Speaking softly

<amazon:effect phonation="soft">

This tag is currently supported only by the standard TTS format.

To specify that input text should be spoken in a softer-than-normal voice, use the <amazon:effect phonation="soft"> tag.

This uses the syntax:

<amazon:effect phonation="soft">text</amazon:effect>

For example, you might use this tag with the Matthew voice as follows:

<speak>
     This is Matthew speaking in my normal voice. <amazon:effect phonation="soft">This 
     is Matthew speaking in my softer voice.</amazon:effect>
</speak>
