3. A personalized voice notification service generates audio versions of
written messages using text-to-speech (TTS) technology. By using this
technology, you can create custom audio notifications tailored to
everyone. As a result, users can receive audio prompts that are more
personalized and engaging, enhancing customer loyalty and
experience.

provide timely and accurate information are some of the benefits that
can be realized. As customers feel appreciated and recognized, a
personalized voice message can enhance the customer experience and
create a more engaging and welcoming environment.
Benefits of using a personalized voice notification service

5. • A personalized voice prompt is an audio message that is customized
by using Text-To-Speech to address the user by name or provide
specific information based on their profile or history. Some common
types of personalised voice prompts are name, profile, context,
location, activity, preference, and mood.
• For example, the prompt for the name attribute could be “Hi [name],
this is a reminder about your appointment tomorrow,” while the value
for the appointment time attribute could be “Your appointment is at
[time] on [date].”
