The model supports 70+ languages, 30 prebuilt voices, and over 200 audio tags that can be embedded directly into text prompts to control pacing, expression, and vocal style. Tags like [whispers], [panic], [slow], and [long pause] are inserted inline to steer delivery with granular precision. The post covers the core prompting framework, common tags, and practical use cases including audiobooks, gaming accessibility descriptions, banking fraud alerts, and automated flight notifications. Audio output is watermarked with SynthID for AI content identification. ## Full article daily.dev links to this article rather than hosting it.
