- alibaba/qwen-audio-3.0-tts-flash: [Core Function] Qwen-Audio 3.0 TTS Flash is Alibaba’s low-latency Qwen-Audio text-to-speech model on the same SpeechSynthesizer endpoint family as CosyVoice. [Strengths] Fast synthesis with voice, format, sample-rate, prosody, SSML, instruction, language_hint, and AIGC watermark controls; system voices include longanhuan_v3.6, longjielidou_v3.6, loongeva_v3.6, and loongjohn (see the Qwen-Audio-TTS voice list). [Best For] Voice assistants, interactive prompts, short announcements, multilingual product flows, and latency-sensitive batch TTS using Qwen-Audio voices. [Limitations] Do NOT mix Plus-only voices (e.g. longanlingxin) with Flash. Use Plus when maximum narration quality matters more than turnaround time. [Routing] Choose Flash when speed matters most. Choose qwen-audio-3.0-tts-plus for premium narration quality.
