Qwen-Audio-3.0-TTS-Plus Illustrated Guide Narration

Use the Plus audio-quality mode of Qwen-Audio-3.0-TTS-Plus to synthesize Chinese narration for a "Prompt Engineering Visualization: Descriptive Structure Illustrated Guide." The text is deliberately written as a structured guide voiceover script: first present the layered framework of a prompt (goal, constraints, context, output format), then explain the role and common mistakes of each layer one by one, making it easy to play in sequence alongside image cards or a long infographic. In base, fix voice=longanlingxin built-in female voice, wav output, and 24kHz sample rate, and use instruction to specify "steady, teaching-oriented pacing and emphasis," demonstrating the model's ability to adjust synthesis effects via instructions. Suitable for scenarios such as course dubbing, reading product documentation aloud, and audio versions of long illustrated posts—situations sensitive to naturalness but with low throughput-speed requirements. Note that the model generates at roughly 16 characters per second and bills by character, so long texts should be synthesized in segments.
