Native Audio and Dialogue
- →State what H3 generates natively - synchronized stereo audio with on-screen dialogue - and which 11 languages have stable support
- →Write multi-speaker, multilingual dialogue using the documented tags: <d>[LanguageTag]</d>, (S1)/(S1,S2), and the soundscape and music sections
- →Drive a generated voice with reference_audio within its documented rules, and know why the audio track matters downstream
Here is the strange thing about the H3 material circulating online: almost none of it mentions that H3 makes sound. Guides walk through endpoints, pricing, even prompt tips — and describe what is, in their telling, a silent video model.
Under the hood, audio is a first-class citizen of the architecture: the announcement describes a dedicated H3-AudioVAE running at 32 kHz stereo with dual independent channels, sitting alongside the visual pipeline. You do not enable audio, configure audio, or pay separately for audio. Every clip you have generated in this course so far arrived with a soundtrack; this lesson is about directing it instead of receiving it.
