Text To Speech
What is Text To Speech (TTS)?
Text To Speech (TTS) is a form of speech synthesis that converts text into voice output.
When TTS was first introduced in the mid 1900’s, the voice output sounded much more like a computer voice than a human voice.
After many years of development, TTS still does not sound 100% like a human speaking, but it has come a long way and it is now commonly used in voice broadcast applications.
Can fields be dynamically merged into a voice broadcast message?
Yes! This technique is commonly used by doctor offices.
In a voice broadcast, the TTS portion of the message can be dynamically merged from the phone number list.
Below is an example TTS voice broadcast message for an appointment reminder. The bold words are dynamically inserted from the phone number list.

What does the Text To Speech voice sound like?
Sigma Voice uses Kate NeoSpeech.
Can a human recording be dynamically merged instead of Text To Speech?
Sorry Kate but people want to know!
Yes! A human voice can be used. Keep in mind that this requires human voice recordings for the merge data fields. For example, if the day of the week is in the message, there needs to be a human voice recording for each day of the week.
Sunday, Monday, Tuesday, Wednesday, Thursday, Friday & Saturday
The set up take a few more minutes, but it can be worth it to have an all human voice message.
