The Qwen3-TTS VoiceDesign model card introduces the direction of designing sounds through natural language. This article refers to the 12Hz, 1.7B VoiceDesign checkpoint and does not replace the functional description of other models in the same series.
Write the sound requirements as audition conditions
When explaining simulated exhibits, you can write at a moderate speed, clear sentence endings, and a stable mood, and prepare a short draft containing numbers, proper names, and pauses. Don’t just write “high-level and infectious”, otherwise different candidate voices will lack a common basis for evaluation.
Compare multiple descriptions using the same manuscript
Only one major requirement was adjusted for each round, recording sound descriptions, model versions and results files. After selecting short sentences, test long paragraphs and consecutive chapters to see if the style drifts. The generated results still require manual audition, and "support control" cannot be interpreted as accurately meeting the requirements every time.
Sound usage needs to be confirmed separately
When it comes to identifying real people, brand identities or public communication, authorization and corresponding identification requirements should be confirmed. Sound design and sound cloning are not the same service, and the delivery description should clearly state the specific method used. ChinaOPC has not conducted sound quality evaluation, and customers should submit complete samples and actual playback equipment for acceptance.
