Polly demo

A short demo on how Amazon Polly can help us


This voice was synthesized with the following markup language:


This is a sample text for the Cardano whiteboard slides.

It's possible to emphasize things like the
<emphasis level="moderate">Ouroboros</emphasis>
protocol or highlight the
<prosody volume="x-loud">treasury</prosody>


And for tricky pronunciations we have phoneme's:
You say, <phoneme alphabet="ipa" ph="pɪˈkɑːn">pecan</phoneme>.
I say, <phoneme alphabet="ipa" ph="ˈpi.kæn">pecan</phoneme>.

After a deep breath
<amazon:breath volume="x-loud" duration="x-long" />
<break time="0.3s"/>
<prosody rate="-10%">
we can say IELE and 1234 or
<say-as interpret-as="spell-out">IELE</say-as>
<say-as interpret-as="digits">1234</say-as>

<amazon:effect name="whispered">
<prosody rate="-10%">
but don't say that too loudly, they will hear us.
