Nail IVR pronunciation with SSML.

A phone system reads names, account numbers, and product terms out loud — and plain text-to-speech mangles all three. This playground pairs a plain and an SSML version of four common IVR lines so you can hear the fix. Edit the SSML and re-synthesize. Every call runs through simba-3.2 / geffen_32 server-side; the key never reaches the browser.

SSML supported here: <sub>, <prosody>, and <break>. Wrap everything in <speak>…</speak>.
