I would like to reduce the speaking speed. How can I do it?

Hi - you can use SSML prosody tags in the text to control the speed.

This will not work with all voices though - so you may need to experiment. Here's an example -

You surround your text with the brackets as you see below - and it will speak slower.

<prosody rate="slow"> hello there 1 2 3 4 5 6 7 8 9 </prosody>

For more fine tuned control, use the following syntax (supported by a further subset of voices)

<prosody rate="-10%"> hello there 1 2 3 4 5 6 7 8 9</prosody>

As noted - only a subset of the voices will respond. Supported voices include -

Kate

Paul

Julie

Bridget

Hugh

Ashley

James

Let me know how goes.
