Note: We just released a new Beta version of Studio which allows you to adjust the pace, loudness, and pauses. Test out what we're working on.
Our voices avatars are trained from the voices of real people, and they tend to take on the characteristics of those individuals, including pace, pitch, and volume.
We recommend auditioning the voice avatars to determine which voice meets your need for a faster or slower read. You may also adjust the speed via your preferred post-processing tool.
If you need to add pauses to the script, you can try adding punctuation such as commas, periods, hyphens, ellipses, or spaces between lines.
