Quick reference

Pause

<break time="600ms"/> or <break strength="strong"/> inserts real silence.

Prosody (rate / pitch / volume)

<prosody rate="slow" pitch="+2st" volume="loud">text</prosody>. Accepts keywords (slow, fast, high, low, soft, loud), percentages (90%, +20%), semitones (+2st), and Hz (+10Hz).

Emphasis

<emphasis level="strong">word</emphasis> makes a word stand out.

Pronunciation

<sub alias="eye-doss speech">eidosSpeech</sub> speaks the alias instead of the written text — perfect for names, brands, and numbers.

Note: this playground runs on free neural voices, which support pauses, prosody, emphasis, and substitution. Azure-style emotion tags (mstts:express-as) are not supported and are ignored.
