Hi Jason,

Glad to hear you're enjoying Voki! You can change the speed of the voice by using SSML tags! Decrease the rate by pasting this code into the TTS box:
<prosody rate="slow"> YOUR TEXT </prosody>

Voki Classroom and Voki Presenter allows users to have increased audio length. Our free Voki product supports up to 60 seconds of recorded audio, which is around 600 characters for TTS. Voki Classroom and Voki Presenter can support up to 90 seconds, which is around 900 characters.
