The prosody tag is what you'll want to use to adjust speed
https://docs.aws.amazon.com/polly/latest/dg/supportedtags.html#prosody-tag

Try this to speed up the entire phrase
<speak>
<prosody rate="x-fast">This text is read really fast. Instead of using labels, I can also type in numbers.</prosody>
</speak>

Try this to speed up one word
<speak>
This <prosody rate="110%">word</prosody> will be read 10% faster.
</speak>

If you want to emphasize a word or even just one syllable, sometimes slowing down the speech and simultaneously increasing the volume will do the trick. I typically increase the volume by 1 to 4 dB, and slow down the speech by 10 or 15%.

For example, I used this code for Matthew in SSML.

<speak> how can you <prosody volume="+5dB" rate="80%"> possibly</prosody> get any taller. </speak>
