WaveNetVocalizer PRO users can add voice customization by adding SSML Tags/Codes inside there Script Text file.


Speech Synthesis Markup Language or SSML allow for more customization in your audio response by providing details on pauses, and audio formatting for acronyms, dates, times, abbreviations, or text that should be censored. Not only that by using SSML tags, you can also customize the Voice Pitch and Speaking Rate of your Speech.


There are three options for setting the value of the pitch attribute:


Relative: Specify a relative value (e.g. "low", "medium", "high", etc) where "medium" is the default pitch.

Semitones: Increase or decrease pitch by "N" semitones using "+Nst" or "-Nst" respectively. Note that "+/-" and "st" are required.

Percentage: Increase or decrease pitch by "N" percent by using "+N%" or "-N%" respectively. Note that "%" is required but "+/-" is optional.


You will find the SSML code examples on Google's Knowledge-base here: https://cloud.google.com/text-to-speech/docs/ssml


To give you an example how it works here is a shot example of SSML markup:

___________________________________________________________________________________


<speak>


This is the default speech of WaveNetVocalizer. But I can customize the Voice Pitch and Speaking Rate using SSML tags.


<break strength="weak"/>


<prosody rate="slow" pitch="-1st"> Here is an example of slower rate and reduced pitch using SSML tag </prosody>


<break strength="weak"/>


<prosody rate="slow" pitch="-2st"> Here is another example of slower rate and lower pitch using SSML tag </prosody>


<break strength="weak"/>


<prosody rate="slow" pitch="-50%"> Here is another example of slower rate and lower pitch using SSML tag </prosody>


<break strength="weak"/>


<prosody rate="fast" pitch="+1st"> Here is an example of faster rate higher pitch using SSML tag </prosody>


<break strength="weak"/>


<prosody rate="fast" pitch="+2st"> Here is another example of faster rate higher pitch using SSML tag </prosody>


<break strength="weak"/>


<prosody rate="fast" pitch="+50%"> Here is another example of faster rate higher pitch using SSML tag </prosody>


<break strength="weak"/>


Did I just amaze you with my speech?


<emphasis level="strong"> But, </emphasis> We are not done yet. <break strength="weak"/>

This is only the beginning. <emphasis level="moderate"> Welcome to WaveNetVocalizer </emphasis>


</speak>
