Choose an audio player that's capable of playing mp3s from an http server. Put the iSpeech API text-to-speech request URL in the audio file field.
For example,
Code:
<audio preload="auto" autoplay="autoplay"><source src="https://api.ispeech.org/api/rest?voice=usenglishfemale&action=convert&text=a&apikey=developerdemokeydeveloperdemokey&speed=0"></source></audio>
Another example,
Code:
<iframe src="https://api.ispeech.org/api/rest?voice=usenglishfemale&action=convert&text=a&apikey=developerdemokeydeveloperdemokey&speed=0"></iframe>

Code:
<object type="application/x-shockwave-flash" data="/dewplayer.swf" width="1" height="1" id="dewplayer" name="dewplayer"> <param name="wmode" value="transparent" /><param name="movie" value="dewplayer.swf" /> <param name="flashvars" value="mp3='+encodeURIComponent('https://api.ispeech.org/api/rest?voice=usenglishfemale&action=convert&text=a&apikey=developerdemokeydeveloperdemokey&speed=0')+'&autostart=1" /> </object>
