaba Cloud Model Studio and QwenCloud under the identifier qwen3.8-livetranslate-flash-realtime, accessible via a WebSocket Realtime API. Default audio settings are 16 kHz PCM input and 24 kHz PCM output, with a default voice named Tina.
Pricing varies by region; Beijing rates are listed in USD (e.g., $5.653, $0.466, $14.133, $22.613). Audio input consumes 7 tokens per second, audio output 12.5 tokens per second, making an hour of bidirectional speech cost roughly $1.54 in Singapore before text and image token charges. The is 53,248 tokens (49,152 input, 4,096 output).

Γιατί έχει σημασία
Qwen3.8-LiveTranslate is significant because it offers real-time simultaneous interpretation across 60 languages, with measurable improvements in latency, faithfulness, fluency, and conciseness. This capability can transform international communications, live events, and global business meetings by delivering near-instant translation, reducing barriers to multilingual interaction and enabling more seamless cross‑language collaboration.
The 18% reduction in average lag (from 2.8 s to 2.3 s) makes the model more suitable for scenarios where immediacy is critical, such as live conferences, diplomatic briefings, and emergency response communications.
Support for a broad set of languages—including major world languages for both text and audio—expands the model's applicability across diverse markets and user groups, potentially lowering the cost and complexity of multilingual services.
Deployment as a hosted API simplifies integration for developers, allowing rapid adoption without the need for on‑premise infrastructure, while transparent token‑based pricing provides clearer cost forecasting for enterprises.
