SSML Markup Builder
Build and validate speech markup locally in your browser
About
Edit speech segments and inspect live SSML XML. Validation checks balanced tags, allowed attributes, say-as types, and break time formats entirely in your browser.
About this tool
Create deterministic SSML with prosody, breaks, emphasis, say-as, and substitutions, then validate it locally. SSML Markup Builder runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- SSML Markup Builder is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
